Thanks for getting back to me mate!

My test environment is:
root@Ubuntu-14:~/btrfs/btrfs-progs# uname -a
Linux Ubuntu-14 3.14.1-031401-generic #201404141220 SMP Mon Apr 14
16:21:48 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

root@Ubuntu-14:~/btrfs/btrfs-progs# which btrfs
/usr/local/bin/btrfs
root@Ubuntu-14:~/btrfs/btrfs-progs# btrfs --version
Btrfs v3.14.1

I read so much about BtrFS that I mistaked Bedup with Duperemove.
Duperemove is actually what I am testing.

I also plan on testing SDFS - opendedup again! They have some
development since the last time I tried,  Not a fan of having to use
Java though!

Lots of bookmarks. One of my faves is:
https://wiki.archlinux.org/index.php/Btrfs


It will be interesting on what happens. I rsync'd the clients data
from a 2TB mdadm RAID to a standard 3TB BtrFS drive, Currently running
 Duperemove on it. I reckon it will take days but it will be
interesting to see what happens.
