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 used a script that did everything for me, so I’m not 100 % sure. But as far as I know you enable the feature at mount time and then every time you copy something only a reference is copied until you actually do a change to the new or old file.

    For everything else a cronjob runs every week or so to search for unnecessary duplicates.
