Chapter 10, Problem 10P

For each of the following scenarios, determine whether the company's current backup procedures enable it to meet its recovery objectives, and explain why:

1. a. Scenario 1:
   • Recovery point objective = 24 hours
   • Daily backups at 3:00 A.M., process takes 2 hours
   • Copy of backup tapes picked up daily at 8:00 A.M. for storage off-site
2. b. Scenario 2: Company makes daily incremental backups Monday through Saturday at 7:00 P.M. each night. Company makes full backup weekly, on Sunday at 1:00 P.M.
   • Recovery time objective = 2 hours
   • Time to do full backup = 3 hours
   • Time to restore from full backup = 1 hour
   • Time to make incremental daily backup = 1 hour
   • Time to restore each incremental daily backup = 30 minutes
3. c. Scenario 3: Company makes daily differential backups Monday through Friday at 8:00 P.M. each night. Company makes full backup weekly, on Saturdays, at 8:00 A.M.
   • Recovery time objective = 6 hours
   • Time to do full backup = 4 hours
   • Time to restore from full backup = 3 hours
   • Time to do differential daily backups = 1 hour on Monday, increasing by 30 minutes each successive day
   • Time to restore differential daily backup = 30 minutes for Monday, increasing by 15 minutes each successive day
