Recovery Point Objective (RPO) (Col 5)
The point in time before a disaster to which system and data must be recovered.
The recovery point objective (RPO) is the age of files that must be recovered from backup storage for normal operations to resume if a computer, system, or network goes down due to a hardware, program, or communications failure.
- In layman's terms, it can be defined as how much data you need to recover in the event of a disruption
- Speak to your IT team and ask when the data is usually backup. If it is 10 pm every night and the disaster happens at 1 pm the following day, you will lose the data from 10 pm last night to 1 pm this afternoon. It will add up to 13 hours.
System Recovery Time Objective (Col 6)
The period of time within which systems and applications must be recovered after a disruption has occurred in order to carry out the recovery of business functions.
System Recovery Time Objective refers to the maximum acceptable length of time that can elapse before an IT application needs to be brought back up. It should not exceed the RTO of the Business Function attached.
- How long does the IT team or vendor "promise" to bring your system up once it is disrupted? Is it stated in their service level agreement (SLA)?
- Within what period of time must the system be recovered after the disruption?
Supporting Special Equipment or Resources (Col 7)
