Thanks, I've been to hasty in posting questions without having read and
digested the excellent documentation at:

http://wiki.zmanda.com/index.php/File_driver

This is the paragraph that I misread:

The disk space you dedicate for your vtapes should NOT be backed up by
Amanda. Also, for performance reasons there should be NO holding disks on
the same partition as the vtapes, preferably not even on the same physical
drive.

But, upon re-reading it I see that it is clear as written.

My apologies!
