Why automatic backup Windows 10 to external hard drive
We backup our computers to ensure the safety of valuable data and information. And based on the 3-2-1 backup strategy, local disk should not be our only choice of backup destination: We can backup Windows 10 to external hard drive as a double insurance, while backing up files to OneDrive, Google Drive, NAS, etc. as an offisite copy.
In such strategy, the main benefits of external hard drives (or USB flashes drives) as target devices are convenience and portability. But if you don't make backups in a timely manner, you may only be able to retrieve outdated versions of data after it is lost or corrupted, which can be quite frustrating.
For users who value efficiency, it's clearly better to set up an automated backup task rather than perform the same operation over and over manually. In the following article, I will use Windows 10 as an example to explain how to automatically backup computer to external hard drive.
