Not a word about the hardware but I found better performance on dual core or before that dual CPU setups. Nothing in your post reveals where a hardware bottleneck could be since you wrote nothing besides it was slower than you would like.
How serious are you to speed this up? Will you get a DLT backup on fast SCSI, add RAM or go to a dual core server?
And the big question. Did you make the cheap call to Microsoft?
I am running a single exchange 2003 server on the network and am using windows backup to backup the information store and system state data to an external hard disk. The backups run fine however are taking an outragous amount of time. (About 8 hours for 30GB, further 8 hours for verification). I have scheduled maintenance tasks so that they run at different times to the backup with little effect. I have also trolled through the logs at the times the backups are running and they are error less. Any suggestions would be greatly appreciated.
Thanks in advance,
