More and more companies are seeing the benefits of virtualization. They are being told by other companies and the IT world about the glory of the VPS mechanic and how it can help them save time and money on storage costs and server use and how multiple instances of an application or O/S can be run off of a single, virtual machine. But while all of these advantages can exist for a well-managed VPS network, a virtualized environment also offers another benefit – better backups.
Companies will often find themselves in the position of needing to test their disaster recovery but run out of time to do so. Such a test can consume days or weeks of time, backup tapes and planning, only to fail if something does not go as planned. Businesses can end up, backup tapes in hand, but with no real way to get up and running again. Disasters are by their nature unexpected and random – they will not follow established patterns or act according to plan, and this makes preparation for them at a physical level difficult.
VPS options are naturally backup friendly thanks to a number of features of the technology. First, virtualized environments are naturally “bare-metal,” allowing for real-time backups of systems and changing options according to the needs of the moment. In addition, virtual servers allow for a better ability to take snap shots and replicate data than traditional server options, providing what a system needs the most during a disaster – flexibility. In many cases, it is the down time after a disaster, even with a full backup on-hand, that destroys a company. VPS options help minimize this downtime and decrease the amount of time a company spends waiting for a system to restore.
