You know, ZFS, ButterFS (btrfs…its actually “better” right?), and I’m sure more.

I think I have ext4 on my home computer I installed ubuntu on 5 years ago. How does the choice of file system play a role? Is that old hat now? Surely something like ext4 has its place.

I see a lot of talk around filesystems but Ive never found a great resource that distiguishes them at a level that assumes I dont know much. Can anyone give some insight on how file systems work and why these new filesystems, that appear to be highlights and selling points in most distros, are better than older ones?

Edit: and since we are talking about filesystems, it might be nice to describe or mention how concepts like RAID or LUKS are related.

    I suppose it depends on how much stuff you have, doing a full back up of my home every week is too time consuming to be practical but takes a couple of minutes with this method.

    Keeping multiple past snapshots is overkill for me but I do it because I can, more-or-less. It would be useful if I accidentally delete a file and only remember it months later.
