>Thanks to those who answered my queries/problems with turbostore.
>I can see that my assumption that turbostore filled a tape before ejecting
>it in parallel mode was incorrect.  The fact that turbostore has to first
>count the files to be backed up and then determine what file go wheres would
>also contribute to the extra time it takes to complete a parallel backup.
>However I do attribute most of the problem to the C1511A (first generation)
>DDS drives we have.
>The DDS drives are on 2 seperate HP-IB.
>The 8 disks are on three SCSI.
>There is absolutely nothing else (including the network) running on the
>system when a backup is in progress (even incremental).
>We use the interleave;progress=3;compress=high options, and for the
>fullbackup we also use the maxtapebuf.
>It is much easier to use a sequential mode backup for the incremental backup
>because it can complete without operator intervention while the system is
>unattended.  This saves wasting time for another tape to be mounted when the
>operators come on duty.
