Tyan Thunder K8WE Server board
Dual AMD 280 Opterons
4GB RAM
Two nics each use Nvidia NForce Pro 2050 and 2200 chipsets.
This workstation had XP Pro x64 and Symantec Backup Exec
Adaptec 29320 SCSI controller
HP LTO 3 tape drive
Two Exabyte VXA-2 tape drives
My previous backups took 2.5 hours to complete in Backup Exec. Bacula ran for 5+ hours.
