Hyper-V

You can use the Commvault software to back up and restore VMs that are hosted on a Hyper-V cluster or a standalone Hyper-V server. You can configure a hypervisor to represent a Hyper-V cluster, a Hyper-V server in a cluster, or a standalone Hyper-V server.

Backups

Data You Can Back Up

  • Hyper-V VMs (powered on or powered off)

  • VHD and VHDX files

  • Snapshot files

  • Configuration files for the VMs

  • Metadata required for granular recovery of files (NTFS and ext3 volumes only)

  • VHDX formatted hard disks with sector size of 4K bytes without metadata

  • Hyper-V replica VMs that are stopped

Data You Cannot Back Up

  • Pass-through disks

  • Hard links (only for disk-level backup)

  • Virtual machine smart paging files

  • Certain virtual machines in which Volume Shadow Copy Service (VSS) fails to create a shadow

  • Devices residing in a guest virtual machine over iSCSI or vHBA

  • Hyper-V replica VMs that are running

  • Page and swap files (Hyper-V Integration Services must be installed on guest VMs)

  • VM folders with compression enabled

    When a virtual machine resides on a VM folder that has compression enabled, backups of that virtual machine fail. However, manual snapshots of the virtual machine complete.

Backups You Can Perform

  • Full backups

  • Incremental backups

  • Synthetic full backups

  • Streaming backups

  • IntelliSnap backups

  • Backup copy

  • Application-aware backups

When You Can Perform Backups

  • On a schedule: The server plan that you assign manages scheduled backups

  • On demand: You can perform on-demand backups at any time

Restores

Restores You Can Perform

  • Guest files and folders

  • Full virtual machines

  • Disk files

  • Live Recovery

  • Live Mount

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

  • Hyper-V hypervisors

  • AWS instances

  • Azure destinations

  • VMware destinations

  • Azure Stack Hub destinations
