Stop what you are doing and take a backup right now! A co-worker of mine lost an important file today, which can happen to anyone at any time. He hadn't taken a backup for months so he couldn't simply restore the file. I don't want you to suffer the same fate, so I'm ordering (not asking) you to take a backup. Do it now, today, tonite, or tomorrow at the latest. If you had other plans, tell people that Doctor Q didn't give you a choice. You'll thank me later. If you think you have a valid excuse (no, a note from your mother is not good enough), let's hear it. Otherwise, get to work!
