Very coincidental conversation
I have been looking into dedupe for a while.
I am currently testing BtrFS on duperemove. Bedup is more file level
and I didn't get a lot of saving with all the virtual images I am
I am testing on:
root at Ubuntu-14:~# 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 at Ubuntu-14:~# btrfs --version
My client data is 1.7 TB mainly of virtualbox images, shadow protect
and standard Microsoft backup images.
Posting to the BtrFS mailing list they say that I should be using a
3.15 RC kernel to get the latest patches.
What I am trying to achieve is an offsite backup capability for VM
images. Hopefully to be able to backup offsite on a block level. ZFS
(ZoL), BtrFS and SDFS all do this.
In the past I tested Opendedupe. http://opendedup.org/ they have a new
version now so I may try them again. The Java part of SDFS is annoying
ZFS Dedupe is a constant and reading about it, they say it requires
20GB RAM for 1TB of data.
Opendedup is different again. BtrFS seems the go but not stable enough
yet for the features I want.
