Did you back up to floppies in 1995?
1995 shipping hard disk size: 512 MiB
1995 shipping floppy size: 1.4 MiB
Floppies required for a full system backup: 366
Current shipping hard disk size: 200 GiB
Current shipping CDROM capacity: 700 MiB
CDROMs required for a full system backup: 293
You could cover your needs with 1-2 large capacity tapes.
Incremental backups would be even smaller.
Note that CDR as arechival media for old projects is reasonably sane.
For system backups, it's idiotic.
Peace.
