Storage Rules help create a mapping between an Azure Region and your chosen Druva Cloud Storage. Once you identify the Azure SQL resources to be protected within a specific Azure Region, the Storage Rule directs the data backups to the appropriate Storage Region provisioned for that subscription. In other words, use storage rules to direct specific backups to the appropriate storage.
📝 Note
You will need to configure storage rules to get started with protecting your Azure SQL resources. Any backup configuration will be executed only when a corresponding Storage Rule is available.
Precedence criteria
A unique storage mapping takes precedence over mappings set at a broader level, as illustrated by the following scenarios:
Scenario 1: Two storage rules are defined, one with All regions (default) mapped to Druva-Cloud-Storage-1, and a more specific rule, for example, Ireland (EU) mapped to Druva-Cloud-Storage-2.
Azure SQL resources within Ireland (EU) region therefore will be mapped to Druva-Cloud-Storage-2 since a specific storage rule exists for resources in that Azure Region.
Azure SQL resources in other regions, for example east-us will be backed up to Druva-Cloud-Storage-1. In this case, the default mapping will apply, in the absence of a more specific rule.
Scenario 2: Any new unique mappings will only apply to new Azure SQL resources configured for backup. Azure SQL resources that have already been backed-up based on an existing rule will continue to move based on the original rule.
📝 Notes
Once a storage rule has been defined, the Azure SQL resources within that region are permanently assigned to that Druva Storage. Resources within that Azure Region will continue to be backed up to the Storage assigned.
Any changes to an existing rule will only apply to resources configured for backup thereafter.
You can define multiple storage rules. Ensure that you adhere to your organizational compliance and governance policies. when assigning a storage rule.
Create storage rules
To define storage rules:
Log into the management console.
Navigate to the Storage Rules listing page.
The list of rules defined for your Azure account is displayed.Click Manage Storage Rules.
On the Manage Storage Rules section, click Add to create a new storage rule.
Select the Azure Region and Map to the appropriate Druva Storage. This directs all backups in the selected Region to the Storage assigned here. In the Map to Backup Storage dropdown:
If only Azure Storage is provisioned, you’ll see the Azure storage options supported by Druva.
If only AWS Storage is provisioned, you’ll see AWS storage options.
If both Azure Storage and AWS Storage are provisioned, options for both will appear.
For more information about Cloud storage, see About Cloud storage.
You may also choose to edit the mapping for an existing rule.
However, you cannot edit the storage mapping for the All regions (default) rule.
Click Save.
📝 Note
Any changes to an existing rule will only apply to resources configured for backup thereafter.
About Cloud storage
You can store your backup data to Druva-supported regions in Azure Storage, AWS Storage, or both. To configure your storage type, contact your Account Manager.
On the Management Console > Storage Rules page, you can map a region to storage based on the storage type that you have provisioned. For example, if you have provisioned Azure Storage, you will see Druva-supported Azure Storage region options in the Map to Backup Storage dropdown. If you have opted for both AWS Storage and Azure Storage, you will see both of these storage options in the Map to Backup Storage dropdown.
For more information on how to map a region to a storage, see Create storage rules.
