It all depends.  Does your largest disklist entry fit on your holding
disk?  Look further down in your daily report and look at the times
for dumper and taper for each disklist entry.  My guess is that you
are doing one or more direct to tape dumps across the network, which
can be extremely slow since the tape may have to repeatedly stop and
reposition itself as the data trickles in.

It is saying it took 11 hrs to dump 54GB or 24GB compressed.  I have a
quantum DLT8000-40 which is rated
at 6MB/s or 12MB/s compressed.  11hrs seems a long time even considering
gzip as the software compression.
Is there something I am missing here?
