I use Git, mainly because I don't like the central-server-dependency of SVN.
However, I'm not always stringent about committing often.
If I need something backed up, but don't want to create a new repository, I'll just zip it up where it is, so I can revert if I need to.

Last year I didn't teach my programmers to use revision control, because I didn't think they were there yet; they were still getting familiar with the language and with programming, and didn't understand why you would want to have regular backups.
This year I think I will. TortoiseGit should make it a lot easier. (A terminal is not an intuitive interface, even for me.)
