It seems like ZFS/Btrfs snapshots would do this.

amelius • Jun 25, 2023 • View on HN

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

amelius • May 14, 2017 • View on HN

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...
