What defines a mirrored site in cybersecurity?

A mirrored site in cybersecurity refers to a backup site where the data and systems are replicated in real-time or near real-time. This means that the primary site’s data is duplicated at the mirrored location, so that in the event of a failure, outage, or disaster, operations can switch seamlessly to the mirrored site with minimal disruption. The key aspect of a mirrored site is its role as a robust and reliable alternative for data backup, ensuring that the information can be quickly restored and accessed.

Mirroring typically involves continuous data synchronization, which distinguishes it from other types of backup solutions that may only perform periodic updates. This ensures that the mirrored site always has an up-to-date copy of the data, thus safeguarding against data loss.

This definition aligns well with the concept of disaster recovery and business continuity, emphasizing the importance of having a dependable data backup strategy to handle unforeseen incidents effectively.
