Why each option
The GFS (Grandfather-Father-Son) backup strategy is a common rotation scheme that defines how backups are retained over different time periods.
Greatest, Final, Sequential is not a recognized backup term or standard, nor does it describe the GFS method.
Full, Partial, Incremental describes types of backups, not a specific retention rotation scheme like GFS.
The GFS backup method is named for its retention policy which typically includes daily (Son), weekly (Father), and monthly (Grandfather) backups, rotating media sets accordingly. This hierarchical retention strategy ensures data recovery points are available for varying historical durations.
Full, Differential, Incremental describes common backup types, but does not represent the GFS backup rotation strategy.
