Planning and Implementing Virtualization Disaster Recovery Plan

With the promulgation of cloud-based computing solutions, many small businesses are realizing the benefits of a virtualized disaster recovery plan. Business owners have always understood the necessity for data backups, but many still employ traditional methods. Onsite backups to network servers or other storage media are great solutions for small-scale disaster recovery, like a virus or hardware failure, but in the event of a large-scale disaster, an onsite backup will be destroyed, along with the primary data.

That's where a virtualized disaster recovery plan comes in. The features of such a plan can help businesses mitigate most of the damage from a disaster. A virtualized system incorporates backups, data replication and recovery into a single system, reducing costs and increasing redundancy. There are a few key elements a virtualized disaster recovery plan needs to function.

An Automated Backup Tool

The days of once-a-day backups are long gone. A good virtualized disaster recovery solution will employ a backup tool that constantly updates the backup media with changes as they happen. When disaster strikes, backups will contain data that is current up until the moment of the outage.

An Offsite Alternate Location

Also long gone are the astronomical expenses of having to create a completely separate network offsite to keep a copy of your critical data. Virtualization allows for your backups to be mirrored in alternate locations. Should your primary backup location suffer the very disaster it was designed to mitigate, your alternate offsite location contains an up-to-the-minute copy of your critical data. This form of replication is invaluable.

Reliable Network Connections

The weakest point in a true virtualized disaster recovery solution is a reliable network connection for all the elements involved. Your plan depends on having at least two networks, primary and main offsite backup, as well as additional networks in alternate locations, talking to each other constantly. The networks must have a reliable connection, operating at a speed suitable for real-time updates to storage media. Your service also needs to include sufficient bandwidth to allow for the constant transfer of data.

Once all of the physical resources are in place, you're ready to activate your virtualized disaster recovery system. The right software can turn this process into a series of simple clicks. Once your primary servers have been programmed with the location of the offsite servers, replication will begin. First-time replication will be a time consuming process. Additional real-time updates to offsite media will happen much faster, as only changed segments of data needs to be transferred to the offsite networks.
