Backup job hangs for multiple virtual machines

If the policy specifies multiple virtual machines, and the storage unit "Maximum concurrent jobs" option is set to 2 or more, the backup may hang. If you have Symantec Endpoint Protection on your Hyper-V server, make sure that it is at version 11.0 Maintenance Release 4 (build 11.0.4000) or later. Backups of multiple virtual machines with multiple concurrent jobs may experience this backup problem with earlier versions of Symantec Endpoint Protection.
