Backup and restore
Keep a backup before changing things, and restore it in one step if something goes wrong. PSM also takes a quick backup before it updates itself.
Everything is in main menu 17 (Backup):
| Option | What it does |
|---|---|
| Full backup (all components) | backs up the configuration of everything PSM manages |
| Selective backup | only the components you choose |
| Restore from backup | pick a backup to restore (main menu 18 (Restore) goes straight there) |
| List backups | see the backups you have |
| Enable / disable automatic backups | a full backup every day |
Backups are .tar.gz files in /opt/psm/backup/. A full backup from the command line:
bash
psm --backup-fullMoving to another server
Backups are for going back on the same server. To move your nodes to another server, use migration: it installs what the new server needs, rebuilds the services and rewrites subscription addresses, which is far less work than restoring a backup by hand.
