Unable to backup Server 2012 R2 on failover cluster.

Hi,

We cant backup Server 2012 R2 in failover cluster but standalone server 2012 R2 can be backup without any problem.

We are using Netbackup 7.7 to backup data.

Our envrionment is configured at below

• Netbackup Master/Media Server: 2008 R2, Netbackup 7.7.1
• Failover Cluster: Windows 2008 R2
• All our servers are 2008 R2

We create new test cluster with Server 2012 R2 to see if we can backup but we cant in server 2012 R2 is in cluster but if its standalone server it all works fine.

Thank you
