How low are you willing to CybeRTO and CybeRPO? Part 3 of 3


Data RecoveryIn the first part of this series, we discussed CybeRTO (Sigh-Ber-To) and CybeRPO (Sigh-Ber-Po) and the general meanings of both.  In the second part of the series, we took a deeper look at the two different ways to address the particular aspects of CybeRTO.  In the third and final part of this series we’re going discuss CybeRPO, and identifying the point in time you’ll be recovering from in the event of data loss from a cyber attack. Another way to look at it is, how much data will I lose after a cyber attack has occurred?

In most cases, CybeRPO mainly pertains to servers and end-user computing devices though it could affect networking and security devices. In all cases having a backup of the data in question is the first step. The next question is at what point was the last backup taken?

When discussing servers, CybeRPO can be a very low number or a much higher number depending on how often the data in question is backed up.  Do you just need the ability to recover files or might you need to recover an entire physical or virtual server?   The more often the data is backed up the lower the CybeRPO.  Solutions can be designed to have the backups occur as files or servers as a whole are changing which drives the CybeRPO down very low.  On the flip side, backups can happen on a daily or weekly basis which will cause CybeRPO to be quite high.

End-user computing devices, specifically laptops, and desktops are similar to servers but in some cases, the entire device does not need to be backed up and only the user files need to be backed up.  Many organizations use imaging software to create base images of the end user devices so when a cyber attack affects the end user devices they blow away everything that was on the device and send a new image down to the device.  Wi
