Get a good UPS!  If only the electronics in the drives are fried, you 
can still recover the data by using the circuit boards from identical 
drives.

What about a higher capacity tape drive?  How would that compare to a 
DVD writer?

OK, then using the CD writer for daily backups seems reasonable.

I wouldn't install/remove the backup drive once a week, but you could do 
it using a drive bay.

Man, if you have so much data that is valuable, why not go SCSI RAID 5?
