It's always good to have a backup, as can be seen from our other articles in the knowledge base. It is vital to keep copies of your files on another drive in case something happens to the originals. If you don't already have backup software on your computer system, use the following information to get started:

Select the Start button, then select Settings  > Update & security > Backup > Add a drive and choose an external drive or network location for your backups.

All set. Every hour, Windows 10 will back up everything in your user folder (C:\Users\username). To change which files get backed up or how often backups happen, go to More options.

To restore your backed up files:

If you’re missing an important file or folder, here’s how to get it back:

1. Search for Restore files from the taskbar and select Restore your files with File History.

2. Look for the file you need and then use the arrows to see all its versions.

3. When you find the version you want, select the Restore button to save it in its original location. To save it in a different place, right-click (or press and hold) the Restore button, select Restore to, and then choose a new location.
