My understanding is that both zfs and btrfs on linux are fairly experimental. The codebase for zfs is much more mature in general, though its integration on Linux is recent. The codebase for btrfs changes rapidly, with quite a few regressions. I've never irrecoverably lost data on btrfs, but it wouldn't be my first choice for a production environment unless I basically did my own QC on the kernel. However, all my important data is on btrfs nonetheless (with a full backup to ext4 daily right now). --=20 Rich
