I've never actually tried BTRFS, there were a few too many "it loses all your data" bugs in the early days, and I was already using ZFS by then anyway. ZFS has more than it's fair share of problems, but I'm pretty confident my data is safe, and it has the same upsides as BTRFS. I'm looking forward to seeing how BCachefs works now it's in kernel, and I really want to compare all three under real workloads.
Ooh, I've never heard of bcachefs, sounds exciting! I see it supports encryption natively, which btrfs doesn't. Pretty cool!
Personally I've never had any issues with btrfs, but I did start using it only a couple years ago, when it was already stable. Makes sense that you'd stick with zfs tho, if that's what you're used to.
There’s a whole bunch of “it loses all your data” bugs in OpenZFS too, ironically, although it’s way way less fragile than btrfs in general.
That said, the latter is pretty much solid too, unless you do raid5-like things.
Yeah, I know there was one a while back, and if you don't use ECC RAM, given enough time, it will eat your data as it tries to correct checksum errors due to memory corruption. That's why we keep backups, right. Right?
I tend to assume that every storage system will eventually lose data, so having multiple copies is vital.
