Hyper-V Granular restore

This section explains how to perform a Hyper-V Granular Restore using a System Protection, File Protection or File Archiving backup. Hyper-V Granular Restore allows you to restore individual files from a guest using a Hyper-V backup of one or more guests.

This feature requires the Hyper-V Advanced add-on.

ClosedShow : Hyper-V with Exchange Granular

Restoring mail items into an Exchange Server on a Hyper-V guest requires both the Exchange Granular add-on and a Hyper-V Advanced add-on license.

The Hyper-V Granular Restore tool will automatically mount the guest so that Exchange Granular Restore can restore mail items into it.

ClosedShow : Data container considerations

System Protection backups can use Data containers as backup destinations. BackupAssist automatically mounts Data containers when restores are performed. However, there may be times when you want to do this manually. For example, if you want to check what is inside a Data container or have it available for another task.

To manually mount a Data container:

  1. Open Disk Management.

    2. For Windows Server 2008 R2, SBS 2011 and Windows 7

    1. Click the Start button.
    2. Type diskmgmt.msc into the Search Programs and Files text box.
    3. Click OK.

    For Windows Server 2012 and Windows 8 and later

    1. Open Run from the Apps screen.
    2. Type diskmgmt.msc into the Search Programs and Files text box.
    3. Click OK.

    The Disk Management console will open.

  2. Select Action from the Disk Management menu.
  3. Select the menu option Attach VHD.
  4. Enter the path of the Data container that you want to mount and click OK.

    5. You will now have a drive named BA_VHD_Container in your list of available drives.

  5. Right click BA_VHD_Container, select Change Drive Letter and Paths, and select Add.
  6. Select a drive letter for the Data container, using the drop down box, and select OK.

    Hyper-V Granular Restore : Search

    The Search feature supports File Protection and System Protection backups.

    When you select the Search button, the Search screen will appear.

    Backups section

    Allows you to use the Jobs filter, to limit the search to specific backup jobs. You can also use the Backup date filter to search within a specified date range.

    Search section

    Enter a search term associated with the name of the file you want to find. The Search for field will take the string provided and search for occurrences of that string in a file or directory name. The results of the search are displayed by backup.

    Refine the search

    You can refine your search using the Search section’s Created, Modified and Size options. Ticking any of these options will activate a drop down list of variables to select from. For Created and Modified, you can select a date using the Calendar selection fields. For Size, you can select the file size in bytes.

    To perform a restore, select the files that you want to restore and select the Restore button.

    Note: To be able to use the Search feature for Hyper-V guest backups, the backups must be cataloged. A backup will only be cataloged if it is created by a backup job that has the Catalog Hyper-V Guests option enabled.

    Cataloging the Hyper-V guest is enabled by Editing the backup job in the Manage menu as follows:

    • For a File Protection backup select Catalog Hyper-V Guests under Replication Options.
    • For a System Protection backup select Catalog Hyper-V Guests under Imaging Options.

    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.

    • 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.

    1. Use the Browse button to locate and select the restore destination.
    2. Use the drop down box to set the overwrite rules. The overwrite rules will apply if the files being restored encounter files with the same name in the restore destination.
      • Overwrite existing files: the restored files will overwrite files in the restore destination.
      • Do not overwrite existing files: the restored files will not overwrite files in the restore destination. This means the files will not be restored.
      • Only overwrite older files: if a source file has changed since the backup was made it will not be overwritten.
    3. Review the Restore NTFS security attributes option

      4. If you select this option, the NTFS security attributes the file had when it was backed up will be retained when the file is restored. The NTFS security attributes can be viewed in the Security tab on the file’s Properties

    BitLocker Encrypted backups

    If your backup is encrypted, you will be prompted for the encryption password when the restore job accesses the backup. You can also use the encryption key to unlock an encrypted drive, by connecting the USB flash drive. BackupAssist will use the key to unlock the drive you are restoring from. You will not be prompted to do anything other than the normal restore steps.

    Note: It is important that you keep a copy of your password in a safe place, as we cannot assist you with opening password-encrypted files if your password is lost or forgotten.

  8. Select Done

    9. Once the restore has finished, selecting Done will return you to the main UI.

Your Hyper-V Granular restore has now been completed.
