The purpose of information backup is to ensure the availability and recoverability of critical data in case of data loss, system failures, or disaster events. As an auditor, I would review these pieces of evidence to assess the organization's backup procedures, data integrity, and the effectiveness of their backup strategy in safeguarding against potential data loss and ensuring business continuity
