A backup is a digital copy of your most important information
Copies of your files (e.g. photos, documents, videos, etc.) are saved to an external storage device or to an online server like the cloud.
Backing up and having backups mean you can restore your files if something goes wrong. It is a precautionary measure so that your data is accessible in case something happens to your computer. We recommend backing up your files regularly.
You can set up automatic backups in your system or application settings for peace of mind
