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)
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
