Set it and forget it, huh? Here's an idea I've just thought up (read the whole thing before actually doing this):
Buy Drive Image 5.0
Create a partition that's 1400MB (you'll see why).
Read about this program, then install it (
Karen Kenworthy's Replicator)
Set up a QuickImage schedule for the partition you've created. In advanced options, choose high compression so that half of 1400MB is 700MB (the size of high capacity CDRs). If you want to be safe and make sure that this doesn't go over 700MB, create a smaller partition.
Set up a schedule for Replicator to copy whatever files you need to the partition you've just created.
Now, make sure you have a blank 700MB CD inside your CD writer before the schedule runs. Tell me what you think...
