Well, there's one of the differences between backup and file copy. If you
introduce a spare disk to a system then, at least in the case of the various
post-'9x Windows, the OS "sees" it, registers it, and any viruses on the
system
are, immediately on that drive as well. With a TAPE utility, however, virus or
not, if the program runs, it copies the data to tape under control of a backup
utility that either doesn't work because it has been corrupted, or, if you were
clever and run the program form a write-locked removable, then it (the backup
utility) runs on the removable platter and transfer the data, corrupted or not,
from the hard disk to the tape. Viruses can't deal
directly with the tape, just
as the OS can't deal directly with the tape. A
virus that gets onto a tape
won't be an executable, hence probably won't go there except in the form of
already-corrupted files. As a result, I've concluded DISK is unsuitable for
backup on Windows PC's. Now, I recently saw a DVD writer for under $500.
($375) If there's any sort of support software for backup, that might present a
useable solution, since a DVD writer would not appear to Windows as a disk
drive.
Of course, MAC OS may not be so virus friendly, but I don't know about that.
The "spare" HD would have to be a SCSI drive, right? How does the MAC go about
recognizing a valid SCSI device? What has to be done to a JAZ platter to make
it (the MAC) recognize it.

These days on today's PCs, it's easier to buy a spare
hard disk, and copy (using 'at', the scheduler, TaskZip,
whatever) your vital files to it. Take a tape backup
off-site as frequently as you like, or just carry the
spare hard disk.
