spoiler: he has 10 minutes incremental backups.

  Its "backups" join "zfs makes snapshots easy" join "snapshots make incremental backups easy" join "backups on device aren't a backup" join "I had off-device backups" which reduces to "I had backups" indeed. 3-2-1 forever!

    > "backups on device aren't a backup" That wasn't part of the article. It was a single drive failure, so RAID would have done fine.

      Yes, RAID will get you over some failures. But, it still isn't a backup. Backup is what gets you over corrupted RAID, loss of both sides of the mirror stripe, entire disk failure when its not RAID. What he does is run zrep to make a backup. it covers his needs. ZFS snapshot by itself is only transitionally a "backup" for the immediacy of change, it's the least safe form of backup if it remains on the same logical drive structure.

        > Yes, RAID will get you over some failures. But, it still isn't a backup. backups also can fail, that zrep can start failing after some os/kernel update without notifying owner. The question is in probabilities of failures, I kinda would trust industrial raid more than some custom made hobby solution.
