While some question the overall security of virtualizing servers and virtual server hosting, most of those questions focus on uncertainties around the process, especially in terms of data backup and system recovery. According to a recent report from InformationWeek, encapsulation could hold the key to successful data security on virtual servers.
When virtual servers are created, the many pieces of data are converted into one encapsulated image, making it possible to divide the device into multiple parts. When this is accomplished, a backup encapsulation is also created to retain that data in its original state.
According to the news source, encapsulation could revolutionize data backup if organizations can upgrade their recovery processes. Currently, companies follow the same restoration processes that were standard for traditional servers. If IT professionals can update the recovery of encapsulated data to provide users with direct access to encapsulated backup data, virtual server security could become more reliable.
Security concerns are especially prevalent in virtual server hosting environments, such as a VPS server. However, Desi Valli, COO and executive director of a web hosting company, told CIOL.com that hosted server environments can be more reliable than traditional data centers because the host is able to focus more resources on maintaining security.
