-Backup Management
-=================
-
-.. 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, 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.
-
-
-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.
-
-
-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.
-
-.. code-block:: console
-   :caption: Backup Snapshot Examples
-
-    vm/104/2019-10-09T08:01:06Z
-    host/elsa/2019-11-08T09:48:14Z
-
-As you can see, the time format is RFC3399_ with Coordinated
-Universal Time (UTC_, identified by the trailing *Z*).
-
-Backup Server Management
-------------------------
-
-The command line tool to configure and manage the backup server is called
-:command:`proxmox-backup-manager`.
-
-
-
-: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.
-
-.. 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
-~~~~~~~~~~~~~~~~~~~~~~~
-
-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:`Pruning <pruning>` and
-:ref:`garbage collection <garbage-collection>` can also be configured to run
-periodically based on a configured :term:`schedule` per datastore.
-
-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. │
-  └────────┴──────────────────────┴─────────────────────────────┘
-
-You can change settings of a datastore, for example to set a prune and garbage
-collection schedule or retention settings using ``update`` subcommand and view
-a datastore with the ``show`` subcommand:
-
-.. code-block:: console
-
-  # proxmox-backup-manager datastore update store1 --keep-last 7 --prune-schedule daily --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
- 545824 drwxr-x--- 2 backup backup 4.0K Jul  8 12:35 ffff

- ...
- 403180 drwxr-x--- 2 backup backup 4.0K Jul  8 12:35 000c
- 403179 drwxr-x--- 2 backup backup 4.0K Jul  8 12:35 000b
- 403177 drwxr-x--- 2 backup backup 4.0K Jul  8 12:35 000a
- 402530 drwxr-x--- 2 backup backup 4.0K Jul  8 12:35 0009

- 276490 drwxr-x--- 1 backup backup 1.1M Jul  8 12:35 .
-
-
-
-User Management
-~~~~~~~~~~~~~~~
-
-Proxmox Backup Server supports 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 need 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            │
-  ╞═════════════╪════════╪════════╪═══════════╪══════════╪════════════════╪════════════════════╡
-  │ root@pam    │      1 │        │           │          │                │ Superuser          │
-  └─────────────┴────────┴────────┴───────────┴──────────┴────────────────┴────────────────────┘
-
-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 options like ``--email`` or
-``--password``. 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.
-
-
-The resulting user list looks like this:
-
-.. code-block:: console
-
-  # proxmox-backup-manager user list
-  ┌──────────┬────────┬────────┬───────────┬──────────┬──────────────────┬──────────────────┐
-  │ userid   │ enable │ expire │ firstname │ lastname │ email            │ comment          │
-  ╞══════════╪════════╪════════╪═══════════╪══════════╪══════════════════╪══════════════════╡
-  │ john@pbs │      1 │        │ John      │ Smith    │ john@example.com │ An example user. │
-  ├──────────┼────────┼────────┼───────────┼──────────┼──────────────────┼──────────────────┤
-  │ root@pam │      1 │        │           │          │                  │ Superuser        │
-  └──────────┴────────┴────────┴───────────┴──────────┴──────────────────┴──────────────────┘
-
-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
-
-
-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.
-
-You can use the ``acl`` subcommand to manage and monitor user permissions. For
-example, the command below will add the user ``john@pbs`` as a
-**DatastoreAdmin** for the data store ``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 data stores.
-
-.. Note::
-  Naming convention is important here. For data stores on the host,
-  you must use the convention ``/datastore/{storename}``. For example, to set
-  permissions for a data store 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 data store on
-  the remote.
-
-: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`.
-

-Backup Client usage
--------------------
+Backup Client Usage
+===================
 
 The command line client is called :command:`proxmox-backup-client`.
 
 
 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 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.
 
+Here some examples of valid repositories and the real values

+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:
+

+======================== =============================  ===================================
+
+
+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.

+Backup is, and always has been, a central aspect of IT administration.
+The need to recover from data loss is fundamental and only increases with
+virtualization.
 
+For this reason, we've been shipping a backup tool with Proxmox VE, from the
+beginning. This tool is called ``vzdump`` and is able to make
+consistent snapshots of running LXC containers and KVM virtual
+machines.
+
+However, ``vzdump`` only allows for full backups. While this is fine
+for small backups, it becomes a burden for users with large VMs. Both
+backup duration and storage usage are too high for this case, especially
+for users who want to keep many backups of the same VMs. To solve these
+problems, we needed to offer deduplication and incremental backups.
+
+Back in October 2018, development started. We investigated
+several technologies and frameworks and finally decided to use
+:term:`Rust` as the implementation language, in order to provide high speed and
+memory efficiency. The 2018-edition of Rust seemed promising for our
+requirements.
+
+In July 2020, we released the first beta version of Proxmox Backup
+Server, followed by the first stable version in November 2020. With support for
+incremental, fully deduplicated backups, Proxmox Backup significantly reduces
+network load and saves valuable storage space.

