Hello @Nikhil Reddy Kasam ,

Thank you for reaching out to the Microsoft Q&A platform. Happy to answer your question.

Synchronization of data between 2 existing VMs is not possible. We don't have a feature like that. If you are looking for disaster recovery options for your VM, you can use Azure Site Recovery (ASR) A2A replication that ensures to sync the disks of the Azure VM(s) to another region.

Only when in need of recovering the VM on the DR region, you can initiate a failover and ASR will create the VM in the secondary region with the replicated disk. This way you can save on compute resource costs. During the replication phase only data storage and ingress n/w bandwidth will be charged.
