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
