Storage Rules help create a mapping between Druva Cloud and your AWS resources within specific Regions and Accounts. Once you identify the AWS resources to be backed up to Druva Cloud, the Storage Rules direct the data backups to the appropriate Druva Cloud Region provisioned within your chosen Account. 

In other words, use storage rules to direct specific resource backups to the appropriate Druva Cloud Storage.

Note

  • You will need to configure Storage Rules to get started with backing up snapshots to Druva Cloud.
  • A backup policy defined to move snapshots to Druva Cloud will be executed only when a corresponding Storage Rule is available.

Create storage rules

To define storage rules:

  1. Log into your Druva CloudRanger console and navigate to the Account for which you wish to configure storage rules. Click the gear icon on the top navigation bar.
  2. Click Druva Cloud to be directed to the Druva Storage page.

  3. On the Storage Rules tab, click Add.
    • Select the Account and AWS Region to filter resources to be backed up from.
    • Select the Druva Storage name to assign the storage for all backups generated from the resources filtered within the selected Account and Region.

How Storage Rules apply on Druva CloudRanger:

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 within the same Account (Account A), one with All Regions and one with Ireland (EU). In this case, the storage rule with Account A; Ireland (EU) will take precedence over the Account A; All Regions rule.

Scenario 2: A rule set to Account A; All Regions will take precedence over a broader rule defined as All Accounts; All Regions.

Note: Once a storage Region has been defined, pre-existing backups cannot be moved to a new Region.

Delete storage rules

Once defined, you may delete a storage rule, as needed. However, do consider the business implications and storage costs prior to deleting a storage rule associated with an active backup policy.

Note: Once a resource has been backed up to a Storage provisoned on Druva Cloud, the backups will continue to reside within that storage, even if the associated storage rules are modified or deleted.

To delete a storage rule:

  1. Log into your Druva CloudRanger console and navigate to the Account for which you wish to configure storage rules. Click the gear icon on the top navigation bar.
  2. Click Druva Cloud to be directed to the Druva Storage page.
  3. On the Storage Rules tab, select the storage rule to be deleted. Click Remove
    On the confirmation screen, verify the storage rule that you wish to delete. Click Confirm, delete.

Next steps

Once you define storage rules,  proceed with setting up your Client Credentials to enable access to your AWS Key Management System (AWS KMS) to generate and manage the data encryption key (ekey). The ekey once generated is used to encrypt the user data that is then backed up to Druva Cloud. To get started with ekey management, you will need to import the relevant credentials to your Druva CloudRanger account. For more information, see Manage Client Credentials.

Alternatively, you may want to set up a backup policy to automate your data protection strategy and manage the backup schedules and retention. Once defined, backup policies can be executed across AWS accounts at the organization level, and set to Active or disabled, depending on business requirements. For more information, see Setup Policy to Backup Snapshots to Druva Cloud.
