This could be a simple question. But wondering I could get an good answer on this.. In Exchange 2007, we use to perform the backup on passive copies on a CCR node. ( Even if there would be a SCR, the passive node of CCR taken to perform the VSS backup). In Exchange 2010, we have multiple passive copies. Which passive copy taken for the backup and is there any priority for that.

Simply, it depends on the backup product you're using and how you configure it.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Hi, There would be no difference between these copies when you do the backup. If you have activation preference specified, then I recommend you to have a look at the article below: Understanding Active Manager http://technet.microsoft.com/en-us/library/dd776123.aspxXiu Zhang TechNet Community Support
