Mary: We have greatly simplified our backup/archiving strategy by switching from storing our master images from the TIFF format to JPEG2000. The latter are much smalled and are thus easier to archive to optical media. Once a digitization project is complete we delete the TIFF images. We now are able to store copies of them in more places than before because they are so much smaller. We can keep lots of copies without stressing the the storage devices and tape backups.
I was very nervous when I deleted my fist batch of TIFFs, but I've gotten over it. I hope I don't live to regret this irreversible action.
