@dirtytigerx I'd like to give thanks to my lord and savior, ZFS, at least once a month. Between the redundancy, snapshotting, and replication, it makes life so much better. That said, I probably don't need 3 cases with a total of 18 + 24 + 12 bays.
@dirtytigerx it's mostly one machine that keeps moving to a new build. First version was from like 2006ish, then redone in 2012?, and the newest from last year. But yeah, my offsite backups for personal stuff are pretty slimmed down to just the essentials.
