[[chapter_pmgbackup]] ifdef::manvolnum[] pmgbackup(1) ============ :pmg-toplevel: NAME ---- pmgbackup - Proxmox Mail Gateway Backup and Restore Utility SYNOPSIS -------- include::pmgbackup.1-synopsis.adoc[] DESCRIPTION ----------- endif::manvolnum[] ifndef::manvolnum[] Backup and Restore ================== :pmg-toplevel: endif::manvolnum[] ifndef::manvolnum[] [thumbnail="screenshot/pmg-gui-backup.png", big=1] endif::manvolnum[] {pmg} includes the ability to back up and restore the configuration. This includes the complete config from `/etc/pmg/`, the mail filter rules, and the statistic database. NOTE: The backup does not include the network setup, nor does it contain mail data from the postfix queue or the spam and virus quarantines. Backups can be created locally or stored on a https://www.proxmox.com/en/proxmox-backup-server/overview[Proxmox Backup Server] instance. Local Backups ------------- You can create a backup by simply pressing the 'Backup' button in the 'Local Backup/Restore' tab on the GUI, or by using the command-line interface: ---- # pmgbackup backup starting backup to: /var/lib/pmg/backup/pmg-backup_2018_01_04_5A4E0436.tgz backup finished ---- Local backups are stored inside directory `/var/lib/pmg/backup/`. It is usually best to mount a remote file system to that directory, so that the resulting backups gets stored remotely. You can list the contents of that directory with: ---- # pmgbackup list .... pmg-backup_2017_11_10_5A05D4B9.tgz 17012 pmg-backup_2017_11_13_5A09676A.tgz 16831 pmg-backup_2018_01_04_5A4E0436.tgz 21514 ---- Restores are also possible using the GUI or command line, and you can select which parts you want to restore: System Configuration:: Basically the contents of `/etc/pmg/`. Rule Database:: The mail filter rule database. Statistic:: All statistical data. For example, you can selectively restore the mail filter rules from an older backup: ---- # pmgbackup restore --filename pmg-backup_2018_01_04_5A4E0436.tgz --database starting restore: /var/lib/pmg/backup/pmg-backup_2018_01_04_5A4E0436.tgz config_backup.tar: OK Proxmox_ruledb.sql: OK Proxmox_statdb.sql: OK version.txt: OK Destroy existing rule database Create new database run analyze to speed up database queries Analyzing/Upgrading existing Databases...done restore finished ---- [[pmgbackup_pbs]] 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. [[pmgbackup_pbs_remotes]] Remotes ~~~~~~~ ifndef::manvolnum[] [thumbnail="screenshot/pmg-gui-pbs-remote.png"] 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`) ---- pbs: archive datastore big server backup.proxmox.com fingerprint 09:54:ef:..snip..:88:af:47:fe:4c:3b:cf:8b:26:88:0b:4e:3c:b2 keep-daily 30 keep-last 5 keep-monthly 3 keep-yearly 5 username pmgbackup@pbs!token ---- [[pmgbackup_pbs_jobs]] Backup Jobs ~~~~~~~~~~~ ifndef::manvolnum[] [thumbnail="screenshot/pmg-gui-pbs-backup.png", big=1] endif::manvolnum[] With a configured remote, you can create backups using the GUI or the `proxmox-backup backup` subcommand of the `pmgbackup` CLI tool. .Creating a new backup on the Proxmox Backup Server remote with id 'archive'. ---- # pmgbackup proxmox-backup backup archive starting update of current backup state Starting backup: host/pmg/2020-11-16T16:38:39Z Client name: pmg Starting backup protocol: Mon Nov 16 16:38:39 2020 Upload directory '/var/lib/pmg/backup/current' to 'pmgbackup@pbs!token@backup.proxmox.com:8007:local' as pmgbackup.pxar.didx pmgbackup.pxar: had to upload 188.33 KiB of 188.33 KiB in 0.00s, average speed 162.33 MiB/s). Uploaded backup catalog (145 B) Duration: 0.06s End Time: Mon Nov 16 16:38:39 2020 backup finished starting prune of host/pmg prune finished ---- For restoring, you can optionally select a particular backup-snapshot to return to the state of configuration and rules at that time. From the command line, you can get a list of available backup snapshots using the `proxmox-backup list` subcommand: .Listing available backups from the Proxmox Backup Server remote with id 'archive'. ---- # pmgbackup proxmox-backup list archive ┌────────────┬──────────────────────┬────────┐ │ backup-id │ backup-time │ size │ ╞════════════╪══════════════════════╪════════╡ │ pmg │ 2020-11-16T14:03:04Z │ 121910 │ ├────────────┼──────────────────────┼────────┤ ... └────────────┴──────────────────────┴────────┘ ---- .Restoring a specific backup snapshot ---- # pmgbackup proxmox-backup restore archive pmg 2020-11-16T14:03:04Z starting restore of host/pmg/2020-11-16T14:03:04Z from backup ..snip.. restore finished ---- You can remove a particular snapshot by using the `forget` subcommand. This allows the Proxmox Backup Server to remove it during garbage collection. ---- # pmgbackup proxmox-backup forget archive pmg 2020-11-16T14:03:04Z ---- 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. ifdef::manvolnum[] include::pmg-copyright.adoc[] endif::manvolnum[]
