ISO 270001 standard implementation

For ISO 27001 certification, a disaster recovery site is necessary only if you have relevant risks that are reduced to acceptable levels by implementing this approach, or if there are legal requirements (e.g., laws, regulations or contracts) demanding the implementation of this site.

If none of the above-mentioned conditions apply, then you do not need a disaster recovery site to be certified.
