Secondary site location

Answer:

There is no standard distance for a secondary site, because this distance depends on primary site location, organization's profile, and many other variables. You can consider these factors to define the distance most adequate to your business:
- the impact radius of a disruption event that can hit your site (the greater the impact, the longer the distance of your secondary site)
- the costs related to keep this secondary site available (e.g., the greater the distance, the greater the cost of telecommunication links used to connect both sites, and costs to move personnel from the site in case of need).
