== Backup Strategy ==

* '''Cluster head node''':[[br]]
Results are stored on a RAID5 storage element. [[br]]
No external backup.
* '''Cluster compute nodes''':[[br]]
Do not contain sensible data except operating system.[[br]]
No external backup.
* '''Trac''':[[br]]
Hosts Wiki pages, SVN repository, Ticketing system, etc.[[br]]
Backup to tape system (scripts on ''much.cs.nott.ac.uk''), incremental from Monday to Friday, full dump once a week:

||'''Partition'''||'''Day''' ||
||/ ||every Tuesday ||
||/home/ ||every Wednesday ||
||/usr/local/ ||every Monday ||
