Backups

User space on T2B

The /user, /group, /software & /ice3 are backed up every day to a secondary ceph storage cluster, in case our production cluster goes down.
Backups can be found in /backup/$DATE/{user,group,software,ice3}:

  • There is one done every day at 8.30am, we keep the last seven of those (so a complete week), eg:
scheduled-2024-02-04-08_30_00_UTC
  • We also keep the last 4 Sunday snapshots, equivalent to a month.
  • All backups are READ-ONLY, so extract the files you want from them into your personal directory

Mass Storage

/pnfs is NOT backed-up, as it is a massive storage.
