Archived release notes in Azure Backup

This article lists all the past releases of features and improvements from Azure Backup. For more recent and up to date releases, see What's new in Azure Backup.

Release summary

Azure Disk Backup (in preview)

Azure Disk Backup offers a turnkey solution that provides snapshot lifecycle management for Azure Managed Disks by automating periodic creation of snapshots and retaining it for a configured duration using backup policy. You can manage the disk snapshots with zero infrastructure cost and without the need for custom scripting or any management overhead. This is a crash-consistent backup solution that takes point-in-time backup of a managed disk using incremental snapshots with support for multiple backups per day. It's also an agent-less solution and doesn't impact production application performance. It supports backup and restore of both OS and data disks (including shared disks), whether or not they're currently attached to a running Azure virtual machine.

For more information, see Azure Disk Backup (in preview).

Encryption at rest using customer-managed keys

Support for encryption at rest using customer-managed keys is now generally available. This gives you the ability to encrypt the backup data in your Recovery Services vaults using your own keys stored in Azure Key Vaults. The encryption key used for encrypting backups in the Recovery Services vault may be different from the ones used for encrypting the source. The data is protected using an AES 256 based data encryption key (DEK), which is, in turn, protected using your keys stored in the Key Vault. Compared to encryption using platform-managed keys (which is available by default), this gives you more control over your keys and can help you better meet your compliance needs.

For more information, see Encryption of backup data using customer-managed keys.

Azure Resource Manager template for AFS backup

Azure Backup now supports configuring backup for existing Azure file shares using an Azure Resource Manager (ARM) template. The template configures protection for an existing Azure file share by specifying appropriate details for the Recovery Services vault and backup policy. It optionally creates a new Recovery Services vault and backup policy, and registers the storage account containing the file share to the Recovery Services vault.

For more information, see Azure Resource Manager templates for Azure Backup.

Incremental backups for SAP HANA databases (in preview)

Azure Backup now supports incremental backups for SAP HANA databases hosted on Azure VMs. This allows for faster and more cost-efficient backups of your SAP HANA data.

For more information, see various options available during creation of a backup policy and how to create a backup policy for SAP HANA databases.

Backup Center (in preview)

Azure Backup has enabled a new native management capability to manage your entire backup estate from a central console. Backup Center provides you with the capability to monitor, operate, govern, and optimize data protection at scale in a unified manner consistent with Azure’s native management experiences.

With Backup Center, you get an aggregated view of your inventory across subscriptions, locations, resource groups, vaults, and even tenants using Azure Lighthouse. Backup Center is also an action center from where you can trigger your backup related activities, such as configuring backup, restore, creation of policies or vaults, all from a single place. In addition, with seamless integration to Azure Policy, you can now govern your environment and track compliance from a backup perspective. In-built Azure Policies specific to Azure Backup also allow you to configure backups at scale.

For more information, see Overview of Backup Center.

Back up Azure Database for PostgreSQL (in preview)

Azure Backup and Azure Database Services have come together to build an enterprise-class backup solution for Azure PostgreSQL (now in preview). Now you can meet your data protection and compliance needs with a customer-controlled backup policy that enables retention of backups for up to 10 years. With this, you have granular control to manage the backup and restore operations at the individual database level. Likewise, you can restore across PostgreSQL versions or to blob storage with ease.

For more information, see Azure Database for PostgreSQL backup.

Selective disk backup and restore

Azure Backup supports backing up all the disks (operating system and data) in a VM together using the virtual machine backup solution. Now, using the selective disks backup and restore functionality, you can back up a subset of the data disks in a VM. This provides an efficient and cost-effective solution for your backup and restore needs. Each recovery point contains only the disks that are included in the backup operation.

For more information, see Selective disk backup and restore for Azure virtual machines.

Cross Region Restore for SQL Server and SAP HANA (in preview)

With the introduction of cross-region restore, you can now initiate restores in a secondary region at will to mitigate real downtime issues in a primary region for your environment. This makes the secondary region restores completely customer controlled. Azure Backup uses the backed-up data replicated to the secondary region for such restores.

Now, in addition to support for cross-region restore for Azure virtual machines, the feature has been extended to restoring SQL and SAP HANA databases in Azure virtual machines as well.

For more information, see Cross Region Restore for SQL databases and Cross Region Restore for SAP HANA databases.

Support for backup of VMs with up to 32 disks

Until now, Azure Backup has supported 16 managed disks per VM. Now, Azure Backup supports backup of up to 32 managed disks per VM.

For more information, see the VM storage support matrix.

Simpler backup configuration for SQL in Azure VMs

Configuring backups for your SQL Server in Azure VMs is now even easier with inline backup configuration integrated into the VM pane of the Azure portal. In just a few steps, you can enable backup of your SQL Server to protect all the existing databases as well as the ones that get added in the future.

For more information, see Back up a SQL Server from the VM pane.

Back up SAP HANA in RHEL Azure virtual machines (in preview)

Azure Backup is the native backup solution for Azure and is BackInt certified by SAP. Azure Backup has now added support for Red Hat Enterprise Linux (RHEL), one of the most widely used Linux operating systems running SAP HANA.

For more information, see the SAP HANA database backup scenario support matrix.

Zone redundant storage (ZRS) for backup data (in preview)

Azure Storage provides a great balance of high performance, high availability, and high data resiliency with its varied redundancy options. Azure Backup allows you to extend these benefits to the backup data as well, with options to store your backups in locally redundant storage (LRS) and geo-redundant storage (GRS). Now, there are additional durability options with the added support for zone redundant storage (ZRS).

For more information, see Set storage redundancy for the Recovery Services vault.

Soft delete for SQL Server and SAP HANA workloads

Concerns about security issues, like malware, ransomware, and intrusion, are increasing. These security issues can be costly, in terms of both money and data. To guard against such attacks, Azure Backup provides security features to help protect backup data even after deletion.

One such feature is soft delete. With soft delete, even if a malicious actor deletes a backup (or backup data is accidentally deleted), the backup data is retained for 14 additional days, allowing the recovery of that backup item with no data loss. The additional 14 days of retention for backup data in the "soft delete" state don't incur any cost to you.

Now, in addition to soft delete support for Azure VMs, SQL Server and SAP HANA workloads in Azure VMs are also protected with soft delete.

For more information, see Soft delete for SQL server in Azure VM and SAP HANA in Azure VM workloads.
