Small to midsized businesses (SMBs) once viewed business continuity (BC) planning as an expensive luxury. However, upgrading disaster recovery capabilities is a major priority for 56% of IT decision makers in the U.S. and Europe, according to Forrester Research Inc.'s 2007 Market Overview: Business Continuity Planning.
Unforeseen events are increasingly driving adoption. Manhattan-based Cambridge Security Services Corp. implemented a set of recovery protocols following two major disruptions: the Sept. 11, 2001 terrorist attacks and a major power outage in 2003. Since then, the 707-employee security firm has spent $110,000 to upgrade equipment and build redundant capabilities.
"We provide essential services to our clients when they need us the most," says Ralph Martell, the company's regional vice president. "As we grew, we realized we weren't prepared to deal with a national emergency."

Conducting a business impact analysis (BIA) is often viewed as an exercise that is exclusive to enterprise-class organizations with seemingly limitless funds for consulting services. Large consulting firms often spend months mapping every business process and interviewing numerous business unit representatives to come up with sophisticated financial loss projection charts.
SMBs have the same requirements as enterprises, albeit on a smaller scale.

Establishing the recovery time objective (RTO) for your critical data is imperative. The RTO is the specific amount of time before your business is negatively impacted by the interruption of a system or application supporting one or many critical business processes. It is generally accepted that an outage exceeding the RTO set by a company can be considered a disaster.
It is important to note that an RTO is not the same as a service-level agreement (SLA). SLAs are usually defined for a single application or service and can be much more aggressive than an RTO, as they typically include planned outages and often assume the availability of other IT infrastructure components. Additionally, the consequences of a missed SLA are often not as severe as a missed RTO.

Disk imaging can provide working backups with fast recovery to handle the most common kinds of storage problems, such as accidentally deleted files. Disk imaging software typically takes images of changed files at frequent intervals and can recover files and folders quickly.
Disk imaging software can also be used to create an image of an entire disk or array for disaster recovery purposes. Often disk imaging software will export the image over a network to a tape library or remote location for additional protection. While you probably have working backup imaging capability in your existing software, don't automatically assume it will do a good job for disaster recovery. It is worth taking a look at the feature set in what you have and perhaps purchasing a program (or subscribing to a service) for disaster recovery.

SMBs often rely on their IT staffs' knowledge of the environment and feel they are covered in the event of a disaster. But what if the staff is unavailable following a disaster and the company might have to rely on other people that are not as familiar with their IT environment to assist with the recovery effort. This is where all the shortcomings of the disaster recovery plan can be exposed and why it is imperative to test before this happens.
Because of its ease of deployment and integration, server virtualization can be a highly effective tool for disaster recovery for SMBs. Server virtualization addresses three concerns related to disaster recovery:
