After a company experienced a localized disaster, the Business Continuance Plan was reviewed. The plan was revised to include a Recovery Time Objective (RTO) of four (4) hours and a Recovery Point Obj

Mirrored snapshots of data and applications provide near-instantaneous recovery points, supporting the 1-hour RPO, and enable very quick restoration of data and applications, which is essential for a 4-hour RTO.

Recovering backup tapes from offsite storage is a time-consuming process involving transport and restoration, making it incompatible with both a 4-hour RTO and a 1-hour RPO.

Data snapshots from the previous day would result in an RPO of at least 24 hours, failing to meet the specified 1-hour RPO.

Operating system and application reinstallation from media is a lengthy process that would make achieving a 4-hour RTO extremely difficult, if not impossible.

A hot or warm site provides pre-configured, readily available infrastructure, significantly reducing the time required to bring operations back online after a disaster, which is critical for meeting a 4-hour RTO.
