Backup Exec v11d and Tanberg LTO tape drive - backup speed seems slow
Tandberg tape drive TS400
Driver provider: Symantec
Driver date: 1/12/2007
Driver version: 5.1
Tanberg
Block Size 64K
Buffer size: 1024K
Buffer count: 10
High water count: 0
Write single block mode: check
Write SCSI pass-through mode: check
Max 220MB/sec is all that get out of the backup
I am not sure if I should be adjusting the Block Size, Buffer size, Buffer count, or the High water count. Can someone please tell me if I should be getting better throughput than 220MB/sec

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
If this doesn't make a difference, check the backup log and try to figure out if it is slow only on a particular point of the backup i.e. Exchange.
