− | This is the main backup script for all [[Machine|Sugar Labs Machines]]. It's a minimalist script based on rsync and keeps a history of N days using hard-links. While it's very very simple, wizbackup gets the job done and has the added benefit of not requiring any tools to read or restore a backup. The advantage over similar backup solution is that backups are just plain filesystem snapashots of the source machines; the main disadvantage is poor performance with large files which change often, such as logs or databases (my solution is to exclude these and backup the data using ad-hoc methods, such as SQL dumps). | + | This is the main backup script for all [[Machine|Sugar Labs Machines]].

− | To restore a backup try something like:
| |
− |
| |
− | duplicity restore -t 7D --file-to-restore <source/path/to/restore/from> scp://sugarbackup@backup.sugarlabs.org/backup/<machine.sugarlabs.org> </destination/path/to/restore/to>

− | Example:
| |
− |
| |
− | duplicity restore -t 7D --file-to-restore var/lib/mysql/wordpress scp://sugarbackup@backup.sugarlabs.org/backup/sunjammer.sugarlabs.org /home/bernie/restore/wordpress
