To Create a System Image Backup
Connect the External HDD and check for the Drive Letter (in this case its” E :”) .Also makes sure that the back-up drive has more storage room than the space used of your C: drive.
Right click Start menu and select Windows PowerShell (admin) ,Click yes to the User Account Control if prompted
In the powershell enter the following command:
wbAdmin start backup -backupTarget:E: -include:C: -allCritical –quiet
Note: The above command tells the Windows to back up the C: drive onto the E: drive, including all critical volumes containing the system’s state. The -quiet switch tells the cmdlet to run without prompting you.
