zfs or bust. If you are not using zfs for your long term storage and backups, you might want to consider what exactly you are doing and why you aren’t paying someone else to make sure your 1s stay as 1s and 0s as 0s.

To be fair, ZFS isn't the only game in town. Depending on what you're doing, gluster, ceph, minio, restic/borg/etc. may prove sufficient. I like ZFS, don't get me wrong, but if the goal is bitrot protection there are a number of different tools to solve it at different places in the stack.

  For a NAS, I don’t think backup tools with checksumming would be sufficient. I also am not a fan of them as the only tool to prevent bitrot. If borg detects that a backup is corrupt, my option is what? To ditch that backup? zfs can not only detect it, but also recover from it. That’s not something that most tools can do. To be fair, I don’t know about the capabilities of gluster, ceph, and minio.

btrfs has checksums to prevent bitrot.

  Has it gotten less crash crash eat your data stash? Last I checked, distros were putting it into their install options while it was still happy to crash the FS with major data loss. I haven’t checked on whether it was worth it since.

    It's been the default OS for opensuse for at least afew years. I've been using it on root filesystems and data volumes with no problems. I was backing up to a 1TB btrfs volume but it filled up with snapshots and cleaning them didn't cause any problems. I've since moved to a 4TB drive and I rsync another drive to it weekly and take a snapshot. I've had no issues. https://en.opensuse.org/SDB:BTRFS https://en.opensuse.org/SDB:BTRFS edit: I've had a couple hard crashes in this period. My homeserver's power button attracts little fingers.

    Synology are using it on many of their NAS units, alternative being ext4fs.
