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.
