Answer
A usable disaster recovery plan includes recovery priorities, system and application startup order, contact paths, network and access prerequisites, external dependency checks, communication steps, and named decision owners for each major action. Backups matter, but they are only one part of getting the business operating again.
Buyers should ask whether the software supports that wider recovery design with status visibility, documentation, and testability. If the plan only answers where the saved data lives, it is not yet a full disaster recovery plan.
