-Administration Guide
+Backup Client Usage
-====================
+===================
-
-The administration guide.
-
-.. todo:: either add a bit more explanation or remove the previous sentence
-
-Terminology
------------
-
-Backup Content
-~~~~~~~~~~~~~~
-
-When doing deduplication, there are different strategies to get
-optimal results in terms of performance and/or deduplication rates.
-Depending on the type of data, one can split data into *fixed* or *variable*
-sized chunks.
-
-Fixed sized chunking needs almost no CPU performance, and is used to
-backup virtual machine images.
-
-Variable sized chunking needs more CPU power, but is essential to get
-good deduplication rates for file archives.
-
-The backup server supports both strategies.
-
-
-File Archives: ``<name>.pxar``
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-.. see https://moinakg.wordpress.com/2013/06/22/high-performance-content-defined-chunking/
-
-A file archive stores a full directory tree. Content is stored using
-the :ref:`pxar-format`, split into variable sized chunks. The format
-is optimized to achieve good deduplication rates.
-
-
-Image Archives: ``<name>.img``
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-This is used for virtual machine images and other large binary
-data. Content is split into fixed sized chunks.
-
-
-Binary Data (BLOBs)
-^^^^^^^^^^^^^^^^^^^
-
-This type is used to store smaller (< 16MB) binary data such as
-configuration files. Larger files should be stored as image archive.
-
-.. caution:: Please do not store all files as BLOBs. Instead, use the
-   file archive to store whole directory trees.
-
-
-Catalog File: ``catalog.pcat1``
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The catalog file is an index for file archives. It contains
-the list of files and is used to speed-up search operations.
-
-
-The Manifest: ``index.json``
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The manifest contains the list of all backup files, their
-sizes and checksums. It is used to verify the consistency of a
-backup.

-The backup server groups backups by *type*, where *type* is one of:
-
-``vm``
-    This type is used for :term:`virtual machine`\ s. Typically
-    contains the virtual machine's configuration and an image archive
-    for each disk.
-
-``ct``
-    This type is used for :term:`container`\ s. Contains the container's
-    configuration and a single file archive for the container content.
-
-``host``
-    This type is used for backups created from within the backed up machine.
-    Typically this would be a physical host but could also be a virtual machine
-    or container. Such backups may contain file and image archives, there are no restrictions in this regard.
-
-
-Backup ID
-~~~~~~~~~
-
-An unique ID. Usually the virtual machine or container ID. ``host``
-type backups normally use the hostname.
-
-
-Backup Time
-~~~~~~~~~~~
-
-The time when the backup was made.
-
-
-Backup Group
-~~~~~~~~~~~~
-
-The tuple ``<type>/<ID>`` is called a backup group. Such a group
-may contain one or more backup snapshots.
-
-
-Backup Snapshot
-~~~~~~~~~~~~~~~
-
-The triplet ``<type>/<ID>/<time>`` is called a backup snapshot. It
-uniquely identifies a specific backup within a datastore.

-As you can see, the time format is RFC3399_ with Coordinated
-Universal Time (UTC_, identified by the trailing *Z*).

-
-:term:`DataStore`
-~~~~~~~~~~~~~~~~~
-
-A datastore is a place where backups are stored. The current implementation
-uses a directory inside a standard unix file system (``ext4``, ``xfs``
-or ``zfs``) to store the backup data.
-
-Datastores are identified by a simple *ID*. You can configure it
-when setting up the backup server.
-
-
-Backup Server Management
-------------------------
-
-The command line tool to configure and manage the backup server is called
-:command:`proxmox-backup-manager`.
-
-
-Datastore Configuration
-~~~~~~~~~~~~~~~~~~~~~~~
-
-A :term:`datastore` is a place to store backups. You can configure
-multiple datastores. At least one datastore needs to be
-configured. The datastore is identified by a simple `name` and points
-to a directory.
-
-The following command creates a new datastore called ``store1`` on :file:`/backup/disk1/store1`
-
-.. code-block:: console
-
-  # proxmox-backup-manager datastore create store1 /backup/disk1/store1
-
-To list existing datastores run:
-
-.. code-block:: console
-
-  # proxmox-backup-manager datastore list
-  ┌────────┬──────────────────────┬─────────────────────────────┐
-  │ name   │ path                 │ comment                     │
-  ╞════════╪══════════════════════╪═════════════════════════════╡
-  │ store1 │ /backup/disk1/store1 │ This is my default storage. │
-  └────────┴──────────────────────┴─────────────────────────────┘
-
-Finally, it is possible to remove the datastore configuration:
-
-.. code-block:: console
-
-  # proxmox-backup-manager datastore remove store1
-
-.. note:: The above command removes only the datastore configuration. It does
-   not delete any data from the underlying directory.
-
-
-File Layout
-^^^^^^^^^^^
-
-.. todo:: Add datastore file layout example
-
-
-User Management
-~~~~~~~~~~~~~~~
-
-Proxmox Backup support several authentication realms, and you need to
-choose the realm when you add a new user. Possible realms are:
-
-:pam: Linux PAM standard authentication. Use this if you want to
-      authenticate as Linux system user (Users needs to exist on the
-      system).
-
-:pbs: Proxmox Backup Server realm. This type stores hashed passwords in
-      ``/etc/proxmox-backup/shadow.json``.
-
-After installation, there is a single user ``root@pam``, which
-corresponds to the Unix superuser. You can use the
-``proxmox-backup-manager`` command line tool to list or manipulate
-users:
-
-.. code-block:: console
-
-  # proxmox-backup-manager user list
-  ┌─────────────┬────────┬────────┬───────────┬──────────┬────────────────┬────────────────────┐
-  │ userid      │ enable │ expire │ firstname │ lastname │ email          │ comment            │

-  └─────────────┴────────┴────────┴───────────┴──────────┴────────────────┴────────────────────┘
-
-The superuser has full administration rights on everything, so you
-normally want to add other users with less privileges:
-
-.. code-block:: console
-
-  # proxmox-backup-manager user create john@pbs --email john@example.com
-
-The create command lets you specify many option like ``--email`` or
-``--password``, but you can update or change any of them using the
-update command later:
-
-.. code-block:: console
-
-  # proxmox-backup-manager user update john@pbs --firstname John --lastname Smith
-  # proxmox-backup-manager user update john@pbs --comment "An example user."
-
-
-.. todo:: Mention how to set password without passing plaintext password as cli argument.

