I use snapshots intensively. I currently have 6 monthly, 5 weekly and 7 daily snapshots active with a rotating algorithm. Does the new implementation copy dirty blocks also in "all" active snapshots or is it now possible to use the cow-blocks "cross-snapshot"? I mean that a new dirty block is only copied into the oldest snapshot and all the other ones can use that one. NetApp's Filer does it this way.
