It's easier and less expensive to protect virtual server data but, according to a recent survey, most companies don't back up all of their virtual servers.|
Virtualized servers are being deployed in data centers at an increasing rate. Benefits such as cost savings through consolidation, simplified administration and lower energy consumption are some of the primary reasons for the proliferation of virtualized infrastructures. On the flip side, the ease of deploying virtualized servers bears the risk of spawning new servers running critical apps without the necessary attention to data protection and disaster recovery (DR). Moreover, data protection and DR in virtual environments pose a variety of challenges, and processes deployed for the physical infrastructure may not work (or work differently) for virtualized servers.
According to Symantec Corp.'s annual Symantec Disaster Recovery Research Report, 35% of virtual servers aren't covered in organizations' DR plans; in addition, only 37% of those surveyed back up all of their virtual systems. The primary reason cited for insufficient data protection and disaster recovery of virtualized servers is a lack of resources. IT departments that are already stretched to their limits don't have the time to put in place workable DR plans for
| many of their virtualized systems. And the tools for protecting physical and virtual servers differ in many cases, resulting in higher training, labor and software costs. Notwithstanding the challenges identified in the Symantec survey, protecting virtual server data is simpler and more cost effective than doing the same for physical servers.
