Backup

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.
