We always found that DLT 8000 tapes worked well in parallel. When the backup got so big that it wouldn't fit on two DLT 8000 tapes, we split the backup putting the databases on two tapes in parallel and everything else on a third tape. Keep in mind, we didn't have a backup strategy. We had a recovery strategy and backups were a part of that. We found, for us, organizing backups in this manner allowed us to speed recovery, which was far more important than anything else.
You can achieve good times doing Store-to-Disk backups. But then what? Do you backup the STD to tape and send it offsite? FTP is somewhere? The recovery times on getting this back are too slow.
I would be happy to discuss your recovery strategy, high availability and any other HP3000 system administration questions. You can look up my website for my phone number.

Subject: [HP3000-L] Validate data on tape drive
Once again I'm dealing with some MPE stuff and need assistance. You would think after storing files on tapes after 10+ years we would have found a better way to do this...
We use turbostore with 4 tape drives and need to find a way to validate the backup. Vstore appears to only have ability to use 1 tape drive. Currently I have some empty files scattered through the system and use a separate job to delete them, remount the tapes and restore, trying to access all 4 drives.
What method or software are you using? I'm sure many of you are using SAN or disc and of course tape backup is rather antiquated in today's environment.
TIA!
