22.4. Defining the Recovery Process
There are a lot of tools that can help with disaster recovery, but an effective recovery process circles back to having a well-defined plan of what to do in every scenario. Two things, at least, need to be clearly identified:
- What signals a disaster? Some things are obvious (a massive power outage, network loss, or fire), but other situations need to be defined. For example, what signals that a backup server needs to be brought online?
- Who responds to a disaster and how? Once a disaster situation occurs, who has the responsibility to act? How are they notified of the event? What are they expected to do?
- Store a printed copy off the disaster recovery plan off-site.
- Test the disaster recovery plan on a regular basis and after configuration and infrastructure changes.
