Backup Hidden Recovery Partition on Windows 10, 8, 7 - How?

What is a hidden recovery partition anyway?

If you take a closer look at your hard drive, you may find that it has less space than it should. When you open Disk Management to examine it, you will see a recovery or OEM partition that is taking up a lot of space on your hard drive. What is this recovery partition and OEM partition?

Many computer manufacturers will create a recovery partition that will take up a few gigabytes to a dozen more space. These recovery partitions allow you to reset your computer to its factory default settings by pressing a specific key. During the installation of Windows 10/8/7, Windows also creates a recovery partition that you can use to use recovery options if your computer runs into problems.

Windows recovery partition is much smaller than the factory recovery partition so you don't mix them up. In general, Windows 10 recovery partition is 450MB, Windows 8 is 350MB, and Windows 7 is 200MB.

There are certain circumstances where you need to temporarily delete the recovery partition, such as: For example, if you want to add unallocated space to the system drive, the hidden recovery partition will prevent this operation. In this case, you will need to back up the recovery partition if you still want to restore the factory settings. In addition, the hard drive could fail, so backing up the recovery partition is necessary for those who will be able to restore to the factory default settings.

How to backup the recovery partition

The Windows built-in backup tool "Backup and Restore" can only contain the partitions with a drive letter in the backup. Since the recovery partition is hidden by default without a drive letter, you cannot use the "Backup and Restore" function to back up the factory recovery partition, but You can use Wbadmin to perform the command line backup by using Volume GUID to specify the hidden recovery partition.

To secure with Wbadmin:

1. Open an elevated command prompt with administrator privileges.

2. Write a backup command that refers to the following syntax:

Wbadmin start backup –backuptarget: [backup location] –include: [drive letter or volume GUID] \? \ Volume {95b895b8-0000-0000-0000-40f30d000000} \

If you don't know the volume GUID, run the mountvol command.

For example, Wbadmin start backup –backuptarget: G: –include: \? \ Volume {95b895b8-0000-0000-0000-40f30d000000} \

After you run the command, Wbadmin will start the backup immediately. It seems pretty convenient, but if either the recovery partition or the backup destination location partition is not formatted with NTFS, you will get the error resulting in the backup failed. In this case, you need to use free third-party software.
