@Pranitha Jupalli I am afraid to provide any insight Velero (since it's thirds party application) and more over we don't have any expertise on Velero.
However let me share some insight We may refer to this article for a replication scenario that can be implemented across regions
We have a concept of Paired regions as well where the same data is replicated across the 2 regions which you choose : https://video2.skills-academy.com/en-us/azure/best-practices-availability-paired-regions
Kindly let us know if you need further assistance on this issue.
