Each has its benefits, and each has its drawbacks. By combining
the two, you get the fast failover capabilities of database mirroring and the ability to
have data stored at multiple locations (mirroring only permits one mirror database).
Basic Documentation for Disaster Recovery
Having a disaster recovery plan is important to even the smallest organization. However,
an undocumented disaster recovery plan is next to useless. In addition to the specific
steps to be taken in the event of a failure (from a technology point of view), a disaster
recovery plan must include basic, logistical information.
There are also some caveats when it comes to documentation. Some of these will seem
obvious to the point of being silly, but I can tell you from experience that they happen:
??? Don??™t rely on electronic documentation only: You should always have a hard copy of
the plan available. What happens if you lose power to your facility? A hard copy of
the plan can be invaluable. Also, be sure to update it on a regularly scheduled basis.
??? Don??™t store the documentation on the server that you??™re protecting: Relying on an
electronic copy is dangerous enough.
