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, 12 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.
Yes, former sysadmin.
