Keep your customers informed of the situation. Whether it's a blog, IM, or even phone calls keeping everyone in the loop build customer confidence. Not knowing is often the biggest problem. Honesty is the best policy. Covering up data disasters will lead to mistrust.

 
 

Check that data backup and recovery solutions are in place. For any business that own a server, it is a central part of the data recovery plan. What would happen to a small business if the server crashed the day before payroll? While this may not qualify as a major disaster, for a small-business owner unable to make payroll, this could lead to distraught employees. Having the server backed up allows the business to replicate the server applications and environment in the event of a disaster.

 
 

Keep track of your business processes. Make a data recovery plan. Consider how each is affected in the event of a disaster and make sure there is a data recovery plan for all mission critical systems. Don't assume that older systems are no longer being used.
