Description Raghavendra Talur 2022-09-21 17:55:56 UTC 
Description of problem (please be detailed as possible and provide log
snippests):
It is possible that a user creates two DRPCs where both try to protect the same PVC on the managed cluster. This should be prevented as the result is non-deterministic.

There are multiple ways to prevent it from happening. One of which is VRG should ensure a PVC is protected by one instance of VRG and not more than one.


Version of all relevant components (if applicable):
4.11 and lower

Proposed solution: When a VRG protects a PVC it adds an annotation from ramen. We should look at adding a second annotation that links back to the VRG which protected it.
