Which method provides continuous data protection within a network?

The method that provides continuous data protection within a network is real-time processing. This approach ensures that data changes are captured and stored immediately as they occur. By continuously monitoring and recording all transactions or modifications, real-time processing minimizes the risk of data loss and maintains an up-to-date repository of information. This immediacy and constant updating allow organizations to recover from data loss incidents more quickly and efficiently, providing robust protection against unforeseen data-related issues.

In contrast, other methods like synchronous replication involve replicating data to another site in real-time but may not encompass all forms of data or cover the same extent as real-time processing. Asynchronous backup, while useful, introduces time gaps between data changes and the backup, which could lead to data loss during those intervals. Lastly, periodic backups operate on a schedule, capturing data at specific intervals, which leaves windows where changes are not protected until the next backup occurs.
