How problematic state appear:
Attempt to create Private Endpoint for Recovery Service Vault has not finished with success (failed state)
It looks private DNS zone creation was not performed correctly (privatelink.plc.backup.windowsazure.com and privatelink.queue.core.windows.net)
I was able to create those zones manually.
Have tried to create another private endpoint on this Recovery Service Vault, but same failed state result.
Possible workaround:
I was able to create another Recovery Service Vault with private endpoint with success, but i need to be able to keep my backup items collected by old Recovery Service Vault and don't want to keep two Recovery Service Vaults.
