Back-up all of your physical media.  Immediately begin fretting about having back-ups to the back-ups.  Consider buying additional back-ups.  Begin fretting about cost.  Then allot time for fretting about all of the lost time of backing up physical media, only to lose it because you didn’t back-up your back-ups.

Then pity yourself and wonder how much your time is worth if you’re not being paid for it.

Oh, and don’t forget to insert the next disc.  (Finally: repeat.)
