DR versus disaster avoidance
Disaster avoidance, as the name implies, is the process of preventing or significantly reducing the probability that a disaster will occur (through human errors), or ensuring that if such an event does occur (as in natural disaster) then the effects upon the organization's technology systems will be minimized as much as possible. The idea of disaster avoidance provides better resilience rather than good recovery, but to do so, you cannot rely only on infrastructure availability solutions, which are mostly geographically limited to a specific site; you also need to look at how to provide better application availability and redundancy in the wake of foreseeable disruptions.
