Full Backup
A full backup is a data backup method that copies all selected files, folders, and system data from a source to a backup destination, creating a complete snapshot of the data at a specific point in time. It serves as a comprehensive recovery point, allowing restoration of the entire dataset in case of data loss, corruption, or disaster. This method is foundational in backup strategies, often used in combination with incremental or differential backups for efficiency.
Developers should learn and use full backups when setting up initial backup systems, performing periodic complete snapshots (e.g., weekly or monthly), or ensuring reliable disaster recovery for critical systems like databases, servers, or application data. It is essential in scenarios requiring full system restoration, compliance with data retention policies, or as a baseline for more complex backup schemes, providing a straightforward and reliable recovery option.
