GFS Rotation Scheme
The GFS (Grandfather, Father, Son) rotation scheme is considered a minimum
standard for backing up important data.
A full backup is performed weekly (Father).
This is coupled with a daily incremental or differential backup (Son).
This allows a restore to any day of the week.
A monthly backup is also performed (Grandfather).
Thus backups for a year would require 23 tape sets.
12 Monthly (Grandfather)
4 Weekly (Father)
7 Daily (Son)
Some of the monthly tape sets should be stored off site in case a catastrophic
failure occurs.
For further information on doing production level backups and restores,
