There's a program called rsnapshot used for creating hourly backups, similar pattern may be applicable to deployments.
I'm currently using the :export option, which makes a duplicate of the entire tree (even if only 1 file has changed). The rsnapshot perl script I'm referring to uses rsync to provide the delta and only copies files that have been changed, added, or removed. It makes a hardlink of all existing files that have not been modified (saving on disk space) to create the rest of the un-modified tree. The advantage is that a deploy could take a few seconds vs. several minutes, and save on disk space.
