I've got a 6TB btrfs array (two 3TB drives in a RAID 0). It's
about 2/3 full and has lots of snapshots. I've written a
script that runs through the snapshots and copies the data
efficiently (rsync --inplace --no-whole-file) from the main
6TB array to a backup
Hi folks.

No, btrfs send is exactly what you need. Using dd is slow because it
copies unused blocks, and requires the source fs be unmounted and the
destination be an empty partition. rsync is slow because it can't take
advantage of the btrfs tree to quickly locate the files (or parts of
them) that have

Hi everyone,
The for-linus branch of the btrfs repository:
git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus
Has a few more fixes. The most notable here are two more patches from
Alexandre's batch of allocator fixes. The other two fix corner cases in
the state code
Which kernel is this? This looks like one I recently fixed.

As soon as there's something that can be tested, you'll find it on this list.
Great, I'd love to try it. I spent a lot of time with ZFS and the zfs
send/recv functionality was very convenient.
Meanwhile, does anyone know how I can change the UUID of a btrfs partition or

Hi Chris,
This was on 3.2-rc2 but I tried with rc4 and it segfaulted again. I
think the traces were the same but I've rebooted and can't say for

Sure. It's a little raw, and makes some assumptions about my environment, but
it does the job other than the fact that it takes weeks to run. :)

That's usually a REALLY bad sign.
