Which backup rotation strategy is best suited for ensuring both data redundancy and efficient storage use?
Monthly Differential Backups
Daily Incremental Backups
Grandfather-Father-Son (GFS)
Weekly Full Backups
The Grandfather-Father-Son (GFS) rotation scheme is optimal because it maintains multiple layers of backups, providing sufficient redundancy while allowing for efficient use of storage. This method includes daily backups (Son), weekly backups (Father), and monthly backups (Grandfather), ensuring that past versions are accessible while minimizing the space required for keeping duplicate data.
Other options may not effectively balance redundancy and storage efficiency, leading to potential data loss or excessive space usage.
