Before the Christchurch earthquakes a lot of businesses took the attitude of "It won’t happen to me”. Business continuity was a tick box exercise. Since the earthquakes we are now seeing more businesses taking action to improve their backup and disaster recovery plans.
Much like insurance, the question underpinning backup and disaster recovering planning has changed from "Can I afford to have it?” to "Can I afford not to?”. People have also realised that if you can’t rely on disaster recovery being there when you need it, then it isn’t really worth having.
The two most significant changes we are now seeing is a greater appreciation of the physical location of the protected data, and a move from manual to automated recovery processes.
Data storage: more than one site and city In terms of the physical storage of data, I think everybody has heard at least one IT horror story from the earthquake where backup tapes were stored conveniently on top of the server. Or how someone had routinely inserted tapes into servers but never checked that the data had been successfully written to them.
It is important to ensure data is routinely and successfully stored offsite and that the data is usable.
We are also finding that more businesses are looking for a second geographical location to store or back-up their data, ensuring their systems are replicated at a data centre situated in another town or city.
Automating recovery: when people aren’t available to help
With automation, the question we ask people is "What does your recovery plan look like when your key people are affected by the disaster?”
These people may be too busy dealing with the essentials of life to be focussing on your business.
It is also important your provider works with you to build a solution that focuses not only on securing your data, but that also considers how you will reconnect with that data after a significant incident. It’s not likely to be from the office or from a corporate device.
Relying on service providers or integrators for manual services isn’t really any better than the DIY approach as most service providers will be inundated with demands on their time post-disaster.
This is a key reason we have invested in networks traffic management products and in creating services that enable automated failover between our data centres.
Questions to ask your provider
Business needs and budgets vary greatly. When choosing a backup or disaster recovery service, there is more to consider than price.
Investigate the varying levels of management attached to the service.
