During any audit, regulations are the most important factor and guidelines for what must be tested. Although the requirements from management, stakeholders, and shareholders are also important, regulations are not negotiable and pose the biggest risk to any organization for compliance failure.

In order to ensure compliance with regulations, it is important for an organization to regularly test the restorability of archived data. As technologies change and older systems are deprecated, the risk rises for an organization to lose the ability to restore data from the format in which it is stored.
With the destroy, store, and share phases, the currently used technologies will be sufficient for an organization's needs in an ongoing basis, so the risk that is elevated with archived data is not present.

Release management involves planning, coordinating, executing, and validating changes and rollouts to the production environment. Change management is a higher-level component than release management and also involves stakeholder and management approval, rather than specifically focusing the actual release itself. Availability management is focused on making sure system resources, processes, personnel, and toolsets are properly allocated and secured to meet SLA requirements. Problem management is focused on identifying and mitigating known problems and deficiencies before they occur.

Explanation
When a security professional is considering cloud solutions for BCDR, a top concern is the jurisdiction where the cloud systems are hosted. If the jurisdiction is different from where the production systems are hosted, they may be subjected to different regulations and controls, which would make a seamless BCDR solution far more difficult.
