Perhaps I'm misunderstanding something here, but why can't you do that
with ordinary forward deltas, as long as all the necessary information
is stored with the backups? Are you saying that classic forward-delta
based systems don't store backup metadata (or whatever the right term
is) on the backup server, but on the host? What happens, then, if the
host's storage is unrecoverable?
