BTRFS deduplication
Hi again list,
I've seen in a message dating back to january that offline deduplication has been implemented in BTRFS, but I can't find it in my btrfs-tools 0.19+20100601-3ubuntu2
Has it reached release, or not yet ? How could I give it a try ?
I've seen a discussion about whether deduplication should be made offline or online ; my usage case it to backup a number of laptops having all about the same software and many files in common, to a single backup server using rsync, I would be very much interested in online deduplication - because I don't have "n" times the storage space, that offline dedup might temporarily need, and because performance isn't crucial for this application, as backups can be done overnight...
Thanks in advance :-)

So the btrfs-progs patch only exists on the mailing list and the kernel=
patch is
sitting in my git tree. This was more of a weekend project and less of=
a
serious attempt at an actual solution. It could be cleaned up and actu= ally
used, but I'm not at all interested in doing that :). Thanks,
Josef
