An IS auditor's primary concern would be whether the recovery site devices can handle the storage requirements. The storage requirements are determined by the amount and type of data that needs to be backed up and restored in case of a disaster at the primary data center. The recovery site devices should have enough capacity, performance, reliability, and compatibility to meet these requirements.
If the recovery site devices cannot handle the storage requirements, then there is a risk that some data may not be backed up properly or may not be available for recovery when needed. This could result in data loss, corruption, or inconsistency, which could affect the business continuity and integrity of the organization.
Therefore, an IS auditor should verify that:
* The recovery site devices have sufficient storage space to accommodate all the data that needs to be backed up from the primary data center.
* The recovery site devices have adequate bandwidth and speed to transfer and access data efficiently and effectively.
* The recovery site devices have appropriate security features and controls to protect data from unauthorized access or modification.
* The recovery site devices are compatible with the primary data center devices in terms of hardware, software, format, and protocol.
