The ABC Company runs two shifts, from 8:00 am to midnight. Backups and system maintenance are performed between midnight and 8:00 am. For each of the following scenarios, determine whether the company’s current backup procedures enable it to meet its recovery objectives, and explain why:
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
Scenario 2: Company makes daily incremental backups Monday through Friday at 3:00 a.m. each night. Company makes full backup weekly, on Saturdays 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
Scenario 3: Company makes daily differential backups Monday through Friday at 3:00 a.m. each night. Company makes full backup weekly, on Saturdays, at 1:00 p.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
