Which backup strategy involves a hot site and mirrored systems?

The strategy that involves a hot site and mirrored systems is characterized by its capability to provide immediate operational continuity in the event of a disaster. A hot site is a fully equipped backup location that can take over operations almost instantly, with systems already in place that mirror the primary site. This means that data is continuously updated in real-time or near real-time, ensuring that the transition to the hot site can occur with minimal downtime.

Implementing a hot site is particularly crucial for organizations that cannot afford significant interruptions, as it ensures that business functions can continue seamlessly. The mirrored systems aspect adds an extra layer of resilience by maintaining a duplicate of the primary system, thus safeguarding against data loss and enabling quick recovery.

Other site options, such as a cold site or warm site, do not provide the same level of immediate disaster recovery. While a cold site may have facilities ready for use, it does not include active technology or data, requiring significant time and resources to make operational. A warm site has some technology and backup resources but is not as instantly operational as a hot site. Therefore, the answer that accurately describes the backup strategy involving a hot site and mirrored systems is indeed the hot site.
