I don't see why it would be incompatible, compressed blocks are data like any other. COW and subvolume snapshots work with compressed nodes just as well as with regular ones... > - data across subvolumes Wasn't the "cp --reflink" across subvolumes merged to mainline quite a bit ago? Under 3.6.9 it works fine for me... Also, the blocks are shared between subvolumes if the other subvolume is a snapshot of the first one. Besides, I think that doing a rsync from remote server and snapshotting the subvolume dedicated for server will be the standard approach.
