What is the difference between a backup plan and a disaster recovery plan?
A backup plan answers what is copied, how often, where it is stored and for how long. A disaster recovery plan answers how you get the business running again when something big breaks: who decides, which systems come back first, where they run if the original site or hardware is gone, how long each step may take, how staff and customers are informed, and how you know you are finished. Backups are one ingredient of recovery, not the whole recipe. Companies with excellent backups still lose weeks after a ransomware attack because nobody knew the restore order, the backup console needed a domain that no longer existed, or the only person who knew the passwords was on holiday. Write the recovery plan down, keep a copy outside your own systems, including on paper, and test it with a realistic exercise at least once a year, just as you test restores.
