I just ran a test dump of a Netapp F760 Filer.  The volume is 200GB total
broken down into "dataglobs".  Each dataglob has its own disklist entry
about (50 or so).
The backup runs over nfs via tar.  Amanda has a 200GB IDE spool disk.
The drive is a Sony AIX-700C (40GB/hr) inside a automatic tape changer.

This backup took 50 hours to complete.  Anyone know of any obvious things
I can do to speed this process up?

Thank, TAvis

# For completeness Amanda should calculate the inter-record gaps too, but
it
# doesn't.  For EXABYTE and DAT tapes this is ok.  Anyone using 9 tracks
for
