Git : have you ever tried to play with it ? For several years I’m working with that fantastic tool. Anyway the biggest problem is : if you don’t work day to day with Git, you need a memento or something similar (like my wiki 😉).
Also, if you use it for your personal usage, you’ll be lost when you will work with complex workflows. As I’m not a developer, I use Git to manage my etc configuration, my puppet manifests, my custom scripts…so many basic usage that really help me to win time as a sysadmin.