-Newly created users do not have an permissions. Please read the next
-section to learn how to set access permissions.
-
-If you want to disable an user account, you can do that by setting ``--enable`` to ``0``
-
-.. code-block:: console
-
-  # proxmox-backup-manager user update john@pbs --enable 0

-Access Control
-~~~~~~~~~~~~~~
-
-Users do not have any permission by default. Instead you need to
-specify what is allowed and what not. You can do this by assigning
-roles to users on specific objects like datastores or remotes. The
-following roles exist:
-
-**Admin**
-  The Administrator can do anything.
-
-**Audit**
-  An Auditor can view things, but is not allowed to change settings.
-
-**NoAccess**
-  Disable Access - nothing is allowed.
-
-**DatastoreAdmin**
-  Can do anything on datastores.
-
-**DatastoreAudit**
-  Can view datastore settings and list content. But
-  is not allowed to read the actual data.
-
-**DataStoreReader**
-  Can Inspect datastore content and can do restores.
-
-**DataStoreBackup**
-  Can backup and restore owned backups.
-
-**DatastorePowerUser**
-  Can backup, restore, and prune owned backups.
-
-**RemoteAdmin**
-  Can do anything on remotes.
-
-**RemoteAudit**
-  Can view remote settings.
-
-**RemoteSyncOperator**
-  Is allowed to read data from a remote.

-Backup Client usage
--------------------
 
 The command line client is called :command:`proxmox-backup-client`.
 
 
-Respository Locations
+Repository Locations
-~~~~~~~~~~~~~~~~~~~~~
+--------------------
 
 The client uses the following notation to specify a datastore repository
 on the backup server.
 
-  [[username@]server:]datastore
+  [[username@]server[:port]:]datastore
 
-The default value for ``username`` ist ``root``. If no server is specified, the
+The default value for ``username`` is ``root@pam``.  If no server is specified,

+the default is the local host (``localhost``).
+
+You can specify a port if your backup server is only reachable on a different
+port (e.g. with NAT and port forwarding).
+
+Note that if the server is an IPv6 address, you have to write it with
+square brackets (e.g. [fe80::01]).
 
 You can pass the repository with the ``--repository`` command
 line option, or by setting the ``PBS_REPOSITORY`` environment
 variable.

+
+Using a master key to store and recover encryption keys
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can also use ``proxmox-backup-client key`` to create an RSA public/private
+key pair, which can be used to store an encrypted version of the symmetric
+backup encryption key alongside each backup and recover it later.
+
+To set up a master key:
+
+1. Create an encryption key for the backup:
+
+   .. code-block:: console
+
+     # proxmox-backup-client key create
+     creating default key at: "~/.config/proxmox-backup/encryption-key.json"
+     Encryption Key Password: **********
+     ...
+
+   The resulting file will be saved to ``~/.config/proxmox-backup/encryption-key.json``.
+
+2. Create an RSA public/private key pair:
+
+   .. code-block:: console
+
+     # proxmox-backup-client key create-master-key
+     Master Key Password: *********
+     ...
+
+   This will create two files in your current directory, ``master-public.pem``
+   and ``master-private.pem``.
+
+3. Import the newly created ``master-public.pem`` public certificate, so that
+   ``proxmox-backup-client`` can find and use it upon backup.
+
+   .. code-block:: console
+
+     # proxmox-backup-client key import-master-pubkey /path/to/master-public.pem
+     Imported public master key to "~/.config/proxmox-backup/master-public.pem"
+
+4. With all these files in place, run a backup job:
+
+   .. code-block:: console
+
+     # proxmox-backup-client backup etc.pxar:/etc
+
+   The key will be stored in your backup, under the name ``rsa-encrypted.key``.
+
+   .. Note:: The ``--keyfile`` parameter can be excluded, if the encryption key
+     is in the default path. If you specified another path upon creation, you
+     must pass the ``--keyfile`` parameter.
+
+5. To test that everything worked, you can restore the key from the backup:
+
+   .. code-block:: console
+
+     # proxmox-backup-client restore /path/to/backup/ rsa-encrypted.key /path/to/target
+
+   .. Note:: You should not need an encryption key to extract this file. However, if
+     a key exists at the default location
+     (``~/.config/proxmox-backup/encryption-key.json``) the program will prompt
+     you for an encryption key password. Simply moving ``encryption-key.json``
+     out of this directory will fix this issue.
+
+6. Then, use the previously generated master key to decrypt the file:
+
+   .. code-block:: console
+
+     # openssl rsautl -decrypt -inkey master-private.pem -in rsa-encrypted.key -out /path/to/target
+     Enter pass phrase for ./master-private.pem: *********
+
+7. The target file will now contain the encryption key information in plain
+   text. The success of this can be confirmed by passing the resulting ``json``
+   file, with the ``--keyfile`` parameter, when decrypting files from the backup.
+
+.. warning:: Without their key, backed up files will be inaccessible. Thus, you should
+  keep keys ordered and in a place that is separate from the contents being
+  backed up. It can happen, for example, that you back up an entire system, using
+  a key on that system. If the system then becomes inaccessible for any reason
+  and needs to be restored, this will not be possible as the encryption key will be
+  lost along with the broken system. In preparation for the worst case scenario,
+  you should consider keeping a paper copy of this key locked away in
+  a safe place.

