A company's primary data center is located in a region prone to earthquakes. A security administrator is tasked with implementing a backup strategy to ensure data can be recovered even if the data center is completely destroyed. Which of the following backup strategies would be the MOST effective in mitigating this specific risk?
Back up data to tapes and store them in a fireproof safe located in the same building.
Implement RAID-6 arrays for all critical servers onsite.
Store encrypted backups at a geographically separate, offsite location.
Create daily snapshots stored on a separate storage area network (SAN) within the same data center.
Storing encrypted backups at a geographically separate, offsite location is the most effective strategy. This approach ensures that if a physical disaster like an earthquake destroys the primary data center, a complete copy of the data is safe and available for recovery at a different location. Onsite solutions like RAID or local snapshots would be destroyed along with the data center, and a fireproof safe in the same building would not protect against the building's collapse.
