A. B. C. D.C.
The GFS backup standard stands for "Grandfather-Father-Son" and it is a popular backup strategy used to balance between retention of historical backups and efficient use of storage space. This backup method is designed to ensure that multiple copies of data are maintained in different locations and on different storage media to protect against data loss due to hardware failure, human error, or disaster.
The GFS backup strategy involves three different levels of backups:
Full backup: This is the initial backup that copies all the data in the system to the backup location. The full backup is usually performed on a weekly basis, but it can also be done on a daily or monthly basis depending on the organization's requirements.
Incremental backup: This backup only copies the changes made to the data since the last full backup. Incremental backups are performed daily and require less storage space than full backups, making it an efficient method for routine backups.
Differential backup: This backup copies all the changes made to the data since the last full backup, but unlike incremental backups, it does not rely on the previous backup. This method is performed periodically and can be used to create a "father-son" relationship, where the differential backup serves as the "son" and the full backup serves as the "father".
Therefore, option D. Full, Differential, Incremental describes the GFS backup method as it includes all the three levels of backup involved in the GFS strategy.
