Slow Backup times - 60MB per minute job rate

I recently had to change my backup tape drive as my old one failed. However im currently only getting 60MB per minute instead of the 400MB per minute i used to achieve.

The drive is a LTO 2 on a raid card along with other devices, i know that its not recommended but my pervious drive was as well and it worked fine.

I have used the latest veritas drives for the drive itself and it knows what it is and is working just at a slow rate. Its taking in excess of 42 hours to back up 125GB.

The drive is only backing up the server that it is connected to.

Any help would be appricaited.

Have you tired running C:\Program Files\Symantec\Backup Exec\tapeinst.exe with the option of removing the unused drivers and updating the new ones?

Good morning, sorry for the delay in responding, i had to wait for the backup to finish before i tried anything.

I ran the tapeinst.exe which Azyre mentioned but this didnt seem to solve any problems unless there is something you have to do after running the exe and restarting the server?

I cannot really remove all the other devices as they are all HDDs which are running the RAID to store studnet data (work at a school).

How do i check the firmware level of the tape LTO? Thanks Rick

I faced the same issue, i received 5mb/min. I tested local files which also showed same speed then i guessed it may not be a network issue. I checked the SCSI controller driver, it was a bit older. I updated it, and found the result very soon! after this i got 400mb ~ 1gb /minute!

So, check the scsi driver is the hit point, as TEMPTER pointed.

Thanks to all
