Backup and restore is a process used to protect and recover data. A backup involves creating a copy of important files, documents, or system settings, which can be stored on external drives, cloud services, or other storage devices. This ensures that if data is lost due to accidental deletion, hardware failure, or cyberattacks, it can be retrieved. The restore process allows users to recover their data from these backups. When a system or file is compromised, users can access their backup to restore the lost information to its original state. This practice is essential for maintaining data integrity and security.
