The above setup, while it will work, is considered to be dangerous
to your data because you will at any one time, be over-writing your
only copy of last weeks work with the current work. If you were to
have a power outage in the middle of writing a tape, the whole
thing is blown. Its considered to be good practice to have at
least 2x or more runspercycle tapes in tapecycle. These tapes are
quite inexpensive so get another 10 pack so you'll have spares,
putting say 7 or 8 of them into the tapecycle. By doing this, you
are assured of haveing a full backup of the system at least 2
dumpcycles deep.

^^^^^^^^^^^^^^^^
This can be run up a ways if you have plenty of ram, I use 60 here
with half a gig of ram.
>runtapes 1 # number of tapes to be used in a single run of amdump
Your tapetype is only a 2gigger, is this big enough?
>tpchanger "chg-manual" # the tape-changer glue script
^^^^^^^^^^^^^^^^^^^^
if runtapes is 1 then comment the above line out, else if it needs
more than one tape in runtapes, use chg-manual but that will
require your presence at change time.
>tapedev "/dev/st0" # the no-rewind tape device to be used
But you have specified the rewinding device here, it should be
/dev/nst0. Using st0 is a big non-no.

you don't need any of this from here

Humm, thats not the stock HP-DDS definition, but one for a DDS3?
And was it made by the tapetype utility?
Was the drives compressor enabled?

You should probably uncomment the "index yes" line above as I don't
believe that a simple "index" below is sufficient to turn it on.
And you will need it.
