Which is a key benefit of data backup?

A key benefit of data backup is that it ensures data is recoverable after an event. This means that in the event of data loss caused by a system failure, accidental deletion, or a cyberattack, having a backup allows organizations or individuals to restore their data to a previous state. This capability is crucial for minimizing downtime and maintaining business continuity. Proper data backups protect against unforeseen events that could otherwise lead to costly data loss and the potential disruption of operations.

Additionally, while other options may touch on important aspects of data management or system performance, they do not capture the primary purpose and advantage of data backups in terms of data safety and integrity. The primary goal of backing up data is to secure it against loss, making recoverability the most critical benefit.
