Lance Whitney / Elyse Betters Picaro / ZDNETZDNET’s key takeawaysWindows has a hidden backup tool in Windows 10 and 11.It can save files to discs, drives, or network locations.Deprecated by Microsoft, so expect occasional errors.Regularly backing up your files is always a good idea, just in case any important or irreplaceable ones go missing. For that, you can turn to a variety of programs. But Windows itself has a built-in backup tool that’s simple and flexible. The catch is that you probably don’t even know it exists.Named simply Windows Backup, this feature lets you choose which folders and files to back up. You can back up only select files or all your Windows folders. You’re supposed to be able to include an entire system image in the backup in case you ever need to restore Windows in full. The limitation here is that you can’t save the system image on removable media. But you can always use the system image tool to do this separately.

You can also set the backup to run on a regular basis. The tool works the same in Windows 10 and 11. But as always, there is a hiccup here. This version of Windows Backup has since been deprecated by Microsoft, which means it’s no longer supported or updated. As a result, you could bump into issues and errors when using the tool. In my experience, it generally works reliably. However, the last few times I tried using a network share as my backup destination, I received an error that the specified network location cannot be used. Although I confirmed that the network path, credentials, and other settings were correct, I continued to get the same error. I’ve seen posts from other Windows users complaining of the same problem. Your mileage may vary, but keep this in mind when choosing your backup destination. Also: Your Windows 11 PC has a secret emergency shutdown feature – here’s how to use itTo add to the mystery, Microsoft offers a newer tool also known as Windows Backup. (Yes, Microsoft loves to use the same names across different products to confuse people.) The newer Windows Backup is designed to back up and restore certain files and settings. The main objective is to help you move from one PC to another. In contrast, the older legacy Windows Backup that I’m covering here operates more like traditional backup software. Both tools serve their purpose. But here’s how the older, legacy Windows Backup works and how to use it to back up anything you want, to any location you want. More
