However, many people believe that disaster recovery requires expensive physical equipment, but that isn’t necessarily the case. In fact, disaster recovery and virtualization – using one physical machine that acts as several, independent ones – can be just as secure, but by using fewer machines, also more cost effective. Here are four important ways that virtualization and disaster recovery go hand in hand:
- Leverage: Implementing virtualization as part of your disaster recovery plan means that you can leverage secondary machines as virtual servers in failover situations. Many virtual machines on one physical server means that you save on costs and make efficient use of the machines you do have, particularly useful in a cloud computing environment. Maintaining fewer physical machines means that your IT department can focus on other forward-looking projects.
- Flexibility: Virtualization means that you can implement disaster recovery solutions that are not necessarily identical – you can customize your contingencies based mainly on need and not just on the equipment that is available. This flexibility also helps reduce unexpected downtime and promote business continuity as the best failover mechanisms have been applied to each area independent of other areas.
- Simplicity: Joining disaster recovery and virtualization together also allows for simplicity in your disaster recovery plans; each procedure can be tailored to the type of software, data, and usage in question. Instead of applying a one-size-must-fit-all solution, you can update each plan only when needed without affecting any other plan.
- Quick data recovery: When you do need to follow your disaster recovery plan, virtualization can make data recovery easier than it would be with physical machines. For example, your IT department can retrieve a copy of the files to be recovered, restore them to a new host – which could also be another virtual machine - and import the virtual machine configuration. Even in critical situations, the ability to maintain business continuity is strong.
No two businesses are the same and as such, no two disaster recovery plans are the same either. Implementing virtualization in your disaster recovery plans makes sure that you get reliability, security, and efficiency – and affordably too. If you need more information about how to incorporate virtualization into your business, contact any local and trustworthy IT company that specializes in virtualization.
