Can Azure VM disaster recovery do zone-to-zone, region-to-region DR at the same time

Question

We have a case requires stand along VM due to the stuff running on VM does not support active-active load balance. Azure VM support zone to zone, region to region disaster recovery, but if just set zone-to-zone DR, it cannot handle region failure. If just set region-to-region DR, and if just VM crushed but region is not down, it will be overly kill to restore VM to another region in this case (would like to just restore crushed VM in the same region like to another zone in this case).

Is there a DR solution able to support both situation? It seems cannot setup both zone-to-zone and region-region DR at the same time on the same stand along VM. Can you please confirm if that is the case?

Hello @James Dong ,

Thank you for reaching out to the Microsoft Q&A platform. Happy to answer your question.
I can confirm that Azure Site Recovery DR does not support both zone-to-zone and region-to-region DR at the same time on the azure VMs at this time as both uses same ASR replication/failover approach in the backend. Hence you need to select one of the technically feasible DR approaches for you either region-to-region or zone-to-zone.
In addition to the Disaster recovery either zonal or regional, you can plan to have azure VM backup configured. In case of issue with the files/folders or even the disk or entire VM, you have a way to restore the VM at a granularity.

This backup will serve as an additional protection and secondary recovery option for you.
