~~Backup account:~~

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).

The `wizbackup-driver` script runs daily on the backup servers from `/etc/cron.daily/wizbackup`.

~~sugarbackup@~~backup.~~sugarlabs~~.~~org:/home/sugarbackup/~~

It reads a list of hostnames to backup from `/backup/HOSTS/<machine-group-name>` and an optional list of files exclusions from `/backup/EXCLUDES`.

~~We use~~ the ~~script system~~-~~full~~-backup ~~to perform the~~ daily ~~backups with duplicity~~. ~~Each~~ machine backup ~~is encrypted with a different password. If you need a password, ask [[User:Bernie]]~~.