+Calendar Events
+===============
+
+Introduction and Format
+-----------------------
+
+Certain tasks, for example pruning and garbage collection, need to be
+performed on a regular basis. Proxmox Backup Server uses a format inspired
+by the systemd Time and Date Specification (see `systemd.time manpage`_)
+called `calendar events` for its schedules.
+
+`Calendar events` are expressions to specify one or more points in time.
+They are mostly compatible with systemd's calendar events.
+
+The general format is as follows:
+
+.. code-block:: console
+  :caption: Calendar event
+
+  [WEEKDAY] [[YEARS-]MONTHS-DAYS] [HOURS:MINUTES[:SECONDS]]
+
+Note that there either has to be at least a weekday, date or time part.
+If the weekday or date part is omitted, all (week)days are included.
+If the time part is omitted, the time 00:00:00 is implied.
+(e.g. '2020-01-01' refers to '2020-01-01 00:00:00')
+
+Weekdays are specified with the abbreviated English version:
+`mon, tue, wed, thu, fri, sat, sun`.
+
+Each field can contain multiple values in the following formats:
+
+* comma-separated: e.g.,  01,02,03
+* as a range: e.g., 01..10
+* as a repetition: e.g, 05/10 (means starting at 5 every 10)
+* and a combination of the above: e.g., 01,05..10,12/02
+* or a `*` for every possible value: e.g., \*:00
+
+There are some special values that have specific meaning:
+
+=================================  ==============================
+Value                              Syntax
+=================================  ==============================
+`minutely`                         `*-*-* *:*:00`
+`hourly`                           `*-*-* *:00:00`
+`daily`                            `*-*-* 00:00:00`
+`weekly`                           `mon *-*-* 00:00:00`
+`monthly`                          `*-*-01 00:00:00`
+`yearly` or `annually`              `*-01-01 00:00:00`
+`quarterly`                        `*-01,04,07,10-01 00:00:00`

+
+
+Differences to systemd
+----------------------
+
+Not all features of systemd calendar events are implemented:
+
+* no Unix timestamps (e.g. `@12345`): instead use date and time to specify
+  a specific point in time
+* no timezone: all schedules use the set timezone on the server
+* no sub-second resolution
+* no reverse day syntax (e.g. 2020-03~01)
+* no repetition of ranges (e.g. 1..10/2)
+
+Notes on scheduling
+-------------------
+
+In `Proxmox Backup`_ scheduling for most tasks is done in the
+`proxmox-backup-proxy`. This daemon checks all job schedules
+if they are due every minute. This means that even if
+`calendar events` can contain seconds, it will only be checked
+once a minute.
+
+Also, all schedules will be checked against the timezone set
+in the `Proxmox Backup`_ server.

+FAQ
+===
+
+What distribution is Proxmox Backup Server (PBS) based on?
+----------------------------------------------------------
+
+Proxmox Backup Server is based on `Debian GNU/Linux <https://www.debian.org/>`_.
+
+
+Which platforms are supported as a backup source (client)?
+----------------------------------------------------------
+
+The client tool works on most modern Linux systems, meaning you are not limited
+to Debian-based backups.
+
+
+Will Proxmox Backup Server run on a 32-bit processor?
+-----------------------------------------------------
+
+Proxmox Backup Server only supports 64-bit CPUs (AMD or Intel). There are no
+future plans to support 32-bit processors.
+
+
+How long will my Proxmox Backup Server version be supported?
+------------------------------------------------------------
+
++-----------------------+--------------------+---------------+------------+--------------------+
+|Proxmox Backup Version | Debian Version     | First Release | Debian EOL | Proxmox Backup EOL |
++=======================+====================+===============+============+====================+

++-----------------------+--------------------+---------------+------------+--------------------+
+
+
+Can I copy or synchronize my datastore to another location?
+-----------------------------------------------------------
+
+Proxmox Backup Server allows you to copy or synchronize datastores to other
+locations, through the use of *Remotes* and *Sync Jobs*. *Remote* is the term
+given to a separate server, which has a datastore that can be synced to a local store.
+A *Sync Job* is the process which is used to pull the contents of a datastore from
+a *Remote* to a local datastore.
+
+
+Can Proxmox Backup Server verify data integrity of a backup archive?
+--------------------------------------------------------------------
+
+Proxmox Backup Server uses a built-in SHA-256 checksum algorithm, to ensure
+data integrity. Within each backup, a manifest file (index.json) is created,
+which contains a list of all the backup files, along with their sizes and
+checksums. This manifest file is used to verify the integrity of each backup.
+
+
+When backing up to remote servers, do I have to trust the remote server?
+------------------------------------------------------------------------
+
+Proxmox Backup Server supports client-side encryption, meaning your data is
+encrypted before it reaches the server. Thus, in the event that an attacker
+gains access to the server, they will not be able to read the data.
+
+.. note:: Encryption is not enabled by default. To set up encryption, see the
+  `Encryption
+  <https://pbs.proxmox.com/docs/administration-guide.html#encryption>`_ section
+  of the Proxmox Backup Server Administration Guide.
+
+
+Is the backup incremental/deduplicated?
+---------------------------------------
+
+With Proxmox Backup Server, backups are sent incremental and data is
+deduplicated on the server.
+This minimizes both the storage consumed and the network impact.

