Hi I have managed to config the hard disk partitions in my disklist but
I am short of tape space to include the remainder of the hard disk

I had initially run the following commands is it possible to get
compression functioning to enable to use 40GB as opposed to native 20GB.
* - amtapetype -f /dev/nst0 # determine tape type takes along time
When specifying also a realistic estimate "-e 20 g" it is usually much
faster (2-4 hours)
* - turn off datacompression run mt command that controls magnetic tape
drive operation. * - mt -f /dev/nst0 status and mt -f /dev/nst0
datcompression 0 Compression off.
As I don't want to buy bigger tapes if possible.
If you already use software compression, than enabling hardware
compression will _reduce_ your effective tapecapacity by 15-35%, because
the compression algorithms in those tapedrives behave bad on already
compressed data.
When not too many files change, you can run less fulls and more
incrementals on each run by increasing the dumpcycle (runspercycle
actually). Or increase "runtapes" (and flush each morning the
remainders if you have only one drive).
