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. - jb Rainer Traut <tr.ml@...> writes: > > 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).
