What happens to Geo-Redundant Recovery Services Vault in case of complete loss of primary region? RRS feed

  • Question

  • I'm using Azure Backup to backup some databases to a Recovery Vault that is Geo-Redundant. However, the documentation says 

    "You can restore the database to an instance of a SQL Server in the same Azure region."

    What is the sense of backing up to a geo-redundant Recovery Services Vault if we can't restore a backup to a different region in an emergency? Or am I missing something? I know I can do ASR, and that might be good solution if my churn allows it, or Always On AG async replica, etc. I'm just curious if and how you could ever use a Geo-Replicated Recovery Services Vault that contains backups. It seems like I have more control if I instead just did a SQL backup to geo-redundant blob storage, I have more control over access to that I think.

  • GRS is intended to be used only when data center is down and Azure declares a disaster. If the data center is down, you should able to access recovery services vault, just as would do on a normal day, but the data in the background is obtained from the paired region after storage does a physical failover. Hence this covers regional disaster scenario. In case, you are looking at the ability where the customer can restore to another region, you are referring to RA-GRS mode of storage. Recovery services vault doesn't support RA-GRS yet and we are planning for it.
