tar for "full" floppy backup?

As it stands, it's possible to backup to multiple floppy disks with tar, but these cannot be compressed during the archival process.
Why not use tar twice: first with -zcf to make a compressed archive and then with --multi-volume to write the archive to floppy. Of course to retrieve it, you will also have to use tar twice: first with --multi-volume to reconstruct the archive and then with -cvf to unpack it.
What result would you get with that method if you wanted to review the multiple archive's details with -->
tar --multi-volume -tv --file=/dev/fd0 > backup.log
-->? Not that much detail. Just that one big file.
The tar backup routine I've described with your BasicLinux distribution barely took over six floppy disks, yet I still want to check out the results, or at least have them available. (And I've done just that -- I can review the results of that backup from a file that had the results directed to it while using the tar command above.)
For quick backup of important files, though, I'm using the following script -- perhaps a little "busier" than it needs to be, but then I'm just a "linux-newbie"... ;-)
-----------------------
cd /home
mount /dev/fd0 /fd14
tar cvpf hot_backup.tar /etc /home /root /var/eznet gzip hot_backup.tar
rm /fd14/hot_backup/hot_backup.tar.gz
mv hot_backup.tar.gz /fd14/hot_backup umount /fd14
echo "***FINISHED***"
-----------------------
This works nicely to backup all of my important files, which I can do much more frequently and easily than the full backup routine with tar. What's more, I can also view the results of this file under mc.
This "hot_backup" routine created a tar/gzip file only about 132k in size. My rule of thumb is that, when my important file backup exceeds the size of a 1.44MB floppy disk, it's time to fully backup my system.

Wrong, the extract command in the second part would have to be tar xvf not tar cvf.
