Much like EHaskins wrote, but different: Get 2 drives, copy everything onto both. Team gets one, you keep the other, on a shelf. When other drive crashes, copy your drive onto yet another. Repeat as necessary.

This can also be done year after year - fill each drive, copy it, then put one on a shelf. Repeat forever.

Just be sure to pick a technology that will be supported in the future (such as USB or SATA), or maintain a machine just for that purpose (Consider 8-inch floppy disks; good luck finding a drive if you don't have one already)
