I know people who are happy to image old disks into files if anyone has a copy of the actual disk. (If you're into soldering and have a 1541 disk drive, it's pretty straightforward to make an X1541 cable, but if not, other people have it covered.) The main thing is making sure there are multiple copies online of the resulting .d64 file so the data isn't lost forever. Getting it back onto a C64 isn't too tricky, as anyone with a C64 these days is more likely than not already familiar with the format and knows how to either copy it back onto a real floppy disk, or better yet emulate it on a cute little SD drive plugged directly into the C64.