 Software Stack
 --------------
 
-.. todo:: Eplain why we use Rust (and Flutter)
+Proxmox Backup Server consists of multiple components:
-	  
+
+* A server-daemon providing, among other things, a RESTful API, super-fast
+  asynchronous tasks, lightweight usage statistic collection, scheduling
+  events, strict separation of privileged and unprivileged execution
+  environments
+* A JavaScript management web interface
+* A management CLI tool for the server (`proxmox-backup-manager`)
+* A client CLI tool (`proxmox-backup-client`) to access the server easily from
+  any `Linux amd64` environment
+
+Aside from the web interface, everything is written in the Rust programming
+language.
+
+ "The Rust programming language helps you write faster, more reliable software.
+ High-level ergonomics and low-level control are often at odds in programming
+ language design; Rust challenges that conflict. Through balancing powerful
+ technical capacity and a great developer experience, Rust gives you the option
+ to control low-level details (such as memory usage) without all the hassle
+ traditionally associated with such control."

 History
 -------
 
-.. todo:: Add development History of the product
+Backup is, and always was, as central aspect of IT administration.
+The need to recover from data loss is fundamental and increases with
+virtualization.
 
+Not surprisingly, we shipped a backup tool with Proxmox VE from the
+beginning. The tool is called ``vzdump`` and is able to make
+consistent snapshots of running LXC containers and KVM virtual
+machines.
+
+But ``vzdump`` only allowed for full backups. While this is perfect
+for small backups, it becomes a burden for users with large VMs. Both
+backup time and space usage was too large for this case, specially
+when Users want to keep many backups of the same VMs. We need
+deduplication and incremental backups to solve those problems.
+
+Back in October 2018 development started. We had been looking into
+several technologies and frameworks and finally decided to use
+:term:`Rust` as implementation language to provide high speed and
+memory efficiency. The 2018-edition of Rust seemed to be promising and
+useful for our requirements.
+
+In July 2020 we released the first beta version of Proxmox Backup
+Server, followed by a first stable version in November 2020. With the
+support of incremental, fully deduplicated backups, Proxmox Backup
+significantly reduces the network load and saves valuable storage
+space.

