A full backup backs up all data in the selected folders, partitions, or hard disks, whether or not the data has been backed up before. In other words, it always backs up all data in the selected locations. A full backup is also the basis for incremental and differential backups. After creating a full backup, you can use incremental or differential backup modes to save time on subsequent backups.
You can start a full backup directly from the Backup and recovery page by clicking Backup --> Full backup.
