Hi Sammy - For DR solution in Azure, I would recommend to go with Manged DR Tools like ASR (Azure site recovery manager) for replication and orchestration.
There are multiple factors to consider when you planning for DR testing. Its all depends on your requirements.
Key things to consider:
- Define your RPO and RTO
- How you want the DR testing to be done in Azure. Like Live testing(with redirecting networks and etc) or just bubble testing (bring the VMs in isolated network in Azure and see if the VMs are just coming up or not and close the testing). You need to some kind of runbook for your DR for the execution.
- AD Restore in DR is tricky, the recovery model might change based on above points.
using cloudberry or other static backup tools. it more like taking backup of azure vm and restore in Azure, its more like a backup and not a functional DR solution.
consider tools like ASR as part of your DR strategy to get the complete operation benefits.
