For each of the following scenarios, determine whether the company’s current backup procedures enable it to meet its recovery objectives and explain why:
a. Scenario 1:
Recovery point objective = 24 hours
Daily backups at 3:00 am, process takes 2 hours
Copy of backup tapes picked up daily at 8:00 am for storage off-site
b. Scenario 2: Company makes daily incremental backups Monday-Saturday at 7:00 pm each night. Company makes full backup weekly, on Sunday at 1:00 pm.
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
c. Scenario 3: Company makes daily differential backups Monday-Friday at 8:00 p.m. each night. Company makes full backup weekly, on Saturdays, at 8:00 am.
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
