It's unnoticeable when you don't reevaluate your choices. Once you get into the habit of automatic snapshots, ext4's lack of snapshotting is very noticeable.

- MacsHeadroom 3y agoI'm not GP, but I'm curious. What am I missing out on? When would I benefit from having a snapshot on say my laptop?
- nubinetwork 3y agoRolling back or cloning the snapshot lets you get back deleted files, or reverting a bad update or config change... The snapshot is also a point in time to derive backups from, and usually costs nothing to make, as opposed to making a dd image of the disk, or tarballing everything, etc. Whether you think you need those is debatable, but it's quick and easy enough, works for me.
- rhn_mk1 3y agoOne thing the sibling did not mention is you can use btrfs send/receive to create dead easy, fast, and simple to restore incremental backups.
- _piif 3y agoI've lost track of the amount of times I accidentally deleted a file I shouldn't have or messed up a git project in a way it'd have taken ages to untangle, said oops, remembered I have hourly snapper snapshots set up and just copied the previous state over. It's been a massive time- and occasionally lifesaver for me.
- graypegg 3y agoYou know, that's very convincing actually! I'm obviously missing out, I'll need to mess around with it more.
- _piif 3y agoIf you decide to dive into it depending on your filesystem of choice I can recommend either Sanoid [0] and httm [1] for ZFS or Snapper [2] for BTRFS as automatic snapshot solutions. Good luck with your endeavors!