+
+ZFS on Linux
+------------
+
+ZFS is a combined file system and logical volume manager designed by
+Sun Microsystems. There is no need to manually compile ZFS modules - all
+packages are included.
+
+By using ZFS, it's possible to achieve maximum enterprise features with
+low budget hardware, but also high performance systems by leveraging
+SSD caching or even SSD only setups. ZFS can replace cost intense
+hardware raid cards by moderate CPU and memory load combined with easy
+management.
+
+General ZFS advantages
+
+* Easy configuration and management with GUI and CLI.
+* Reliable
+* Protection against data corruption
+* Data compression on file system level
+* Snapshots
+* Copy-on-write clone
+* Various raid levels: RAID0, RAID1, RAID10, RAIDZ-1, RAIDZ-2 and RAIDZ-3
+* Can use SSD for cache
+* Self healing
+* Continuous integrity checking
+* Designed for high storage capacities
+* Asynchronous replication over network
+* Open Source
+* Encryption
+
+Hardware
+~~~~~~~~~
+
+ZFS depends heavily on memory, so you need at least 8GB to start. In
+practice, use as much you can get for your hardware/budget. To prevent
+data corruption, we recommend the use of high quality ECC RAM.
+
+If you use a dedicated cache and/or log disk, you should use an
+enterprise class SSD (e.g. Intel SSD DC S3700 Series). This can
+increase the overall performance significantly.
+
+IMPORTANT: Do not use ZFS on top of hardware controller which has its
+own cache management. ZFS needs to directly communicate with disks. An
+HBA adapter is the way to go, or something like LSI controller flashed
+in ``IT`` mode.
+
+
+ZFS Administration
+~~~~~~~~~~~~~~~~~~
+
+This section gives you some usage examples for common tasks. ZFS
+itself is really powerful and provides many options. The main commands
+to manage ZFS are `zfs` and `zpool`. Both commands come with great
+manual pages, which can be read with:
+
+.. code-block:: console
+
+  # man zpool
+  # man zfs
+
+Create a new zpool
+^^^^^^^^^^^^^^^^^^
+
+To create a new pool, at least one disk is needed. The `ashift` should
+have the same sector-size (2 power of `ashift`) or larger as the
+underlying disk.
+
+.. code-block:: console
+
+  # zpool create -f -o ashift=12 <pool> <device>
+
+Create a new pool with RAID-0
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Minimum 1 disk
+
+.. code-block:: console
+
+  # zpool create -f -o ashift=12 <pool> <device1> <device2>
+
+Create a new pool with RAID-1
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Minimum 2 disks
+
+.. code-block:: console
+
+  # zpool create -f -o ashift=12 <pool> mirror <device1> <device2>
+
+Create a new pool with RAID-10
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Minimum 4 disks
+
+.. code-block:: console
+
+  # zpool create -f -o ashift=12 <pool> mirror <device1> <device2> mirror <device3> <device4>
+
+Create a new pool with RAIDZ-1
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Minimum 3 disks
+
+.. code-block:: console
+
+  # zpool create -f -o ashift=12 <pool> raidz1 <device1> <device2> <device3>
+
+Create a new pool with RAIDZ-2
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Minimum 4 disks
+
+.. code-block:: console
+
+  # zpool create -f -o ashift=12 <pool> raidz2 <device1> <device2> <device3> <device4>
+
+Create a new pool with cache (L2ARC)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+It is possible to use a dedicated cache drive partition to increase
+the performance (use SSD).
+
+As `<device>` it is possible to use more devices, like it's shown in
+"Create a new pool with RAID*".
+
+.. code-block:: console
+
+  # zpool create -f -o ashift=12 <pool> <device> cache <cache_device>
+
+Create a new pool with log (ZIL)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+It is possible to use a dedicated cache drive partition to increase
+the performance (SSD).
+
+As `<device>` it is possible to use more devices, like it's shown in
+"Create a new pool with RAID*".
+
+.. code-block:: console
+
+  # zpool create -f -o ashift=12 <pool> <device> log <log_device>
+
+Add cache and log to an existing pool
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you have a pool without cache and log. First partition the SSD in
+2 partition with `parted` or `gdisk`
+
+.. important:: Always use GPT partition tables.
+
+The maximum size of a log device should be about half the size of
+physical memory, so this is usually quite small. The rest of the SSD
+can be used as cache.
+
+.. code-block:: console
+
+  # zpool add -f <pool> log <device-part1> cache <device-part2>
+
+
+Changing a failed device
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. code-block:: console
+
+  # zpool replace -f <pool> <old device> <new device>
+
+
+Changing a failed bootable device
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Depending on how Proxmox Backup was installed it is either using `grub` or `systemd-boot`
+as bootloader.
+
+The first steps of copying the partition table, reissuing GUIDs and replacing
+the ZFS partition are the same. To make the system bootable from the new disk,
+different steps are needed which depend on the bootloader in use.
+
+.. code-block:: console
+
+  # sgdisk <healthy bootable device> -R <new device>
+  # sgdisk -G <new device>
+  # zpool replace -f <pool> <old zfs partition> <new zfs partition>
+
+.. NOTE:: Use the `zpool status -v` command to monitor how far the resilvering process of the new disk has progressed.
+
+With `systemd-boot`:
+
+.. code-block:: console
+
+  # pve-efiboot-tool format <new disk's ESP>
+  # pve-efiboot-tool init <new disk's ESP>
+
+.. NOTE:: `ESP` stands for EFI System Partition, which is setup as partition #2 on
+  bootable disks setup by the {pve} installer since version 5.4. For details, see
+  xref:sysboot_systemd_boot_setup[Setting up a new partition for use as synced ESP].
+
+With `grub`:
+
+Usually `grub.cfg` is located in `/boot/grub/grub.cfg`
+
+.. code-block:: console
+
+  # grub-install <new disk>
+  # grub-mkconfig -o /path/to/grub.cfg
+
+
+Activate E-Mail Notification
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+ZFS comes with an event daemon, which monitors events generated by the
+ZFS kernel module. The daemon can also send emails on ZFS events like
+pool errors. Newer ZFS packages ship the daemon in a separate package,
+and you can install it using `apt-get`:
+
+.. code-block:: console
+
+  # apt-get install zfs-zed
+
+To activate the daemon it is necessary to edit `/etc/zfs/zed.d/zed.rc` with your
+favorite editor, and uncomment the `ZED_EMAIL_ADDR` setting:
+
+.. code-block:: console
+
+  ZED_EMAIL_ADDR="root"
+
+Please note Proxmox Backup forwards mails to `root` to the email address
+configured for the root user.
+
+IMPORTANT: The only setting that is required is `ZED_EMAIL_ADDR`. All
+other settings are optional.
+
+Limit ZFS Memory Usage
+^^^^^^^^^^^^^^^^^^^^^^
+
+It is good to use at most 50 percent (which is the default) of the
+system memory for ZFS ARC to prevent performance shortage of the
+host. Use your preferred editor to change the configuration in
+`/etc/modprobe.d/zfs.conf` and insert:
+
+.. code-block:: console
+
+  options zfs zfs_arc_max=8589934592
+
+This example setting limits the usage to 8GB.
+
+.. IMPORTANT:: If your root file system is ZFS you must update your initramfs every time this value changes:
+
+.. code-block:: console
+
+  # update-initramfs -u
+
+
+SWAP on ZFS
+^^^^^^^^^^^
+
+Swap-space created on a zvol may generate some troubles, like blocking the
+server or generating a high IO load, often seen when starting a Backup
+to an external Storage.
+
+We strongly recommend to use enough memory, so that you normally do not
+run into low memory situations. Should you need or want to add swap, it is
+preferred to create a partition on a physical disk and use it as swap device.
+You can leave some space free for this purpose in the advanced options of the
+installer. Additionally, you can lower the `swappiness` value. 
+A good value for servers is 10:
+
+.. code-block:: console
+
+  # sysctl -w vm.swappiness=10

