[Bacula-users] bacula lto-2 drive performance?

Hi all, I'm currently implementing a new bacula server running on a new dual core/dual cpu Dell PowerEdge 2900 server into a Dell Powervault 136T with a LTO-2 drive (IBM Ultrium-td2 model). The tape drive and robot are on a dedicated Adaptec 29160 card. The OS is OpenSuse 10.2 I think I shou

It was suggested that perhaps my 50 GB/hr data rate was due to the client maxing out around that rate. I believe I have verified this. Previously I had been used to seeing much higher rates on another backup system, but I was only backing up servers using high performance SCSI disks, RAIDed t
