You’ve got DPM installed, and for the most part, configured. It’s working, but you have transaction log drives filling up on some of your servers, and it’s not really clear why.
Wanna know why?
Here’s the answer:
It’s because the UI is very unclear, because the documentation is unclear, (there was a hint of it on page 83) and because the things that would be obvious to a DBA simply aren’t mentioned.
Tom has a very detailed post on the topic, making it a must-read if you use this tool.
