Let's be honest...
Whether you call it:
- Web Business Continuity Planning
- Contingency Planning
- Systems Assurance Plan
- Recovery Planning
They are all euphemisms for Disaster Recovery. If your business
would be seriouly affected by loss of your web presence (E-mail and Website), it would be prudent to
prepare a plan to provide these services in the event of an extended outage.
Certainly, the first thing that comes to mind in continuity planning is backing up the website. This is an
appropriate starting point, but it doesn't restore your business' internet presence, in and of itself.
Consider the types of failures (disasters) that could keep your business out of service for extended periods.
First, you might have a data corruption on the server (disk failure, database failure, administrative
error, sabotage, etc). Or worse, the server (or entire building that houses it) could be destroyed.
Lastly, portions of the Internet might be unreachable due to physical, hardware, and/or software
problem (common carrier failures, denial of service attacks by hackers, etc.)
For guaranteed continuity, we recommend that you provision a duplicate website and e-mail in another server, in another
part of the country, on another Common Carrier's network.

In the example at the left,
web services for YourDomain.com is provided by a server on the East Coast. Then in the
site shown as YourDomain.net (or something similar) serves as your backup site with everything redundant.
Your active site is
backed up to the mirror site
as often as required for your needs (usually daily, but could even be many times per day to capture database transaction data).
Then in the event of your server being unreachable, the system is configured to the
mode by directed the Internet Domain Name Service (DNS) to the mirrored server. In most configurations,
DNS is co-located with the webserver. We have separated it to a third location as additional protection.
While this change-over may take several hours to propagate the Internet, you may advise your
most critical customers that they may use the alternate domain in the interim.
