Firstly, os.listdir can't be guaranteed to return an alphanumerically sorted file list. You're making the assumption that the latest processed file will be the highest version number (when you use backups[-1]). I'd guess it uses the way the files are index on your file system, so if you want to make sure they are ordered a certain way, you should sort the return value.
You can do your filename check and extract the version number using a single regex: http://pastebin.com/ZF1XJs5S This use regex groups, which allow you to capture certain portions of a regex (in this case the digits representing the version number), and access them later. That way you can just store the version numbers and not have to parse the filenames for the versions again.
