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.
