Comment on How often do you run backups on your system?

Proxmox servers are mirrored zpools, not that RAID is a backup. Replication between Proxmox servers every 15 minutes for HA guests, hourly for less critical guests. Full backups with PBS at 5AM and 7PM, 2 sets apiece with one set that goes off site and is rotated weekly. Differential replication every day to zfs.rent. I keep 30 dailies, 4 weeklys, 24 monthly and infinite annuals.
Periodic test restores of all backups at various granularities at least monthly or whenever I’m bored or fuck something up.

This is very similar to how I run mine, except that I use Ceph instead of ZFS. Nightly backups of the CephFS data with Duplicati, followed by staggered nightly backups for all VMs and containers to a PBS VM on a the NAS. File backups from unraid get sent up to CrashPlan.
Slightly fewer retention points to cut down on overall storage, and a similar test pattern.

I would like to play with ceph but I don’t have a lot of spare equipment anymore, and I understand ZFS pretty well, and trust it. Maybe the next cluster upgrade if I ever do another one.
And I have an almost unhealthy paranoia after see so many shitshows in my career, so having a pile of copies just helps me sleep at night. PBS dedup is pretty damn good so it’s not much extra to keep a lot of copies.
