As today's businesses invariably perceive corporate data as a strategic asset that need to be shielded against a gamut of risks and threats, data protection has posed to be a high-priority objective for IT organizations. In turn, IT organizations, of late, encounter the challenges of analyzing, installing, and efficiently managing their data backup and recovery infrastructure.

There is a revelation that organizations face challenge in justifying the costs associated with data protection solutions. Reason being, data protection is usually recognized not as a revenue-generating function but rather an inevitable business strategy - an exorbitant cost that most organizations would like to slash it substantially. However, the presence of natural and manmade disasters like earthquakes, lost backup tapes has increased the visibility and augmented the significance of data protection.

There is no denying the fact that IT companies don't set standard definition for "data protection" and its functionalities, but they believe that any comprehensive data protection strategy should cover the following areas:

Data Security: Blocking illegal access to data, which perhaps includes the application of technology such as encryption as well as application-based security technologies.

Data Availability: Make sure to keep your data available in order for making it compatible for business applications. This usually involves installation of high-availability storage solutions that use technologies that emphasize on preventing single points of abnormality in the data path and/or the storage targets.

Data Backup and Recovery: Make sure that a point-in-time copy of data can be reinstated in order for business operations to begin again.

It is noteworthy to mention that these functional areas are closely connected. For instance, a backup of a database is developed to cater data backup and recovery needs. However, it might be crucial for that backup copy to be encoded, especially if the backup exists in portable storage media (tape cartridge), which is eliminated from the protection of the data center and susceptible to unauthorized access.
