We run a nightly archive of 70 GB that is taking just over 8 hours
uncompressed.   In our Magstar 3570 we have two different tape drives.   My
question follows:   Is it possible to be running two different archives at
the same time to cut down the processing time?   If it is possible how
would
you go at it?


If you are able to allocate 50-70 GB of disk space I would recommend you to
create primary storage pool of type DISK and setup that its next storage
pool is the tape pool defined on 3570. Later set its migration thresholds
average low (for example HighMig=30 LowMig=0).
This must speed up your backup and probably you will finish faster than in
8 hours and migration processes will start for both drives moving data from
disk storage pool to tape.
