Backups

All backups can be found in the /backup directory on the UIs. The /user, /group, /software & /ice3 are backed up every day to a secondary ceph storage cluster, in case our production cluster goes down.


!! NOTE: /pnfs is NOT backed-up, as it is a massive storage !!


/user, /group, /software & /ice3

Our ceph server allows us to do regular snapshots, they can be found in /backup/$DATE/{user,group,software,ice3}:

  • There is one done every 24 hours at 9am, we keep the last seven of those (so a complete week), eg:
auto:daily-storage-2018-08-02-03:00
  • We also have one snapshot done every Saturday at midnight, and keep the last 4 of them (so a month), eg:
auto:weekly-storage-2018-07-14-00:00

Additionnaly, the /user, /group, /software & /ice3 are backed up every day to a secondary machine, in case our main fileserver goes down.
