The memories of 9/11 and Hurricane Katrina are still fresh, but it seems that too many enterprises are still not taking the matter of disaster recovery seriously. Fortunately, a number of simple and low-cost methods can at least mitigate the impact of a devastating loss. In many cases, adequate preparation is a matter of common sense, such as maintaining a remote repository for drivers and other critical data. And there are a number of software tools designed to help in the planning.
On a more structural level, vendors are beefing up wide area services designed to restore remote data to whatever infrastructure, mobile of otherwise, might still be functioning. In Europe, ADVA recently demoed a 10G Fibre Channel WAN using dense wavelength division multiplex transmission over public optical networks. The best part is, not only does it come in handy in the event of a disaster, but it can also be put to good use as a grid network or for storage consolidation.
But these types of solutions are not reserved merely for the big players. Small businesses have a range of options as well. From switching to hosted software to turning to third-party remote storage solutions and other external facilities providers, even the most micro-businesses have the means of keeping the data flowing.
In fact, the greatest roadblock that enterprises of all stripes face on the way to effective disaster recovery is the belief that the network is immune to serious loss.
