Is the source 7.3 and the target 6.5?

Obviously, there is an issue with the version. The resource group feature is only available in version 7. Don’t use the version 7 br with version 6.5.

Uh, yes, I am deploying BR offline. The current BR version is too high; backup works, but restore does not.

It’s a version issue.
