Which disaster recovery site can become operational in hours or days?

A warm site is a type of disaster recovery site that is equipped with the necessary hardware and software to allow it to become operational relatively quickly, usually within hours or days. This site is not as immediately ready as a hot site, which is fully operational at all times, but it has enough resources in place to ensure a shorter recovery time compared to a cold site. Cold sites typically require significant setup time to bring everything online since they have no active equipment or data preloaded. Offsite storage primarily focuses on keeping backups of data and does not provide the infrastructure needed to quickly resume operations. Therefore, the warm site strikes a balance by having essential components ready to facilitate faster recovery while still requiring some configuration or setup time.
