CMirror is a very simple versioned backup utility that manages to be extremely useful by picking the right things to (and not to) do. It is designed such that all you do, pretty much ever, is type "cmirror" when you're done working. It then figures out what needs to be done and does it with minimal intervention.

Some nice features: repository stored in simple files-on-disk form, so you can easily browse and access old files without running cmirror; automatic execution of external programs prior to checking in new files; maintain versioned backup even when away from the server, then add all versions back to the server when reconnected; easy-to-use but powerful wildcard support for controlling which files are included for various operations; and many more goodies.

Versions: CMirror 1.3c
