HPSurestore 818 DLT autoloader - DLT40/80 Tapes - Backup Exec V7.3. Backing up MS Exchange V5.5.
The backup runs at 400mb the verify runs at 300mb. No problem with this for weeks then suddenly the verify rate will drop to -100mb. If the tape is then put in another internal Compaq 8000 tape drive and a new verify job created then this runs at over 300mb. The only way I can get around this so that I can run the backup and the verify in the autoloader drive is to swap the tape out with a new one and then it is fine for a few weeks before it starts happening again. Anyone know what would cause this.
