OLD SCHOOL THINKING Midnight The day before Midnight 3:00 pm 11:59 pm RPO Recovery Point Objective Failure RTO Recovery Time Objective Recovery Point + Recovery Time = your REAL downtime A failure occurs at 3pm How Long until I fix the problem? How old is my data? 15 hours? How long until I can restore from tape? Did the backups run correctly? This is your Recovery Point 39 hours? How long until users are back on? This is your Recovery Time Leaders Have Vision visionsolutions.com 3
THE NEW STANDARD Midnight 3:00 pm 11:59 pm Failure RPO RTO Downtime is reduced from hours/days to seconds/minutes A failure occurs at 3pm How long until users are back on? Minutes How old is my data?
