Also, after you do yr backups:
automate them, so you don't have to remember to kick off the backup manually. Or else you'll remember, like, once every eight months. I speak from experience, here. If you can't automate the backups, at least set a regular reminder and write down your *whole procedure.*
And.
Test your backups. Make sure you can *actually restore* from your actual periodic backups.
Admins, back your stuff up right; the federation is counting on you!