+ZFS Compression
+^^^^^^^^^^^^^^^
+
+To activate compression:
+.. code-block:: console
+
+  # zpool set compression=lz4 <pool>
+
+We recommend using the `lz4` algorithm, since it adds very little CPU overhead.
+Other algorithms such as `lzjb` and `gzip-N` (where `N` is an integer `1-9` representing
+the compression ratio, 1 is fastest and 9 is best compression) are also available.
+Depending on the algorithm and how compressible the data is, having compression enabled can even increase
+I/O performance.
+
+You can disable compression at any time with:
+.. code-block:: console
+
+  # zfs set compression=off <dataset>
+
+Only new blocks will be affected by this change.
+
+.. _local_zfs_special_device:
+
+ZFS Special Device
+^^^^^^^^^^^^^^^^^^
+
+Since version 0.8.0 ZFS supports `special` devices. A `special` device in a
+pool is used to store metadata, deduplication tables, and optionally small
+file blocks.
+
+A `special` device can improve the speed of a pool consisting of slow spinning
+hard disks with a lot of metadata changes. For example workloads that involve
+creating, updating or deleting a large number of files will benefit from the
+presence of a `special` device. ZFS datasets can also be configured to store
+whole small files on the `special` device which can further improve the
+performance. Use fast SSDs for the `special` device.
+
+.. IMPORTANT:: The redundancy of the `special` device should match the one of the
+  pool, since the `special` device is a point of failure for the whole pool.
+
+.. WARNING:: Adding a `special` device to a pool cannot be undone!
+
+Create a pool with `special` device and RAID-1:
+
+.. code-block:: console
+
+  # zpool create -f -o ashift=12 <pool> mirror <device1> <device2> special mirror <device3> <device4>
+
+Adding a `special` device to an existing pool with RAID-1:
+
+.. code-block:: console
+
+  # zpool add <pool> special mirror <device1> <device2>
+
+ZFS datasets expose the `special_small_blocks=<size>` property. `size` can be
+`0` to disable storing small file blocks on the `special` device or a power of
+two in the range between `512B` to `128K`. After setting the property new file
+blocks smaller than `size` will be allocated on the `special` device.
+
+.. IMPORTANT:: If the value for `special_small_blocks` is greater than or equal to
+  the `recordsize` (default `128K`) of the dataset, *all* data will be written to
+  the `special` device, so be careful!
+
+Setting the `special_small_blocks` property on a pool will change the default
+value of that property for all child ZFS datasets (for example all containers
+in the pool will opt in for small file blocks).
+
+Opt in for all file smaller than 4K-blocks pool-wide:
+
+.. code-block:: console
+
+  # zfs set special_small_blocks=4K <pool>
+
+Opt in for small file blocks for a single dataset:
+
+.. code-block:: console
+
+  # zfs set special_small_blocks=4K <pool>/<filesystem>
+
+Opt out from small file blocks for a single dataset:
+
+.. code-block:: console
+
+  # zfs set special_small_blocks=0 <pool>/<filesystem>
+
+Troubleshooting
+^^^^^^^^^^^^^^^
+
+Corrupted cachefile
+
+In case of a corrupted ZFS cachefile, some volumes may not be mounted during
+boot until mounted manually later.
+
+For each pool, run:
+
+.. code-block:: console
+
+  # zpool set cachefile=/etc/zfs/zpool.cache POOLNAME
+
+and afterwards update the `initramfs` by running:
+
+.. code-block:: console
+
+  # update-initramfs -u -k all
+
+and finally reboot your node.
+
+Sometimes the ZFS cachefile can get corrupted, and `zfs-import-cache.service`
+doesn't import the pools that aren't present in the cachefile.
+
+Another workaround to this problem is enabling the `zfs-import-scan.service`,
+which searches and imports pools via device scanning (usually slower).

+:term:`Remote`
+--------------
+
+A remote refers to a separate Proxmox Backup Server installation and a user on that
+installation, from which you can `sync` datastores to a local datastore with a
+`Sync Job`. You can configure remotes in the web interface, under **Configuration
+-> Remotes**. Alternatively, you can use the ``remote`` subcommand. The
+configuration information for remotes is stored in the file
+``/etc/proxmox-backup/remote.cfg``.
+
+.. image:: images/screenshots/pbs-gui-remote-add.png
+  :align: right
+  :alt: Add a remote
+
+To add a remote, you need its hostname or IP, a userid and password on the
+remote, and its certificate fingerprint. To get the fingerprint, use the
+``proxmox-backup-manager cert info`` command on the remote, or navigate to
+**Dashboard** in the remote's web interface and select **Show Fingerprint**.
+
+.. code-block:: console
+
+  # proxmox-backup-manager cert info |grep Fingerprint
+  Fingerprint (sha256): 64:d3:ff:3a:50:38:53:5a:9b:f7:50:...:ab:fe
+
+Using the information specified above, you can add a remote from the **Remotes**
+configuration panel, or by using the command:

+
+Proxmox Backup Server uses the package smartmontools. This is a set of tools
+used to monitor and control the S.M.A.R.T. system for local hard disks. If a
+disk supports S.M.A.R.T. capability, and you have this enabled, you can

