Cause
The message, its cause, and workarounds are discussed in the following VMware knowledge base article:
Unable to use Snapshots or perform a backup on virtual machines configured with bus-sharing
http://kb.vmware.com/kb/1006392
VMware does not support snapshots of virtual machines configured for bus-sharing. This means the virtual machine cannot be protecting using the vStorage API.
Solution
These virtual machines are configured in such a way that they cannot have snapshots created. If you cannot disable bus-sharing for the client, you may need to back these up with a NetBackup client installed in the guest operating system rather than using the VMware Agent.
Applies To
NetBackup 7.x with VMware agent.
