Off-site storage involves storing data backups in a physically separate location from where the servers and primary data reside. This protects critical data in case the main site is damaged or destroyed due to a natural disaster, such as floods, fires, or earthquakes. Off-site storage can be in the form of cloud storage or physical tapes stored in a geographically distant location.
* Off-site storage (Answer A): It ensures that a company's critical data remains accessible even if the local infrastructure is compromised. This is a common part of disaster recovery planning and is crucial for business continuity.
* Life-cycle management (Option B): While important for managing data from creation to deletion, it does not specifically protect data during disasters.
* Environmental controls (Option C): These manage physical conditions like temperature and humidity but do not address the risk of data loss during disasters.
* Data-at-rest encryption (Option D): Encryption protects the confidentiality of stored data but does not ensure availability in the event of a disaster.
