The objective is to protect against a disaster, thus the DR site should be far enough away so that it will not be affected by the same disaster (like making sure that your backup power is carried over different lines and your backup network connection is in a different cable, etc.) It also depends on which disasters your company can recover from, and what the recovery would be. For example, if your single factory was destroyed, what would be the plan? Rebuild, or take the insurance and run?
