Hearing roughly a decade of successful use, especially on systems with constrained resources, certainly makes me lean further towards btrfs.
its RAID ≠ 0/1/10 are buggy, but 0/1/10 are considered reliable.
btrfs has been solid and done everything I could want. It was a huge upgrade from mdadm and lvm
@ikidd@lemmy.world said that btrfs is poor at software RAID. I’ll do a little research in to how it fares for RAID 1 vs mdadm. I don’t see any reason I couldn’t do mdadm>luks>btrfs if that’s the better choice. But if btrfs is reliable and with comparable performance, I’d certainly rather do that.
I wasn’t familiar with timeshift so I took a look at it. My primary use case for snapshots is to take one before updates. So I can load from the snapshot if there’s issues. It doesn’t look like using it with ext4 would fulfill this use-case. But it looks like it also supports btrfs snapshots so could be useful as a UI to configure that.
