Starting with the 6.2 release, we added a feature to help with this problem, at least for CIFS clients. If you turn on the cifs.snapshot_file_folding.enable option, the filer will compare newly written files with the same file in the last snapshot, and any identical blocks will not result in new allocation of space. The effect of this is to only allocate storage for blocks that have changed. This is also useful when you are doing SnapMirror, since only the changed blocks have to be transmitted.
Is there any chance of adding this feature for NFS clients? It might help us with an issue we have on one of our filers.
