How Has This Been Tested?

• Deploy VM with compute / disk offering with encrypted set to true.
• Create a backup offering.
• Assign backup offering to the VM above.

When tried to create backup without a backup offering assigned, it fails with "VM has not backup offering configured, cannot create backup"

How did you try to break this feature and the system with this change?
