backup.sugarlabs.org

This is the main backup server for all Sugarlabs Machines. The hostname backup.sugarlabs.org is an alias for owl.laptop.org, a machine hosted at OLPC.

Backup account:

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

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.

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.

Restoring files from duplicity 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
