Which Databases Should NOT be mirrored in SP2013?

Question

I'm in the process of creating a mirror for our newly built SharePoint 2013 farm. I know that the content databases can be mirrored, but what of the other ones? I know that there were special databases on SP 2010 that you weren't supposed mirror, but I've not been able to find much on Google searches.

I have the following:

• SharePoint_AdminContent databases
• 4 x Search_Service_Application databases
• SharePoint_Farm_Config
• UsageApplication

Answer 1

You are right in SharePoint 2010 there are two databases that do not support mirroring :

• User Profile Service: Synchronization database
• Web Analytics Service: Staging database
