Requirement for DR site

Most regulations and industry practices do not define any specific distance to recovery sites, because many factors can affect what would be considered a “safe” distance (e.g., type of disaster, access to public services, risk level, etc.). From our experience, we suggest you start a discussion about the distance of the DR site suggesting a distance between 30 miles (50 kilometers) and 100 miles (160 kilometers) away from your primary location and from that analyze your organization's context (a geographic situation, available resources, required investment, etc.).
