Granular Restore of Individual Files in Backed Up VM

Before you proceed with the Granular Restore, make sure the following dependencies are fulfilled on the restore machine. Failure to do so may cause the granular restore to fail.

1). Microsoft Visual C++ 2015 Redistributable (x86) / (x64)
https://www.microsoft.com/en-us/download/details.aspx?id=48145

2). Update for Universal C Runtime in Windows
https://support.microsoft.com/en-us/help/2999226/update-for-universal-c-runtime-in-windows

3). Microsoft Security Advisory 3033929 (for Windows 7 and Windows Server 2008 R2)
https://technet.microsoft.com/en-us/library/security/3033929.aspx

Requirements and Limitations

  1. Granular restore does not support the mounting of virtual disks, if the disk itself is encrypted, for example using Windows Bitlocker or other third party security features.

  2. If any folders or files on a virtual disk are encrypted, these files/folder cannot be supported with Granular Restore. For example, if the “Encrypt contents to secure data” is selected in Advanced attributes.

  3. The mounting of Linux/Unix file systems from virtual disk file is currently not available due to limitations of the file system drivers.

  4. Granular restore can only be performed on one guest VM at a time with no limitation on number of virtual disk that can be mounted on the guest VM, however, only files/ folders from one virtual disk can be retrieved at a time.

  5. Windows User Account Control (UAC) must be disabled to apply granular restore.

Restore Procedures

1. Click the Restore icon on the main interface of CloudBacko Go

2. Select the backup set that you would like to restore the individual files from.

3. Select the backup destination that contains the VM that you would like to restore.

4. Select to the Restore individual files in virtual machine (Granular Restore) option.

The Mount virtual disks automatically option is selected by default. If the guest VM contains a multiple virtual disks and you only require the restore of files from a single or certain virtual disk(s), then unselect this option to speed up the virtual disk mounting. Otherwise, granular restore will connect and mount all available virtual disks and this process could take longer.

You may select the Read timeout limit by clicking Show advanced option.

This selection defines the duration when the granular restore session will be disconnected if there is no response from the mounted virtual machine.

  • Default – This setting should be suitable for guest VMs located on a local, removable, or network drive. The time out value is 15 seconds.
  • Unlimited – the connection will not time out when this is selected. This selection is recommended when:
    • Backup destination is a cloud storage.
    • A large guest VM or guest VM with large incremental delta chain.

If in doubt or unsure about the guest VM size or network stability, it is recommended to use Unlimited.

Click Next to proceed when you are done with the selection.

5. The following screen will be shown when you perform Granular Restore for a backup set on this machine for the first time only. Make sure you click Install to confirm starting the installation of the drivers on this machine. Clicking No will exit the restore process.

6. Select the virtual machine that you would like to perform Granular Restore for, then click Next to proceed.

7. Select a temporary directory for storing restore files, then click Restore to start the Granular Restore.

8. When the virtual disk(s) are in the process of being prepared for mounting on the CloudBacko Go machine, you will see the following screen.

Please wait as the process could take some time depending on the size of the virtual disk, network bandwidth, and storage location.

9. Select the drive where you wish the mounted image to be mapped on your machine then click OK to proceed.

10. If the Mount virtual disks automatically option is unselected then click on the disk icon to mount the virtual disk you wish to restore files from.

Otherwise, all the virtual disks will be automatically mounted.

11. When the virtual disk is mounted, you will see the following screen showing the information of the mounted virtual disk with the available volume shown.

There are two options to restore individual files from here.

Option 1: Restore Using CloudBacko Go File Explorer

This method allows you to use the file explorer in CloudBacko Go to browse through the files from the mounted virtual disk and select files you wish to restore.

i. Click to browse the files in the mounted virtual disk. If there are multiple volumes in the guest VM, you can only select one volume to restore individual files at a time.

You will then see a file explorer menu as shown below. Select the file(s) you wish to restore, then click Next to proceed.

Some system folder(s) / file(s) (e.g. System Volume Information) are only shown in the CloudBacko Go File Explorer and will not be restored, therefore, those folder(s) / file(s) will not be shown in the mapped drive shown in step iv below.

ii. Select a path where you wish the files to be restored to, then click Restore.

iii. The following screen shows when the selected files have been restored to the defined destination.

iv. Open the defined restore path and you should be able to see the files restored there.

Option 2: Restore Using Windows File Explorer

This method allows you to browse through the files from the mounted virtual disk through the Windows File Explorer on the machine where you have CloudBacko Go installed on.

Granular Restore of VMware backup sets performed using Windows File Explorer will not generate restore log on CloudBacko Go.

i. Click and then you will be prompted to select a driver letter where you wish the mounted backup image to be mapped on your machine, click OK when you have finished selecting.

ii. The selected drive letter will be mapped and prompted in the Windows Files Explorer with the files you wish to restore shown.

iii. You can now click on the files to view them directly from here, which will be in read-only mode, or copy them to your local machine.

Viewing the files directly is enabled only if the source application is already installed on the machine. i.e. “MS Word” must have already been installed for viewing the “.doc” file.

iv. The mounted drive letter cannot be ejected from the Windows File Explorer, and it will only be closed when you exit CloudBacko Go.

12. When you have finished restoring the necessary files, you can go back to CloudBacko Go and click on Cancel.

13. Then click on Stop the granular restore and unmount the virtual disk(s).

Due to the limitation of the virtual file system library, the mounted virtual disks will only be unmounted from your machine when you exit CloudBacko Go.
