Using the Cloud to Transform Disaster Recovery

The cloud as a platform is best suited for Disaster Recovery. This is because somebody else has the infrastructure, somebody else has the server infrastructure – All you really need to figure out in your business case is: How much money do you have to spend, and how quickly do you need to be up, and that is going to determine how you are going to look at it.

When we think about this from days, hours, minutes, seconds, it all depends on the kind of backup we are trying to get. Backup from tape takes days. Backup from disk can take anywhere from hours-to-days depending on how much data there is to do. Asynchronous replication take minutes. Synchronous replication takes seconds.


But there’s a gap between backup from disk and Asynchronous replication, that is how do we get from hours-to-minutes, days-to-minutes and that is where the Cloud Disaster Recovery actually comes into play. You can backup to the cloud, you can Restore to the cloud, you can run from the cloud and you can put it all back in your datacenter when you are unable to recover – that’s an extraordinary way to look at Cloud Disaster Recovery.

Cloud Based Disaster Recovery

Disaster recovery in the cloud – you can do in a few ways. You can do it yourself using the public cloud to architect a custom solution leveraging the agility and speed of the cloud. But if you are managing it all yourself, this means all the licensing and the equipment – everything, you have to manage it yourself. You are using a public cloud to do it, so clearly you’re leasing the infrastructure at some point.

Cloud-to-cloud – so this the ability to failover services from one cloud datacenter to another cloud datacenter. Clearly it would mostly be virtualized and someone else is managing the infrastructure so it is actually less burden on you and probably less cost.


Disaster Recovery as a Service – pre-packaged solutions that provide failover to a cloud environment. Which means you are running your datacenter, they are running their datacenter, you’re able to exchange information continuously, and what time to failover. That’s exactly what you do, you failover. That is in real time and depending on how much you want to pay for this and what type of recovery objective you want. You can do this in seconds and minutes, so very interesting.
