If Azure Databricks will be deleted by someone and which contains Notebooks as well. So, if we want to recover that databricks along with notebooks , is it possible? If so please explain how we can achieve this type of condition.
If you are looking to prevent deletion, you can set Azure Resource locks. Specifically you can set the CanNotDelete lock. This lock means authorized users can still read and modify a resource, but they can't delete the resource.
Some Azure services, such as Azure Databricks, use managed applications to implement the service. In that case, the service creates two resource groups. One resource group contains an overview of the service and isn't locked. The other resource group contains the infrastructure for the service and is locked. You should lock the resource containing the service to prevent accidental deletion.
If you try to delete the infrastructure resource group, you get an error stating that the resource group is locked. If you try to delete the lock for the infrastructure resource group, you get an error stating that the lock can't be deleted because it's owned by a system application.
