Syncing important files like documents and photos to OneDrive is a great way to keep them safe. Backing them up to an external hard drive is a good idea, but your external drive is usually kept in the same location as your PC. So, if there’s a fire or natural disaster or a robbery, it’s just as likely you’ll lose your external drive and the data stored on it. When information is backed up to the cloud, it’s stored offsite, usually in multiple locations. Should something happen to your computer, you can open up another device, log onto your OneDrive account, and access your files.
I find it convenient to be able to access the same files from my desktop, laptop, and phone. To pick which files you want to backup, you can right-click on your OneDrive icon on the Taskbar or on OneDrive in File Explorer and choose Settings.
Click the Backup tab.
You’ll see an option to automatically save photos and videos to OneDrive when you connect a camera or phone to your PC and to Automatically save screenshots to OneDrive. I’d be cautious about ticking these boxes if you save a lot of high-resolution photos and are using only the 5 GB of storage space. If you tick that box, keep an eye on how much you’re uploading.
Click Manage backup to select the files you wish to sync between your computer and the cloud.
Select the folders you want to backup and click on Start backup.
