Locations

• /backup on treehouse.sugarlabs.org (for sunjammer's daily filesystem backups)
• backup.sugarlabs.org (all the other systems)
• /backup on sunjammer.sugarlabs.org (for sunjammer databases: ldap, mysql and pgsql)

backup.sugarlabs.org

This is the main backup server for all Sugarlabs Machines

Backup account: sugarbackup@backup.sugarlabs.org:/home/sugarbackup/

(backup.sugarlabs.org is an alias for owl.laptop.org)

Sunjammer

Machine/sunjammer's filesystem is being backed up on Machine/treehouse using rsync + 7 days of history with hard links.

The MySQL, PostgreSQL and LDAP databases are being backed up daily on backup.sugarlabs.org, encrypted with gpg. TODO: at the moment, we don't have a script to cleanup old backups.

Restore Backups

To restore a backup try something like:

  duplicity restore -t 7D --restore-time <yyyy/mm/dd --file-to-restore <source/path/to/restore/from>  scp://sugarbackup@backup.sugarlabs.org/backup/<machine.sugarlabs.org>  </destination/path/to/restore/to>

• Replace <> with your values

Example:

  duplicity restore -t 7D --restore-time 2000/01/01 --file-to-restore var/lib/mysql/wordpress  scp://sugarbackup@backup.sugarlabs.org/backup/sunjammer.sugarlabs.org  /home/bernie/restore/wordpress

the --restore-time is a workaround for a bug in duplicity when restoring backups in the past
