Why do data backup?

Data backup can be a very wide range which includes system backup, partition backup, file and folder backup. Data loss can be caused by many reasons. For instance: system corruption, disk crash, computer viruses, or catastrophic events like floods, earthquakes, virus and robberies of your home or office.

Sometimes it will give you a critical strike if you are responsible for business data, a loss may involve critical financial, customer, and company data. It is also disasters if you lose some personal files like pictures with family which can not be replaced, music with high expense. So you should backup those precious data in advance in case something bad happens. This passage will introduce 2 ways of data backup using cmd.

Create data backups with Wbadmin command

Wbadmin start backup Creates a backup using specified parameters. It applies to Windows Vista, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012 R2, Windows Server 2012, Windows 8.

Step 1. Click “start”, in the Search box, type cmd, and then right-click cmd, and select Run as administrator.

Run As Administrator

Step 2. To backup data using command prompt, you can use the command “wbadmin start backup -backuptarget:{|} -include:-allCritical”. So if you want to create backup of C: and E: to an external hard drive (D: drive), use this command: wbadmin start backup -backuptarget:D: -include:C:,E: -allCritical.


There are also many other syntax for Windows PC that you can choose. 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. 

What’s more, Windows only support several functions, sometimes it cannot satisfy your needs. In this case, you may look for a way to use one simple command to backup hard drive from command line.
