Sharepoint 2010 backup fails with error unable to query the team database metadata

Problem

The backup of Sharepoint 2010 User Profile Proxy fails with error 'unable to query the team database metadata' when User Profile synchronization is enabled.

Error Message

Viewing the SPSWrapper debug log of the failed backup will show the following error:

Solution

 

This is similar to another issue described in TECH166208 except the error is in a different object. The SPSWrapper debug must be reviewed to determine which issue is present, in this case the exception is in getting the IsSynchronizationRunning property.
