Gosh! That's certainly creative. And a good reminder to keep up-to-date backups.
If your backups are too up-to-date, you could back up the virus and screw up your backup too! Make sure you every once in a while that you make a separate full backup and don't keep overwriting the same backup.
I have two external backup drives. I do backups with Time Machine (iMac) on one of them for a while, then the other one for a while. And of course, Time Machine lets you choose the date you want to go back to.
I was looking for something in one of my storage closets the other day and noticed that I still have a floppy with Fastback and my last backup from my old 80286 PC. It took a whole box of floppies to make a backup, and it would tell you when to remove a disk and put in the next one. There were no photographs or media. Just programs and my files. Now I have 2 1T HDs that are each less than 1/10 the size of the 500MB HD I used for my previous computer.
