Backups

All backups can be found in the /backup directory on the UIs and WNs.


/user & /group

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

  • There is one done every 24 hours at 3am, 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 is backed up every day to a secondary machine, in case our main fileserver goes down.

/data & /software

Our zfs server allows us to do regular snapshots, they can be found in /backup/data/$SNAPSHOT_ID/{software,data}:

  • There is one done every 24 hours at 10 PM, we keep the last seven of those (so a complete week), eg:
  • Last snapshot = daily.0
  • The previous one = daily.1
  • etc.

/ice3

Our zfs server allows us to do regular snapshots, they can be found in /backup/ice3/$SNAPSHOT_ID:

  • There is one done every 24 hours at 10 PM, we keep the last seven of those (so a complete week), eg:
  • Last snapshot = daily.0
  • The previous one = daily.1
  • etc.

Additionnaly, the /ice3 is backed up every day to a secondary machine, in case our main fileserver goes down.
