Grandfather-father-son backup (GFS) is a common rotation scheme for backup media, [1] in which there are three or more backup cycles, such as daily, weekly and monthly. 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 backup on a yearly ...
The repository could be as simple as a list of all backup media (DVDs, etc.) and the dates produced, or could include a computerized index, catalog, or relational database. The backup data needs to be stored, requiring a backup rotation scheme, [4] which is a system of backing up data to computer media that limits the number of backups of ...

The two resulting child buckets will themselves split when they become full, so the database grows ...

A level 1 backup taken on Monday would include only changes made since Sunday. A level 2 backup taken on Tuesday would include only changes made since Monday.
