Q

Recovery Point Objective (RPO)

A

A recovery point objective (RPO) is the period for which recent data will be irretrievably lost in a disaster.

2
Q

Extend of acceptable data loss

A

It’s called Recovery Point Objective or RPO.

RPO POINT is most concerned by data loss

3
Q

RPO measures

A

RPO is usually measured in hours or days.

4
Q

Recovery Time Objective

A

Recovery time objective (RTO) is the period from the onset of an outage until the resumption of service.

5
Q

Extend of acceptable system downtime

A

It’s called Recovery Time Objective or RTO

RTO Time is for system downtime.

6
Q

RTO measures

A

RTO is usually measured in hours or days.

7
Q

What a RTO of 2 hours indicates

A

that organization needs to ensure that their system downtime should not exceed 2 hours.

8
Q

What a RPO of 2 hours indicates

A

that organization needs to ensure that their data loss should not exceed 2 hours of data captured.

9
Q

What should a RTO for a critical system be

A

Zero or near Zero

10
Q

What should a RPO for a critical data be

A

Zero or near Zero

11
Q

The lower RTO or RPO

A

The higher the cost of maintenance environment

12
Q

What a low RTO or RPO indicates

A

That disaster tolerance is low. Therefore, if disaster tolerance is low, RTO/RPO should be low.

13
Q

What is recommended when RTO is low

A

A mirrored site or hot site

14
Q

What is recommended when RPO is low

A

Mirror imaging or real time replication for data back-up is recommended

15
Q

What is recommended when RPO is zero

A

Synchronous data backup strategy to be used

16
Q

The lower the time requirements for RTO & RPO

A

The higher, the cost of recovery strategies.
