We had a similar discussion a couple of years ago here, under the title
"A Versioning FS". Look through the archives for the full discussion.
The jist is that application-level versioning (and consistency) is
completely orthogonal to filesystem-level snapshots and consistency.
IMHO, they should never be mixed together - there are way too many
corner cases and application-specific memes for a filesystem to ever
fully handle file-level versioning and *application*-level data
consistency. Don't mistake one for the other, and, don't try to *use*
one for the other. They're completely different creatures.