+
+.. note:: This functionality may also be accessed directly through the use of
+  the ``smartctl`` command, which comes as part of the smartmontools package
+  (see ``man smartctl`` for more details).
+
+
+.. _datastore_intro:
+
+:term:`DataStore`
+-----------------
+
+A datastore refers to a location at which backups are stored. The current
+implementation uses a directory inside a standard Unix file system (``ext4``,
+``xfs`` or ``zfs``) to store the backup data.
+
+Datastores are identified by a simple *ID*. You can configure this
+when setting up the datastore. The configuration information for datastores
+is stored in the file ``/etc/proxmox-backup/datastore.cfg``.
+
+.. note:: The `File Layout`_ requires the file system to support at least *65538*
+   subdirectories per directory. That number comes from the 2\ :sup:`16`
+   pre-created chunk namespace directories, and the ``.`` and ``..`` default
+   directory entries. This requirement excludes certain filesystems and
+   filesystem configuration from being supported for a datastore. For example,
+   ``ext3`` as a whole or ``ext4`` with the ``dir_nlink`` feature manually disabled.
+
+
+Datastore Configuration
+~~~~~~~~~~~~~~~~~~~~~~~
+
+.. image:: images/screenshots/pbs-gui-datastore.png
+  :align: right
+  :alt: Datastore Overview
+
+You can configure multiple datastores. Minimum one datastore needs to be
+configured. The datastore is identified by a simple *name* and points to a
+directory on the filesystem. Each datastore also has associated retention
+settings of how many backup snapshots for each interval of ``hourly``,
+``daily``, ``weekly``, ``monthly``, ``yearly`` as well as a time-independent
+number of backups to keep in that store. :ref:`backup-pruning` and
+:ref:`garbage collection <garbage-collection>` can also be configured to run
+periodically based on a configured schedule (see :ref:`calendar-events`) per datastore.
+
+
+Creating a Datastore
+^^^^^^^^^^^^^^^^^^^^
+.. image:: images/screenshots/pbs-gui-datastore-create-general.png
+  :align: right
+  :alt: Create a datastore
+
+You can create a new datastore from the web GUI, by navigating to **Datastore** in
+the menu tree and clicking **Create**. Here:
+
+* *Name* refers to the name of the datastore
+* *Backing Path* is the path to the directory upon which you want to create the
+  datastore
+* *GC Schedule* refers to the time and intervals at which garbage collection
+  runs
+* *Prune Schedule* refers to the frequency at which pruning takes place
+* *Prune Options* set the amount of backups which you would like to keep (see :ref:`backup-pruning`).
+
+Alternatively you can create a new datastore from the command line. The
+following command creates a new datastore called ``store1`` on :file:`/backup/disk1/store1`
+
+.. code-block:: console
+
+  # proxmox-backup-manager datastore create store1 /backup/disk1/store1
+
+
+Managing Datastores
+^^^^^^^^^^^^^^^^^^^
+
+To list existing datastores from the command line run:
+
+.. code-block:: console
+
+  # proxmox-backup-manager datastore list
+  ┌────────┬──────────────────────┬─────────────────────────────┐
+  │ name   │ path                 │ comment                     │
+  ╞════════╪══════════════════════╪═════════════════════════════╡
+  │ store1 │ /backup/disk1/store1 │ This is my default storage. │
+  └────────┴──────────────────────┴─────────────────────────────┘
+
+You can change the garbage collection and prune settings of a datastore, by
+editing the datastore from the GUI or by using the ``update`` subcommand. For
+example, the below command changes the garbage collection schedule using the
+``update`` subcommand and prints the properties of the datastore with the
+``show`` subcommand:
+
+.. code-block:: console
+
+  # proxmox-backup-manager datastore update store1 --gc-schedule 'Tue 04:27'
+  # proxmox-backup-manager datastore show store1
+  ┌────────────────┬─────────────────────────────┐
+  │ Name           │ Value                       │
+  ╞════════════════╪═════════════════════════════╡
+  │ name           │ store1                      │
+  ├────────────────┼─────────────────────────────┤
+  │ path           │ /backup/disk1/store1        │
+  ├────────────────┼─────────────────────────────┤
+  │ comment        │ This is my default storage. │
+  ├────────────────┼─────────────────────────────┤
+  │ gc-schedule    │ Tue 04:27                   │
+  ├────────────────┼─────────────────────────────┤
+  │ keep-last      │ 7                           │
+  ├────────────────┼─────────────────────────────┤
+  │ prune-schedule │ daily                       │
+  └────────────────┴─────────────────────────────┘
+
+Finally, it is possible to remove the datastore configuration:
+
+.. code-block:: console
+
+  # proxmox-backup-manager datastore remove store1
+
+.. note:: The above command removes only the datastore configuration. It does
+   not delete any data from the underlying directory.
+
+
+File Layout
+^^^^^^^^^^^
+
+After creating a datastore, the following default layout will appear:
+
+.. code-block:: console
+
+  # ls -arilh /backup/disk1/store1
+  276493 -rw-r--r-- 1 backup backup       0 Jul  8 12:35 .lock
+  276490 drwxr-x--- 1 backup backup 1064960 Jul  8 12:35 .chunks
+
+`.lock` is an empty file used for process locking.
+
+The `.chunks` directory contains folders, starting from `0000` and taking hexadecimal values until `ffff`. These
+directories will store the chunked data after a backup operation has been executed.
+
+.. code-block:: console
+
+ # ls -arilh /backup/disk1/store1/.chunks

+System Requirements
+-------------------
+
+We recommend using high quality server hardware when running Proxmox Backup in
+production. To further decrease the impact of a failed host, you can set up
+periodic, efficient, incremental :ref:`datastore synchronization <syncjobs>`
+from other Proxmox Backup Server instances.
+
+Minimum Server Requirements, for Evaluation
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+These minimum requirements are for evaluation purposes only and should not be
+used in production.
+
+* CPU: 64bit (*x86-64* or *AMD64*), 2+ Cores
+
+* Memory (RAM): 2 GB RAM
+
+* Hard drive: more than 8GB of space.
+
+* Network card (NIC)
+
+
+Recommended Server System Requirements
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+* CPU: Modern AMD or Intel 64-bit based CPU, with at least 4 cores
+
+* Memory: minimum 4 GiB for the OS, filesystem cache and Proxmox Backup Server
+  daemons. Add at least another GiB per TiB storage space.
+
+* OS storage:
+
+  * 32 GiB, or more, free storage space
+  * Use a hardware RAID with battery protected write cache (*BBU*) or a

