disk backup

Disk backup is a process of copying and saving the data stored on a computer's hard drive to another storage device or location. This ensures that if the original data is lost, damaged, or overwritten, a recent copy is available to restore the information quickly. Think of it as making a digital safety deposit, allowing you to recover important files like documents, photos, or software if something unexpected happens to your computer. Regular backups help protect against data loss from hardware failures, viruses, or accidental deletion, keeping your information secure and accessible.
