+  :align: right
+  :alt: Create a directory
+
+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).

+Network Management
+~~~~~~~~~~~~~~~~~~
+
+Proxmox Backup Server provides both a web interface and a command line tool for
+network configuration. You can find the configuration options in the web
+interface under the **Network Interfaces** section of the **Configuration** menu
+tree item. The command line tool is accessed via the ``network`` subcommand.
+These interfaces allow you to carry out some basic network management tasks,
+such as adding, configuring, and removing network interfaces.
+
+.. note:: Any changes made to the network configuration are not
+  applied, until you click on **Apply Configuration** or enter the ``network
+  reload`` command. This allows you to make many changes at once. It also allows
+  you to ensure that your changes are correct before applying them, as making a
+  mistake here can render the server inaccessible over the network.

+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 inaccessable 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,

+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 systemds 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

+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 synchroize 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.

+//! * [`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
