Before You Begin

Before you perform Instant VM Recovery, consider the following:

  • You can restore a machine from a backup that has at least one successfully created restore point.
  • If you restore a machine to the production network, make sure that the original machine is powered off to avoid conflicts.
  • If you want to scan machine data for viruses, check the secure restore requirements and limitations.
  • You must have at least 10 GB of free disk space on the vPower NFS datastore to store virtual disk updates for the restored VM.

By default, Veeam Backup & Replication writes virtual disk updates to the NfsDatastore folder on a volume with the maximum amount of free space, for example,  C:\ProgramData\Veeam\Backup\NfsDatastore. The vPower cache is not used when you choose to redirect virtual disk updates to a VMware vSphere datastore in the Instant VM Recovery wizard.

  • Finalizing Instant VM Recovery using Veeam Quick Migration with Smart Switch requires at least the amount of instantly recovered VM RAM settings plus 200 MB of free disk space in vPower NFS cache location to suspend the VM state to disk. For example, if the restored VM has 32 GB of virtual RAM, 32.2 GB of free space is required. This is not a requirement when you are using vSphere Storage vMotion instead.
