This is the major problem with using just tar.  It will not to
multi-volume compressed archives.  The only way you can to this is the
tar your whole disk (or parts of it) into one big tar file, and then
dump it to floppy with tar's multi volme operation.

I have recently copmleted a major over haul of my diskback-0.1 program.
It seems to work alot better.  And will be releasing it just as soon as
I finish up testing it.
