Which backup method is recommended to avoid introducing vulnerabilities?

The recommended backup method to avoid introducing vulnerabilities is the indirect backup. This approach typically involves creating copies of data without directly engaging with the critical systems or data in a way that could expose them to vulnerabilities. In indirect backups, data is often collected from the systems and stored in a separate location, which minimizes the risk of exposing sensitive data during the backup process.

This method can utilize various tools and techniques that effectively isolate the data being backed up, ensuring that the operational integrity of the production environment is maintained. By not directly backing up from the live environment, indirect backups can help prevent potential threats, such as malware or data corruption, from affecting the backup itself.

Other backup methods, like direct, incremental, or full backups, may involve more risk if not handled carefully, as they often interact closely with production data. In contrast, indirect backups are designed to mitigate these aspects, making them a safer choice in terms of reducing the introduction of vulnerabilities during the backup process.
