Normally GNUTAR should support Multivolume backups but I just tried it on my
Interactive.
I prefer cpio to make Backups and it seems to be reasonable fast.

find /usr/local -print | cpio -ocdvB > /dev/rfva0.

It is also possible to change diskettes (720K to 1.44MB or whatever) when
you use cpio. But you have to type a lot more.

dump is one of the utilities developed in "Coherent stone age" and I never
used it or will use it.
Also: Ever tried ustar, the TAR-Link to pax ?
