In which of the following media rotation schemes are daily, weekly, and monthly backup media utilized in a first-in, first-out method?

Grandfather-father-son (GFS) is a common backup rotation scheme that uses daily, weekly, and

monthly backup media in a first-in, first-out (FIFO) method. The daily backups are rotated on a 3-

months basis using a FIFO system as above. The weekly backups are similarly rotated on a bi-yearly

basis, and the monthly backups are rotated on an annual basis. The oldest backup media in each

cycle are overwritten by the newest ones. This scheme provides multiple versions of backup data at

different intervals, allowing for flexible restoration options. Waterfall is another name for GFS.

Synthetic full is a backup method that combines an initial full backup with subsequent incremental

backups to create a new full backup without transferring all data again. Tower of Hanoi is another

backup rotation scheme that uses an algorithm based on moving disks between three pegs.
