Hi Paul, I'm backing up a lot of 2008 R2 Servers without speed issues. I've seen cases where a faulty nic driver caused such problems. Have you monitored the network interface and watched what happens (with wireshark for example)? I did not follow this thread - so this might have been suggested: Compression on the fileset may cause slow transfer rates Kind regards Julian ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
