Why each option
The monthly backups in a tape backup scheme are referred to as "Grandfather" backups as part of the Grandfather-Father-Son (GFS) rotation strategy.
"Great-grandfather" is not a standard term in the GFS backup rotation scheme.
In the Grandfather-Father-Son (GFS) backup rotation strategy, the "Grandfather" backups are typically the oldest, most comprehensive, and least frequent, corresponding to monthly or annual backups that are retained for a significant duration. This scheme ensures data recovery options spanning different timeframes while optimizing tape usage.
"Father" backups in the GFS scheme refer to weekly backups, which are less frequent than daily but more frequent than monthly.
"Son" backups in the GFS scheme refer to daily backups, which are the most frequent and have the shortest retention period.
