I have now attached a ADIC Fastor 7 Slot DLT 7000 (DLTtape IV) drive
And the backup times have went from approximately 2 hours to 23 hours.

Not only the tape seems slow, but almost everything!
The estimate time went from 10 minutes to 25 minutes
(that could still be normal).
The dump time went from 2 1/2 hours to almost 22 hours!
Do you have networking problems (e.g. a duplex mismatch
is a frequent problem). Try "netstat -i", and notice
if you have a a large error count.
There was also one filesystem added? Maybe that the cause?
Or did you bypass the holdingdisk for one or more dumps?
What could be the problem? I think I have the right tapetype
configuration in the Amanda.conf file.
I believe the tapetype is correct, but you generate one yourself.
It takes about 6 hours. Insert a scratch tape and type:
amtapetype -e 35g -f /dev/your/tape
I also don’t have a changer.conf file?
If you don't have a changer, than you don't need one :-)
