It seems like ZFS/Btrfs snapshots would do this.

Or simply use a filesystem that allows snapshots.

Can't ZFS do these kinds of things with snapshot?

viraptor Jan 12, 2026 View on HN

Sure you can. Filesystem snapshotting is available on all OSes now.

seniorivn Sep 15, 2021 View on HN

you can use fs snapshots and backups

Perhaps a snapshotting filesystem could help too.

If you run ZFS, you can use ZFS snapshots.

danarmak Jun 27, 2017 View on HN

Use a filesystem that lets you take regular snapshots, like zfs.

j1elo Aug 22, 2021 View on HN

Similar to making a ZFS snapshot, maybe?

If only it had a native filesystem with snapshotting capability...
