The ABC Company is considering the following options for its backup plan:
1. Daily full backups:
.Time to perform backup = 60 minutes
. Size of backup = 50 GB
Time to restore from backup = 30 minutes
2. Weekly full backups plus daily incremental backup:
.Same time, storage, and restoration as above to do a weekly backup on Friday, plus
Time to perform daily backup = 10 minutes
Size of daily backup = 10 GB
Time to restore each daily backup file = 5 minutes
3. Weekly full backups plus daily differential backup:
.Same time, storage, and restoration as above to do a weekly backup on Friday, plus
Time to perform daily backup = 10 minutes first day, growing by 5 minutes each day thereafter
Size of daily backup = 10 GB first day, growing by 10 GB each day
Time to restore differential backup file = 5 minutes first day, increasing by 2 minutes each subsequent day
Which approach would you recommend? Why?
