I gotcha:
- Btrfs
- BTree File System
- A Copy on White file system that supports snapshots, supported mostly by
- BTree File System
- ZFS
- Zetabyte File System
- Copy on Write File System. Less flexible than BTRFS but generally more robust and stable. Better compression in my experience than BTRFS. Out of Kernel Linux support and native FreeBSD.
- Zetabyte File System
- HFS+
- what Mac uses, I have no clue about this. some Copy on Write stuff.
- NTFS
- Windows File System
- From what I know, no compression or COW
- In my experience less stable than ext4/ZFS but maybe it’s better nowadays.
Well that’s good to know because I had some terrible luck with it about a decade ago. Although I don’t think I would go back to windows, I just don’t need it for work anymore and it’s become far too complex.
I’ve also had pretty bad luck with BTRFS though, although it seems to have improved a lot in the past 3 years that I’ve been using it.
ZFS would be good but having to rebuild the kernel module is a pain in the ass because when it fails to build you’re unbootable (on root). I also don’t like how clones are dependant on parents, requires a lot of forethought when you’re trying to create a reproducible build on eg Gentoo.