+    controller).
+
+* Backup storage:
+
+  * Use only SSDs, for best results

+Terminology
+===========
+
+Backup Content
+--------------
+
+When doing deduplication, there are different strategies to get
+optimal results in terms of performance and/or deduplication rates.
+Depending on the type of data, it can be split into *fixed* or *variable*
+sized chunks.
+
+Fixed sized chunking requires minimal CPU power, and is used to
+backup virtual machine images.
+
+Variable sized chunking needs more CPU power, but is essential to get
+good deduplication rates for file archives.
+
+The Proxmox Backup Server supports both strategies.
+
+
+Image Archives: ``<name>.img``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is used for virtual machine images and other large binary
+data. Content is split into fixed-sized chunks.
+
+
+File Archives: ``<name>.pxar``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. see https://moinakg.wordpress.com/2013/06/22/high-performance-content-defined-chunking/
+
+A file archive stores a full directory tree. Content is stored using
+the :ref:`pxar-format`, split into variable-sized chunks. The format
+is optimized to achieve good deduplication rates.
+
+
+Binary Data (BLOBs)
+~~~~~~~~~~~~~~~~~~~
+
+This type is used to store smaller (< 16MB) binary data such as
+configuration files. Larger files should be stored as image archive.
+
+.. caution:: Please do not store all files as BLOBs. Instead, use the
+   file archive to store whole directory trees.
+
+
+Catalog File: ``catalog.pcat1``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The catalog file is an index for file archives. It contains
+the list of files and is used to speed up search operations.
+
+
+The Manifest: ``index.json``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The manifest contains the list of all backup files, their
+sizes and checksums. It is used to verify the consistency of a
+backup.
+
+
+Backup Type
+-----------
+
+The backup server groups backups by *type*, where *type* is one of:
+
+``vm``
+    This type is used for :term:`virtual machine`\ s. Typically
+    consists of the virtual machine's configuration file and an image archive
+    for each disk.
+
+``ct``
+    This type is used for :term:`container`\ s. Consists of the container's
+    configuration and a single file archive for the filesystem content.
+
+``host``
+    This type is used for backups created from within the backed up machine.
+    Typically this would be a physical host but could also be a virtual machine
+    or container. Such backups may contain file and image archives, there are no restrictions in this regard.
+
+
+Backup ID
+---------
+
+A unique ID. Usually the virtual machine or container ID. ``host``
+type backups normally use the hostname.
+
+
+Backup Time
+-----------
+
+The time when the backup was made.
+
+
+Backup Group
+------------
+
+The tuple ``<type>/<ID>`` is called a backup group. Such a group
+may contain one or more backup snapshots.
+
+
+Backup Snapshot
+---------------
+
+The triplet ``<type>/<ID>/<time>`` is called a backup snapshot. It
+uniquely identifies a specific backup within a datastore.

+Newly created users do not have any permissions. Please read the next
+section to learn how to set access permissions.
+
+If you want to disable a user account, you can do that by setting ``--enable`` to ``0``
+
+.. code-block:: console
+
+  # proxmox-backup-manager user update john@pbs --enable 0
+
+Or completely remove the user with:
+
+.. code-block:: console
+
+  # proxmox-backup-manager user remove john@pbs
+
+
+.. _user_acl:
+
+Access Control
+--------------
+
+By default new users do not have any permission. Instead you need to
+specify what is allowed and what is not. You can do this by assigning
+roles to users on specific objects like datastores or remotes. The
+following roles exist:
+
+**NoAccess**
+  Disable Access - nothing is allowed.
+
+**Admin**
+  Can do anything.
+
+**Audit**
+  Can view things, but is not allowed to change settings.
+
+**DatastoreAdmin**
+  Can do anything on datastores.
+
+**DatastoreAudit**
+  Can view datastore settings and list content. But
+  is not allowed to read the actual data.
+
+**DatastoreReader**
+  Can Inspect datastore content and can do restores.
+
+**DatastoreBackup**
+  Can backup and restore owned backups.
+
+**DatastorePowerUser**
+  Can backup, restore, and prune owned backups.
+
+**RemoteAdmin**
+  Can do anything on remotes.
+
+**RemoteAudit**
+  Can view remote settings.
+
+**RemoteSyncOperator**
+  Is allowed to read data from a remote.
+
+.. image:: images/screenshots/pbs-gui-permissions-add.png
+  :align: right
+  :alt: Add permissions for user
+
+Access permission information is stored in ``/etc/proxmox-backup/acl.cfg``. The
+file contains 5 fields, separated using a colon (':') as a delimiter. A typical
+entry takes the form:
+
+``acl:1:/datastore:john@pbs:DatastoreBackup``
+
+The data represented in each field is as follows:
+
+#. ``acl`` identifier
+#. A ``1`` or ``0``, representing whether propagation is enabled or disabled,
+   respectively
+#. The object on which the permission is set. This can be a specific object
+   (single datastore, remote, etc.) or a top level object, which with
+   propagation enabled, represents all children of the object also.
+#. The user for which the permission is set
+#. The role being set
+
+You can manage datastore permissions from **Configuration -> Permissions** in the
+web interface. Likewise, you can use the ``acl`` subcommand to manage and
+monitor user permissions from the command line. For example, the command below
+will add the user ``john@pbs`` as a **DatastoreAdmin** for the datastore
+``store1``, located at ``/backup/disk1/store1``:
+
+.. code-block:: console
+
+  # proxmox-backup-manager acl update /datastore/store1 DatastoreAdmin --userid john@pbs
+
+You can monitor the roles of each user using the following command:
+
+.. code-block:: console
+
+   # proxmox-backup-manager acl list
+   ┌──────────┬──────────────────┬───────────┬────────────────┐
+   │ ugid     │ path             │ propagate │ roleid         │
+   ╞══════════╪══════════════════╪═══════════╪════════════════╡
+   │ john@pbs │ /datastore/disk1 │         1 │ DatastoreAdmin │
+   └──────────┴──────────────────┴───────────┴────────────────┘
+
+A single user can be assigned multiple permission sets for different datastores.
+
+.. Note::
+  Naming convention is important here. For datastores on the host,
+  you must use the convention ``/datastore/{storename}``. For example, to set
+  permissions for a datastore mounted at ``/mnt/backup/disk4/store2``, you would use
+  ``/datastore/store2`` for the path. For remote stores, use the convention
+  ``/remote/{remote}/{storename}``, where ``{remote}`` signifies the name of the
+  remote (see `Remote` below) and ``{storename}`` is the name of the datastore on
+  the remote.

+//!
+//! * [`Username`]: an owned user name. Internally a `String`.

+//! * [`RealmRef`]: a borrowed realm (`str` equivalent).
+//! * [`Userid`]: an owned user id (`"user@realm"`). Note that this does not have a separate

+//!
+//! Note that `Username`s are not unique, therefore they do not implement `Eq` and cannot be
+//! compared directly. If a direct comparison is really required, they can be compared as strings
+//! via the `as_str()` method. [`Realm`]s and [`Userid`]s on the other hand can be compared with