+`Proxmox VE`_ Integration
+-------------------------
+
+You need to define a new storage with type 'pbs' on your `Proxmox VE`_
+node. The following example uses ``store2`` as storage name, and
+assumes the server address is ``localhost``, and you want to connect
+as ``user1@pbs``.
+
+.. code-block:: console
+
+  # pvesm add pbs store2 --server localhost --datastore store2
+  # pvesm set store2 --username user1@pbs --password <secret>
+
+.. note:: If you would rather not pass your password as plain text, you can pass
+  the ``--password`` parameter, without any arguments. This will cause the
+  program to prompt you for a password upon entering the command.
+
+If your backup server uses a self signed certificate, you need to add
+the certificate fingerprint to the configuration. You can get the
+fingerprint by running the following command on the backup server:
+
+.. 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
+
+Please add that fingerprint to your configuration to establish a trust
+relationship:
+
+.. code-block:: console
+
+  # pvesm set store2 --fingerprint  64:d3:ff:3a:50:38:53:5a:9b:f7:50:...:ab:fe
+
+After that you should be able to see storage status with:
+
+.. code-block:: console
+
+  # pvesm status --storage store2
+  Name             Type     Status           Total            Used       Available        %

+
+Having added the PBS datastore to `Proxmox VE`_, you can backup VMs and
+containers in the same way you would for any other storage device within the
+environment (see `PVE Admin Guide: Backup and Restore
+<https://pve.proxmox.com/pve-docs/pve-admin-guide.html#chapter_vzdump>`_.

+
+You can create an ``ext4`` or ``xfs`` filesystem on a disk using ``fs
+create``, or by navigating to **Administration -> Disks -> Directory** in the
+web interface and creating one from there. The following command creates an
+``ext4`` filesystem and passes the ``--add-datastore`` parameter, in order to
+automatically create a datastore on the disk (in this case ``sdd``). This will
+create a datastore at the location ``/mnt/datastore/store1``:
+
+.. code-block:: console
+
+  # proxmox-backup-manager disk fs create store1 --disk sdd --filesystem ext4 --add-datastore true
+
+.. image:: images/screenshots/pbs-gui-disks-zfs-create.png
+  :align: right
+  :alt: Create ZFS
+
+You can also create a ``zpool`` with various raid levels from **Administration
+-> Disks -> Zpool** in the web interface, or by using ``zpool create``. The command
+below creates a mirrored ``zpool`` using two disks (``sdb`` & ``sdc``) and
+mounts it on the root directory (default):
+
+.. code-block:: console
+
+  # proxmox-backup-manager disk zpool create zpool1 --devices sdb,sdc --raidlevel mirror
+
+.. note:: You can also pass the ``--add-datastore`` parameter here, to automatically
+  create a datastore from the disk.
+
+You can use ``disk fs list`` and ``disk zpool list`` to keep track of your
+filesystems and zpools respectively.
+
+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
+display S.M.A.R.T. attributes from the web interface or by using the command:
+
+.. code-block:: console
+
+  # proxmox-backup-manager disk smart-attributes sdX
+
+.. 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
+    redundant ZFS setup (ZFS is not compatible with a hardware RAID
+    controller).
+
+* Backup storage:
+
+  * Use only SSDs, for best results
+  * If HDDs are used: Using a metadata cache is highly recommended, for example,
+    add a ZFS :ref:`special device mirror <local_zfs_special_device>`.
+
+* Redundant Multi-GBit/s network interface cards (NICs)
+
+
+Supported Web Browsers for Accessing the Web Interface
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To access the server's web-based user interface, we recommend using one of the
+following browsers:
+
+* Firefox, a release from the current year, or the latest Extended Support Release
+* Chrome, a release from the current year
+* Microsoft's currently supported version of Edge
+* Safari, a release from the current year

+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.
+
+.. code-block:: console
+   :caption: Backup Snapshot Examples
+
+    vm/104/2019-10-09T08:01:06Z
+    host/elsa/2019-11-08T09:48:14Z

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

+
+Proxmox Backup Server supports 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 need 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. User configuration information is stored in the file
+``/etc/proxmox-backup/user.cfg``. You can use the
+``proxmox-backup-manager`` command line tool to list or manipulate

+  :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.

+//! # Locking
+//!
+//! Since PBS allows multiple potentially interfering operations at the
+//! same time (e.g. garbage collect, prune, multiple backup creations
+//! (only in seperate groups), forget, ...), these need to lock against
+//! each other in certain scenarios. There is no overarching global lock
+//! though, instead always the finest grained lock possible is used,
+//! because running these operations concurrently is treated as a feature
+//! on its own.
+//!
+//! ## Inter-process Locking
+//!
+//! We need to be able to restart the proxmox-backup service daemons, so
+//! that we can update the software without rebooting the host. But such
+//! restarts must not abort running backup jobs, so we need to keep the
+//! old service running until those jobs are finished. This implies that
+//! we need some kind of locking for modifying chunks and indices in the
+//! ChunkStore.
+//!
+//! Please note that it is perfectly valid to have multiple
+//! parallel ChunkStore writers, even when they write the same chunk
+//! (because the chunk would have the same name and the same data, and
+//! writes are completed atomically via a rename). The only problem is
+//! garbage collection, because we need to avoid deleting chunks which are
+//! still referenced.
+//!
+//! To do this we use the
+//! [ProcessLocker](../tools/struct.ProcessLocker.html).
+//!
+//! ### ChunkStore-wide
+//!
+//! * Create Index Files:
+//!
+//!   Acquire shared lock for ChunkStore.
+//!
+//!   Note: When creating .idx files, we create a temporary .tmp file,
+//!   then do an atomic rename.
+//!
+//! * Garbage Collect:
+//!
+//!   Acquire exclusive lock for ChunkStore. If we have
+//!   already a shared lock for the ChunkStore, try to upgrade that
+//!   lock.
+//!
+//! Exclusive locks only work _between processes_. It is valid to have an
+//! exclusive and one or more shared locks held within one process. Writing
+//! chunks within one process is synchronized using the gc_mutex.
+//!
+//! On server restart, we stop any running GC in the old process to avoid
+//! having the exclusive lock held for too long.
+//!
+//! ## Locking table
+//!
+//! Below table shows all operations that play a role in locking, and which
+//! mechanisms are used to make their concurrent usage safe.
