Hi Richard,
I am not talking about source(ASCII) files. How about versioning
production data? I talked about file level snapshots because
snapshotting entire filesystem does not make sense when application is
changing just few files at a time.
CVS supports binary files. The nice thing about version control systems
is that you can annotate the versions. With ZFS snapshots, you don't get
annotations.

Most folks use SCCS, CVS, or some other version control system for this
sort of task. These will work fine on ZFS.
