+Proxmox Backup Server
+---------------------
+
+In order to back up your {pmg} configuration on a Proxmox Backup
+Server, you first need to configure the instance as a backup 'remote'.
+You can then directly create and restore backups, as well as create a
+scheduled 'backup job' to run regular backups.

+Remotes

+endif::manvolnum[]
+
+
+A Proxmox Backup Server remote can be configured using the 'Proxmox Backup
+Server' panel in the 'Backup/Restore' menu of the GUI, or by using the
+`remote` subcommand of `pmgbackup`.
+
+NOTE: You can use API Tokens in place of a username/password combination.
+
+.Example addition of a Proxmox Backup Server remote with id 'archive'.
+----
+# pmgbackup proxmox-backup remote add archive --datastore big --server backup.proxmox.com --user 'pmgbackup@pbs!token' --password --fingerprint 09:54:ef:..snip..:88:af:47:fe:4c:3b:cf:8b:26:88:0b:4e:3c:b2
+Enter new password: ******
+Retype new password: ******
+----
+
+The fingerprint is optional, if the certificate of the Proxmox Backup Server
+remote is signed by a CA trusted by {pmg}.
+
+Additionally, you can configure `prune-settings` for each remote, giving you
+flexible control over how many backups should be stored on the Proxmox Backup
+Server over a specific period of time.
+
+.Setting the prune options for the Proxmox Backup Server remote with id 'archive'.
+----
+# pmgbackup remote set archive --keep-last 3 --keep-daily 14 --keep-weekly 8 --keep-monthly 12 --keep-yearly 7
+----
+
+If prune settings are configured, the backup-group of {pmg} is pruned
+automatically after each successful backup.
+
+The `notify` and `include-statistics` settings of a remote define the defaults
+for notifications and whether to include the statistic database in backups.
+They are also used for xref:pmgbackup_pbs_schedule[scheduled backups].
+
+The public settings are stored in `/etc/pmg/pbs/pbs.conf`. Sensitive settings,
+like passwords are stored in individual files named after the remote inside
+`/etc/pmg/pbs/`:
+
+.Configuration Example (`/etc/pmg/pbs/pbs.conf`)
+----

+ datastore big

+
+You can remove a particular snapshot by using the `forget` subcommand. This
+allows the Proxmox Backup Server to remove it during garbage collection.
+

+
+TIP: You can configure and access all backup-related functionality on
+both the web interface and the command line interface.
+
+[[pmgbackup_pbs_schedule]]
+Scheduled Backups
+^^^^^^^^^^^^^^^^^
+
+You can create a `Schedule` for each remote, to periodically create backups of
+your {pmg} - for example to run a daily backup at 03:50:00 with a randomized
+delay of 15 minutes each day:
+
+----
+# pmgbackup proxmox-backup job create archive --schedule '*-*-* 03:50:00' --delay '15 minutes'
+----
+
+The randomized delay can help to prevent load-peaks on the backup server, if
+you have multiple backups which should all start around the same time.
+The schedules are `systemd.timer` units. See the `systemd.time(7)` man page for
+details on the time specification used.
