Hello everyone. I’m going to build a new PC soon and I’m trying to maximize its reliability all I can. I’m using Debian Bookworm. I have a 1TB M2 SSD to boot on and a 4TB SATA SSD for storage. My goal is for the computer to last at least 10 years. It’s for personal use and work, playing games, making games, programming, drawing, 3d modelling etc.

I’ve been reading on filesystems and it seems like the best ones to preserve data if anything is lost or corrupted or went through a power outage are BTRFS and ZFS. However I’ve also read they have stability issues, unlike Ext4. It seems like a tradeoff then?

I’ve read that most of BTRFS’s stability issues come from trying to do RAID5/6 on it, which I’ll never do. Is everything else good enough? ZFS’s stability issues seem to mostly come from it having out-of-tree kernel modules, but how much of a problem is this in real-life use?

So far I’ve been thinking of using BTRFS for the boot drive and ZFS for the storage drive. But maybe it’s better to use BTRFS for both? I’ll of course keep backups but I would still like to ensure I’ll have to deal with stuff breaking as little as possible.

Thank you in advance for the advice.

    OpenSUSE, both Leap and Tumbleweed, use btrfs by default. Do you switch those to xfs during installation?

    I’ve had btrfs snapshots pull me out of the fire multiple times on my home machines, but I don’t fully trust any file system at all, so I rsync stuff to two local network destinations and an off-site location as well. Those, too, have come in handy.

      Yep, sure do. I’ve no real benefit for the features it adds, or I’m completely ignorant to the benefits is probably more accurate :)

      For the things you’ve mentioned it is useful. I think the main thing I’ve been warned to never do with BTRFS is use it for RAID and to use md under it instead. That said, that could be old info and it may be fixed now.
