Currently I use Networker Module for Exchange 5.1 on my Exchange 2003 system.
However, we are putting in an Exchange 2010 system later this year and I wanted to know what people thought about moving to NMM for backups.
Is there benefit to doing this? If so, what will I gain?
Is there risk?
If you browse through the discussions here on this list, and also on other lists online (e.g. listserv.temple.edu) you're going to find that there is not much happyness with NMM so far.
But NMM 2.2 sp1 is recently out. It's supposed to include a client check programs that make configuration easier. I going to give it a try very soon and hope it's going to be configuration friendly and stable.
