Data backups are copies of important information stored separately from the original data. They are created to protect against data loss due to hardware failures, accidental deletions, or cyberattacks. By having a backup, individuals and organizations can restore their data to a previous state, ensuring continuity and security. There are various methods for creating data backups, including using external hard drives, cloud storage services, or dedicated backup software. Regularly updating backups is essential to ensure that the most recent data is saved. This practice helps safeguard valuable information, such as documents, photos, and software applications.
