we have some issues with our trilead backup to tape performance . Our environment: Trilead 6.1.005, Windows Server 2008R2 (Not virtualized). HP MSL G3 2024 Autoloader (LTO 6) (Directly attached to Backup Server by SAS). Backup Source: 20TB Infortrend SAS Backup Storage.
Trilead has a backup to tape performance of 43.9MB/s. HP Tape Tools measured a performance of 95mb/s. Both (The Tape Tools-test and trilead backup) was measured with compression on.
Our Backup Storage was measured (by Tape Tools) with a backup speed of 135mb/s.
Somwhow trilead only uses half of the performance available. I attached the performance screenshots.
Would be glad for any help. Thanks.
Edit: I may found the issue. The VMX process is using 100% of one core (Server has a quad core). Could this be the issue? If yes, is there any way to lower the cpu usage, or use multicore processors for trilead? If not, we need a hardware upgrade. (Backup Server is an old DL380 G5).
