An administrator has found that a server has become corrupted. Which of the following will allow the administrator to recover the data?

A Server UPS (Uninterruptible Power Supply) rack provides temporary power during outages and protects against power fluctuations, but it does not protect against data corruption or allow for data recovery.

Off-site backups are copies of data stored at a separate geographical location, providing resilience against local disasters, hardware failures, or server corruption. In the event of server corruption, restoring data from a recent off-site backup is the most reliable way to recover lost or damaged information.

OS restore disks are used to reinstall or repair the operating system, but they typically do not contain or restore user data, which is the primary concern for recovery after corruption.

Redundant NICs (Network Interface Cards) provide fault tolerance for network connectivity, ensuring the server can communicate even if one NIC fails, but they do not protect or recover data from corruption.
