The backup rate is affected by the time to calculate checksums on the server and the client and if you have compression turned on for your pool files then it includes the time to compress / decompress files to/from the pool (hash collisions require complete file comparison). What is your processor doing during this activity. Remember that each backup session is single threaded so your speed will be gated by the speed of a single processor. -- Jonathan Craig ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
