For businesses employing virtual servers, whether they be virtual private server hosting organizations or major companies with an on-premise data center, data backup designed specifically for virtual environments has become critical, InformationWeek reports.
According to the report, virtual machines are not, at first glance, all that different than other systems currently in use. After all, they are just disk files combined with a configuration system, the report said. However, virtual machines tend to hold large chunks of data, making it logistically unrealistic to have an exact copy of all server images.
Typically, companies deal with this logistical challenge by using snapshots of the server. These quick images backup the server prior to making any changes, and are deleted at the first safe opportunity, the report said. While this system can be effective, organizations should develop better, virtualization-specific ways to make data redundant because snapshots can be difficult to manage and maintain.
According to a recent Hub Pages report, businesses using a VPS hosting solution should seriously consider using an off-site backup system to help ensure reliability. While most hosting providers can reliably backup customer data, technical malfunctions or security breaches can corrupt a backup image, making a remote solution more reliable, the report said.
