Why has cloud-based DR changed the game?

Cloud-Based Disaster Recovery as a Service

A lot has changed in the disaster recovery (DR) space in a relatively short timespan. Thanks to emerging technologies, DR has evolved from a plan focused on cleaning up after a disaster to a plan that focuses on getting your core applications back up and running at full capacity in the shortest amount of time you can afford.

A lot of those changes come from advances in Recovery-as-a-Service (RaaS) technologies. Compared to Backup-as-a-Service, RaaS offers a more holistic, complete protection plan. Compared to traditional colo, subscription, warm- and cold-site DR plans, RaaS offers a more affordable option with better RTO and RPOs.

Aside from besting traditional cost and recovery points, why else has cloud-based DR changed the game?

Cloud-based RaaS enables complete recovery of your entire application for a smooth recovery after declaration. But, choosing cloud-based DR with a multi-tenant public cloud provider also provides the backing of a success team dedicated to helping your team create an ideal runbook and execute that runbook in the event of a declaration. It means 360 degrees of support for success, regardless of what happens.

A common misconception is that backups and backups-as-a-service offer your business the same results as recovery-as-a-service.

In reality, backups protect the data, not the applications. Should your business be hit with a disaster, your team will be left with the “puzzle pieces” to put back together when the backups are used as a recovery solution. Alternatively, with RaaS, the environment stands back up in a designated RTO window, from the agreed upon RPO, without your team having to put the puzzle back together.

RaaS leverages consistency groups for complete application recovery. Rather than replicating the pieces and data points, groups of VMs are “locked” together prior to replication. Because of these consistency groups, all locked VMs are recovered from the same point in time. All resources come back in sync and no transactions are lost. You recover the puzzle as a whole, not in pieces that need to be reassembled.

The supporting VMs can be located across disparate hosts and storage arrays, even different processor chip sets, but because the replication groups together VMs regardless of physical location, it consistently replicates the VMs using a group-level policy.

That’s less time for your business to be down and puts your entire company back to work quicker. The differential in time gained between backups as your recovery solution and a RaaS can more than pay for itself in the amount of business you can complete during the timeframe differential.
