I have a IBM P660 6MI server running AIX 5.1 ML6 and Amanda 2.4.2p2.
I originally had my backups running to the internal 8MM tape
drive.
define tapetype ibm-20gig-8mm {
length 17636 mbytes
filemark 178
kbytes # don't know a better
value
speed 2116
kbytes # dito
}

I have now attached a ADIC Fastor 7 Slot DLT 7000 (DLTtape
IV) drive
define tapetype DLT7000-IV {
comment "DLT7000 with DLT Tape IV
uncompressed"
length 35000 mbytes
filemark 8
kbytes # don't know
a better value
speed 5000
kbytes # dito
}
And the backup times have went from approximately 2 hours to
23 hours.

What could be the problem? I think I have the
right tapetype configuration in the Amanda.conf file.
I also don’t have a changer.conf file?
Any help is greatly appreciated.
