I have been using it on external drives of my home machine (Backup and
media) for a few months now. No reported problems, one was converted
from ext4 which I found a very nice feature.

Be sure to check here for which versions are recommended by the btrfs people.


I've done a few non-scientific "tests" such as pulling the USB cable
while it's reading/writing and then letting fsck.btrfs sort things
out. Again no issues. I'm also using the snapshot feature along with
rsync as a form of backup.

Previously I used dirvish (+rsync) which achieves the same things
albeit via a nest of hardlinks in date ordered folders.

I will say that the ability to mount previous snapshots is pretty nifty.
