Seven days ago, we upgraded from Backup Exec version 10 (5520) to Backup Exec version 10d (10.1 5629). I upgraded all my Remote Agents to 10.1, I upgraded my tape drives to driver 5.1.1.1 (driver date 1/31/2006).
Since the upgrade, my throughput rates have dropped significantly. For example, I went from backing up our SQL servers at 2.8 Gb/min down to 1.6 Gb/min. Exchange went from 2.5 Gb/min down to 1.8 Gb/min. This is a big difference in the amount of time it takes to do a backup.
I not only have the speed degregation issue, I also have a problem with the backups using five extra LTO2 tapes for this past weekend's full backups. There was no significant data increase to cause Backup Exec to use even one more tape but all of a sudden, it requires five extra tapes for our full jobs. I have the same compression selection as before so I am guessing that ver 10d (or the tape drive drivers) doesn't handle the compression as well and that is why it is using the extra tapes...
So with Backup Exec 10d, our backups are running much slower and it uses many more tapes for the same amount of data. I have read past posts and have talked to a couple other contacts who have the same exact issue I have. I really do not want to roll back to version 10, that will be a last resort but I will do that if nothing else fixes the problem.
I would love to get some feedback on this, maybe someone had my same issue and knows of a simple resolution...I hope. :)
Thanks in advance to all...
