Learn how to use Wbadmin start backup all drives to create a complete disk backup including the hidden partitions without drive letter in Windows 10/8/7 and Windows Server 2008/2008 R2/2012/2012 R2.

Wbadmin start backup all drives

For many programs have rights to write data to your hard disk, and some data are not stored in file or folder type, some users may want to back up their entire hard disk to keep all information backed up. In Windows Server, you can use Windows Server Backup to manually add all drives in the backup. However, Windows Backup and Restore (for PC) only allows you to add drives with a drive letter in a backup except critical volumes. Actually both Windows PC users and Server users can use Wbadmin utility to backup an entire disk from command line. Although Microsoft doesn’t provide a wbadmin backup disk full switch, you can use –include: [drive letter] switch to add all drives in the backup. For the drives without drive letter, you can use volume GUID when specifying drives.

How to backup an entire disk with Wbadmin?

To use Wbadmin, you need to open an elevated command prompt with administrator privileges. You can type “CMD” in the search box, right click the top listed results, and click Run as administrator. Then run the following command:

wbadmin start backup -backuptarget:{<BackupTargetLocation> | <TargetNetworkShare>} -include: <ItemsToInclude> -allCritical

For example, to create a computer backup including C: drive, D: drive, E: drive, and recovery partition to a shared folder over NAS, use the following command:

wbadmin start backup -backuptarget:\\192.168.0.221\Public\backup -allCritical -include:C:,D:,E:,\\?\Volume{95b895b8-0000-0000-0036-223470000000}\

Backup to NAS

For the recovery partition does not have a drive letter, you must use volume GUID to specify this drive. You can use “mountvol” command to get the volume GUID information.

If you do not want to be prompted to run the backup, you can add the –quiet switch. To backup an entire disk containing system reserved partition, C: drive, E: drive, and recovery partition to an external hard drive (F: drive), use this command:

wbadmin start backup -backuptarget:F: -include:C:,E:,\\?\Volume{d4192b6f-0000-0000-0000-804c0c000000}\ -allCritical –vssCopy -quiet

Running this command, the backup will start right away without prompt. The –vssCopy switch is not necessary because it makes no difference on the items included in the backup.

If you have too many partitions on one disk that you want to backup, to specify the partitions one by one, not to mention the hidden partitions, would be cumbersome. In this case, you may look for a way to use one simple command to backup hard drive from command line.
