Instant Recovery of Hyper-V 2016 VMs with Backup Exec 16.

Instant Recovery of Hyper-V 2016 VMs with Backup Exec 16.

What is Instant Recovery?

Instant Recovery (IR) is a rapid recovery technique that starts the virtual machine directly from the backup set located on Backup Exec storage. This saves the time required to copy the data over the network to the hypervisor host.

How does this feature work?

  1. A virtualized copy of the backup(s) is made available to the virtualization host via an SMB (Hyper-V) share.
  2. The virtualization host creates a VM from the backup copy.
  3. To handle the writes to the instantly recovered VM, a snapshot is taken for the newly created VM.
  4. Reads of existing data happen from the virtualized copy on the Backup Exec server.
  5. The backup set and related dependencies are marked as retained to prevent Data Lifecycle Management (DLM) grooming.
  6. User can optionally choose to migrate the instantly recovered virtual machine Backup Exec server storage to faster storage that is directly attached to the Hyper-V host.
