I have a client running SBS 2003 SP2 with Exchange SP3. They have a two 140GB drives (divided into into two partitions) configured as RAID 1. There is 18% free space on the C partition and 40% on D.
We have NTBackup configured to run on a nightly basis to external USB drives. The backup used to take 7 hours then starting on 10/23 the backups now take about 20 hours to complete. I have tried changing USB ports and setting up a new USB drive but the problem persists. The server has USB 2.0 ports.
Does anyone have an idea as to why the backups would be taking so long now? There was no increase in the amount of data stored on the server. The only change on the network was that we replaced four old XP workstations with new Windows 7 machines but that should not affect anything on the server. We are running AVG on the server but no scans are scheduled and I've disabled the Resident Shield and Virus Scanner to see if that improves things.
Any thoughts or suggestions would be appreciated. Thanks.
