there are also corner cases depending on filesystem used on top of the logical volumes, there is often no fail-safe behavior when you fuck up sizing or lose backing devices, you need to handle application level sync yourself (like locking DB tables and letting buffers flush to disk), etc. did you expect training wheels?
They also don't solve the problem of restoring a fragment of data (e.g, a single accidentally deleted file) from a backup in an untrustworthy environment.
are you a volume shadow copy user? ;) the poor man's way to handle this is mounting the RO snapshot somewhere, and invoking and rsync, afick, $your_favorite_tool to see what changed and copy/restore what you want. _______________________________________________ Full-Disclosure - We believe in it.
