Which technology should be included in the disaster recovery plan to prevent data loss?

In the context of a disaster recovery plan, the inclusion of offsite backups is crucial for preventing data loss. Offsite backups ensure that a copy of data is stored in a different physical location from the primary site, safeguarding against local disasters such as fires, floods, or other catastrophic events that could compromise all data stored on-site. By maintaining data redundancy in a remote location, organizations can recover their crucial information quickly and efficiently in the event of data loss.

This approach not only protects against hardware failures and human error but also aligns with best practices for data integrity and availability. Regularly scheduled backups, combined with offsite storage, enable organizations to restore operations with minimal downtime and data loss, thereby enhancing overall resilience.

Other options, while they serve their respective purposes, do not directly prevent data loss in the same way offsite backups do. For instance, locked racks enhance physical security but do not protect against data loss due to disasters. Video surveillance can aid in monitoring and securing locations but does not address the actual preservation of data. Meanwhile, system patches are critical for maintaining security and preventing vulnerabilities, but they are not directly related to backing up or protecting data in the event of an incident.
