+

+  :align: right

+
+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

+  :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 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

+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

+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:
+
+=================================  ==============================
+Value                              Syntax
+=================================  ==============================

+
+
+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 |
++=======================+====================+===============+============+====================+
+|Proxmox Backup 1.x     | Debian 10 (Buster) | tba           | tba        | tba                |
++-----------------------+--------------------+---------------+------------+--------------------+
+
+
+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.
