As the GFS backup scheme forces automatic deletion of the outdated backups, on the first Friday of 
the second year the tapes keep only the backups displayed in the next figure. 
 
This figure demonstrates that the GFS Example 2 tape rotation scheme is more suitable for the case 
than  GFS Example 1. The advantages of the GFS Example 2 tape rotation scheme for the analyzed 
case are the following: 
• 
it uses 16 tapes instead of 25 
• 
a data recovery task requires one (25%) or two (75%) tapes 
• 
data recovery from a full backup requires only one tape that makes the data recovery from an 
incremental or differential backup faster. 
 
GFS Example 3 
Imagine the backup plan has the following tape options: 
• 
the Use a separate tape set option is selected 
• 
the Always use a free tape: For each full backup option is selected 
• 
the Always use a free tape: For each incremental backup option is selected 
• 
the Always use a free tape: For each differential backup option is selected.
