Full VM Recovery

A Full VM Recovery uses a backup of a guest to recover that guest to a Hyper-V host. This will return the guest and its operating system, applications, data and services, to a previous working state. You can recover the guest to its original location, overwriting the existing guest, or to a different location on the host. You can also recover the guest’s VHD (virtual hard drive) to a different Hyper-V host and use that VHD to create a new guest.

ClosedShow : Requirements

Full VM Recovery requirements:

  • Full VM Recovery supports System Protection, File Protection and File Archiving backups.
  • The host server the guest is being recovered to must have at least 4GB of memory available – which will be used by the recovered guests.
  • A guest can only be recovered to a Hyper-V Host that runs the same version of Windows Server (or higher) as the original Hyper-V host.

  • To see the BIOS, O/S and hardware requirements for both physical and virtual system recoveries, see the Recovery Reference sheet.

ClosedShow : Recovery to a CSV

When a guest is successfully restored to a Hyper-V cluster shared volume (CSV), it will become available on the Hyper-V machine that it was restored to.

  • If the restore replaces the existing guest, the CSV settings will be retained and the guest will be added back to the cluster.
  • If the restore does not replace the existing guest, the CSV setting will need to be manually configured to add the guest to the cluster.

  1. Select the Recover tab
  2. Select Full VM Recovery

    Recover tab

    This is one of 4 recovery options available. If the guest is needed urgently and you have the Hyper-V Advanced add-on, a Rapid VM Recovery would be performed. The Full VM Recovery could then be performed at a convenient time.

  3. Select the guest.

    4. Select the guest that you want to recover from the list of backed up guests. When you make a selection, the screen will reload and display all available backups of that guest.

    Virtual Machine selection

    If you have a non-VSS guest backup, use the Restore tab’s Hyper-V Host Files option to restore the guest VHD to the host, and use the VHD to create a new guest.

    The Full VM Recovery screen can also show guests backed up from other machines added using the Discover Backups button.

    The Discover Backups option allows you to add and restore from backups created by other installations of BackupAssist and backups made by local jobs that have been deleted.

    Discover backups

    When you select the Discover Backups button, the Discover Backups screen will appear.

    • If you select Show manually added backups, backups from other BackupAssist installations that were added using the + option will be available when you go back to the main restore screen.
    • If you select Show backups made by deleted jobs, backups made by deleted backup jobs will be displayed and available when you go back to the main restore screen.
    • If you select Show backups made by existing jobs, only backups made by the current list of local backup jobs will be shown. This is the default list you saw before using the Discover Backups option.
    • Selecting the plus symbol will open a browse dialog that can be used to locate backups made by other BackupAssist installations and add them to the Discover Backups screen.
    • Selecting the cloud symbol will open a dialog from where you can select and configure the cloud destination that you want to restore from. This option allows you to restore from a backup created on another machine or a deleted job.
    • Selecting Delete, removes any selected backups that were added using the + option.

    Selecting only one of these options means only those backups will be shown when you go back to the main restore screen. Combinations of these 3 options can be selected to get the set of backups that you want.

  4. Select the backup

    5. Select the backup that you want to use for the recovery. The tabs can be used to filter the backups shown. Selecting a backup will open BackupAssist'sIntegrated Restore Console.
