we should be able to just modify how many snapshots we keep - it's set in /opt/sown/backup/backup/config.py
- https://github.com/sown/backup/blob/master/backup/config.example.py#L5
I guess the other option is we make it smarter, so it keeps exactly enough snapshots to keep our disk usage at a certain level
one to discuss tomorrow
I've reduced our retention of monthly snapshots on backup2 to 12 months (was previously 24), let's see how it goes tonight
@TimStallard Also updated backup3 to have the schedule a few days later. Both backup servers seem to be keeping a reasonably stable level of disk usage since this change in the 70-75% range.
I think this can be resolved. Although we should keep and eye on this to make sure it does not creep up too much over time.
Although there is still capacity to remove old style backups to free space on the backup servers for a while yet. We need to look at the cycling of ZFS snapshots so that disk usage on backup servers stays fairly constant.
