[plug] tar and multi-volume archives

[Michael]

With my recent experience here, I would suggest using the -L option and 
formatting/mounting those drives. Its not that the M option didn't work, I 
didn't try it, I don't like theory. The only drawback to the -L options is 
that you'd need to label the drives :)


Kind Regards
