We take LDAP and Kerberos backups twice daily. Backups on auth1 occur at 4am and on auth2 they occur at 4pm. On each machine, backups are stored in /backup/{ldap,krb5} (in the case of auth1, this is /backup exported from the NetApp).
Miscellaneous backups (including backups of home directories for expired accounts) are stored in /users/backup (accessible on any system that NFS-mounts /users).
/users Backup
/users primary is held on ranch, whilst it's backup is held on tequila via incremental zfs snapshots
On Tequila I made a dedicated destination dataset called backup/csc0_backups (backups is a big pool);
zfs create backup/csc0_backups
Then on ranch I ran a snapshot, and sent it over;
zfs snapshot -r csc0@base
zfs send -R csc0@base | ssh root@tequila zfs recv -F backup/csc0_backups
In the future we need to setup incremental sends on ranch
zfs snapshot -r csc0@snap_$(date +%Y%m%d)
zfs send -R -i csc0@base csc0@snap_$(date +%Y%m%d) | ssh root@tequila zfs recv -F backup/csc0_backups
MySQL
We don't currently backup MySQL. See the historical version of this page for previous backup strategy.
