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.
