Protecting Azure Virtual Machines with Commvault

You can use the Commvault software to back up and recover Microsoft Azure VMs.

Backups

Data You Can Back Up

  • VMs (Windows and Linux, powered on or powered off).

  • VMs of any security type (standard, trusted launch, and confidential).

  • VMs of Azure Generation 1 and Azure Generation 2.

  • For Azure Resource Manager deployments, VMs that are configured with Azure unmanaged and managed disks. From these backups, you can restore full VMs and guest files and folders.

  • Disks that are configured by users through the Azure portal, including disks that are configured on Standard and Premium storage accounts.

  • VMs that are encrypted by Azure Key Vault.

    Backups of these VMs can include the operating system information, the data disks information, secrets (for example, token and password information), and encryption keys (for example, algorithm information). The encryption keys can be managed by Microsoft or by customers.

  • Azure managed disks that are 8 TB or smaller.

  • For Azure-managed disks, information about the configured Availability Zones, which are specific (physical) locations within an Azure region.

  • Azure-managed disks that are enabled with encryption at the host.

  • Proximity placement groups.

  • If the source VM is associated with an application security group, then the application security group is included in the backup.

Data You Cannot Back Up

  • Temporary disks that are automatically configured by Azure when a VM is created.

  • Files or network drives that are shared in Azure and mounted on a VM.

  • Azure Ultra SSD-managed disks.

    Due to a Microsoft limitation, snapshots of Ultra SSD-managed disks are not supported. When Ultra SSD-managed disks reside on a VM with other supported disks, during backups, the Ultra SSD-managed disks are skipped. The other disks on the VM are backed up.

    You can back up your Ultra SSD-managed disks using the Commvault Windows File System Agent.

  • Managed Premium V2 SSD disks.

Backups You Can Perform

  • Full backups

  • Full backups, using IntelliSnap

  • Incremental backups

  • Synthetic full backups

Restores

Restores You Can Perform

  • Full VMs

  • Guest files and folders

  • Attaching disks to an existing VM

  • VM files

Backups You Can Use for Restores

  • The most recent backup: For example, restore the most recent backup to its original location

  • A backup from a specific date: For example, restore data to a point in time before it became unusable

  • Backups from a date range: For example, restore data that was accidentally deleted

Destinations You Can Restore To

  • The current location (in place)

  • A different VM (out of place)
