With a SAN agent we have achieved 24.2 MB/sec on TDP for Exchange for an information store of about 15.2GB.
My guess is your anti-virus software or network connection are a problem. Paul D.

At the moment I'm only getting approx 500Kb/sec at a time when no other backups are running, i.e network and server and doing very little. I've tried various settings for TDP buffers/buffersize to no avail. Environment details below. If anyone has any thoughts on how I can make this perform better I'd appreciate it.
