Summary
This article describes an important update to Azure Backup for Microsoft Azure Recovery Services (MARS) Agent version to 2.0.9262.0, that is used both by Microsoft Azure Backup and the Microsoft Azure Site Recovery service to transport data to Azure.
Important improvements
This update includes two new features to improve the resiliency of the Recovery Services Agent.
Save MARS agent passphrase securely to Azure Key Vault is now generally available.
MARS Agent from Azure Backup requires a passphrase provided by the user to encrypt the backups sent to and stored on Azure Recovery Services Vault. This passphrase is not shared with Microsoft and needs to be saved in a secure location to ensure that the backups can be retrieved if the server backed up with MARS goes down.
You can now save the MARS passphrase securely to Azure Key Vault from the console during a new registration or a change passphrase operation. Learn more.
Addition security for operations
If you have security settings for on-premises backups on in the vault, with MARS version 2.0.9262.0 and later, the operations of removing a volume from MARS file/folder backup, adding a new exclusion setting for an existing volume, reducing retention duration, and moving to a less-frequent backup schedule are also protected with a security pin for additional security. Learn more.
Note: These preview features are not yet enabled for System Center Data Protection Manager (DPM) & Microsoft Azure Backup Server (MABS).
Apart from the new features mentioned above, this update includes the following changes:
-
Ability to view expiry time and retention type for all recovery points.
-
From the MARS agent console, go to Status Pane, under Available Recovery Points click View Details to list all available recovery points.
-
-
Ability to stop protection and retain data by policy.
-
This option will stop all future backup jobs from protection. Learn more.
-
Azure Backup service will continue to expire existing recovery points according to the policy configured.
-
You'll be able to restore the backed-up data for unexpired recovery points. If you decide to resume protection, then you can use the Re-enable backup schedule option. After that, data will be retained based on the new retention policy.
