Understanding disaster recovery terminology

The terminology surrounding disaster recovery can be daunting and confusing for those who are not in the know, so to help business leaders brush up on their understanding, Tech Target has published a breakdown of the meaning of some of the most common terms.

Data recovery planning is essential for businesses to ensure they have the right processes in place to weather the storm when disaster strikes. Failure to properly plan for such eventualities could lead to failure for a business in general, so it pays to have an understanding of disaster recovery from the ground up.

Recovery point object or RPO is the first term businesses should be aware of, as this relates to the maximum permissible amount of time that can pass before a business is back up and running following a crisis event.

In terms of the practicalities of this, if a file is given an RPO of one day, then backups for the data should be made at least every 24 hours, meaning that in the event of disaster the time taken to recover lost data will not exceed the amount of downtime suffered.

Meanwhile, recovery time objective or RTO relates to the maximum amount of time specific systems or technologies can be out of action for in the event of a crisis.

Failover is a term that will often be talked about in disaster recovery circles and in its most basic form, this generally means a backup operational mode for systems that can be implemented when primary systems go offline.

Finally, the term disaster recovery itself should be addressed, as this should be seen not only as the sequence of events that come into action when a crisis takes place, but all the preparation training and understanding of responsibilities that needs to take place to be adequately prepared ahead of any emergency.
