A full backup is a complete copy of all data from a specific system or storage device. This type of backup captures everything, including files, applications, and system settings, ensuring that all information is preserved in one operation. It serves as a comprehensive snapshot, making it easier to restore the entire system if needed. Performing a full backup is essential for data protection and recovery. It is often used in conjunction with other backup types, such as incremental backups or differential backups, to create a robust data management strategy. Regular full backups help safeguard against data loss due to hardware failure, accidental deletion, or cyber threats.
