Backup Exec 11D - Disk to Disk Slower than Disk to Tape

Hi

can you attach one additional hard disk locally with out raid and check the backup throughput to the disk.

What is the controller to which the disks are connected. Can you check it has the latest drivers.

The possible issue might the contoroller or issues with the harddisk.

So adding additional disk and running backups to it would give you the right direction.

Normally backup to disk runs faster than to a tape drive.

I narrowed it down to being the hard drives. I created a copy job from Backup Exec 11d and only changed the destination to disk instead of tape. What gets me is that my tape backup to tape takes 1 hour for a particular job and 8 hours to disk for the same backup job.

I will check the controller drivers as you suggested. Will keep you posted.

Updated the firmware on the controller and updated the driver to the latest and still no improvements.

Is my disks not capable of handling more?

Since I didn't have another internal disk to test, I used Maxtor USB drive. At first it began with the same backup speeds, but when it finished I was surprised to see that it reached close to tape backup speeds.

Tape 900+ MB/Min
USB Disk 660 MB/Min

I'm going to update the BIOS. Read something bout that.

Here it he list of SCSI controllers I have.
