At our shop we have used quadstor - http://www.quadstor.com with good amount of success. But our use is specifically for vmware environments over a SAN. However it is possible (i have tried this a couple of times) to use the quadstor virtual disks as a local block device, format it with ext4 or btrfs etc. and get the benefits of deduplication, compression etc. Yes btrfs deduplication is possible :-), i have tried it. You might need to check on the memory requirements for NAS/local filesystems. We use 8 GB in our SAN box and so far things are fine.

Hi list,
is there any working solution for deduplication of data for centos? We are trying to find a solution for our backup server which runs a bash script invoking xdelta(3). But having this functionality in fs is much more friendly...
We have looked into lessfs, sdfs and ddar. Are these filesystems ready to use (on centos)? ddar is sthg different, I know.
Thx Rainer
