Question

SAN on-prem replication to Azure - How is it done ?

Ghady Frem 1

We are considering Microsoft Azure to setup a DR site for our on-prem environment.
We have a bunch of app VMs and some database VMs running in HA and are using SAN. What would be the service that is available on Azure that would replace the SAN and how can we always replicate the data from the SAN on-prem to Azure?
Also in case of failback how is it done or is it possible in the first place ?

@Anonymous Host SAN is supported by our VMware machine protection scenario using ASR - https://learn.microsoft.com/azure/site-recovery/vmware-physical-azure-support-matrix#storage. Replication will happen to Azure storage – managed disks. Failback is also supported, and the user can failback to either the original location or an alternate location.

Azure Site Recovery is the solution.

Yes, it is possible. Refer to the doc - https://learn.microsoft.com/en-us/azure/site-recovery/vmware-azure-failback

Hi @Anonymous

Thank you for asking this question on the **Microsoft Q&A Platform. **

You don't need to replicate the SAN per se.

You should focus on replicating each VM with their disks.

If you have a failback, you just activate the failover of your VM's on Azure

Hope this helps,
