All,

We have Exchange 2010 servers in a DAG that also have public folder databases.  
We have 6 mailbox servers, two of which house public folder databases.  We are 
using TDP for Exchange v 6.4.  Within about 10 minutes of starting a public 
folder database backup, we see cluster service errors (Event ID 7024 " The 
Cluster Service service terminated with service-specific error A quorum of 
cluster nodes was not present to form a cluster.") along with DAG database 
failovers.  Has anyone experienced this or see a problem with our procedure for 
backing up public folders?  Thanks for any advice!  Please let me know if you 
require more information.

Peter
