HP 1/8 G2 Autoloader 920 very slow backups using Backup Exec 12.5

[Adam_Morris]

I am getting about 4MB/minute which is VERY slow... I have tried everything I can think of to get it up to speed but nothing has worked.

Things I have tried:
1. Updating all drivers which include NIC, Tape Drive, Library and SCSI card.
2. Using Symantec driver to tape drive
3. rolling back each driver one by one and mixing and matching.
4. uninstalling all the drivers and re-installing them.
5. used Library and Tape Tools and still slow there which tells me nothing is wrong with the network connection since I tried it backing up locally...

Wondering what the "perfect" combination of drivers would be for everything...

I have a new HBA Adaptec 29320 coming tomorrow. It had run at higher speeds before so this tells me some update or driver was changed...

I am using the Symantec driver for the tape drive and still very very slow.

We have a PCI-X card coming to us, should be here tomorrow. I hope that is the cause but it was working for a short time before something got updated...

It wasn't working to it's complete potiental but it was way faster that 4MB/minute.

[Adam_Morris]

So we got the new HBA in.

Adaptec 29320A..... It's still slow.

1. Updated HBA driver to latest from Adaptec site.
2. Updated Tape drivers with latest Symantec Driver - still slow
3. Used HP Tape driver - Still slow
4. Used symantec to backup to disk and it was operating at 2GB/Min.... this is more like it... Still wont backup over 100MB/min to tape though...

Anyone else have any suggestions?
