data backup

**Data Backup**

Data backup refers to the process of creating copies of important digital information to prevent loss due to hardware failure, accidental deletion, cyberattacks, or other unforeseen events. Regular data backup ensures that critical files, databases, and system configurations can be restored quickly, minimizing downtime and maintaining business continuity. Common backup methods include full, incremental, and differential backups, which can be stored on local drives, external media, or cloud services. Implementing a robust data backup strategy is essential for safeguarding data integrity and reducing the risk of permanent data loss.
