The Top 4 Approaches to Cloud Disaster Recovery

Top 4 Approaches to Cloud Disaster RecoveryWhen coming up with a disaster recovery plan, the cloud can be a useful option. Choosing the cloud decreases the need for on-premise data centers, as well as IT infrastructure and resources. As a result of this, costs are lowered, but cost reduction doesn’t alleviate the potential security concerns that come with the cloud. To help you choose which cloud solution is right for you, we’ve outlined the different approaches to cloud disaster recovery.

Managed Applications and Managed Disaster Recovery

A company can place primary production and disaster recovery instances into the cloud to be taken care of by a managed service provider (MSP). Using this method, you gain the benefits of the cloud, while deferring the responsibility of disaster recovery to your service provider manager. However, when going with this approach, you must be confident in your service provider’s ability to deliver continuous service. Negotiating a suitable service-level agreement is what will allow you to determine the terms of disaster recovery services.

Backup to and Restore From the Cloud

With this method, data and applications stay on-premises, and data is backed up onto the cloud. In the event of a disaster, the data on the cloud will be restored onto on-premises hardware. In effect, the cloud backup acts as a tape-based off-site backup. Products that move data into the cloud offer features such as compressing and encrypting data before transferring it to the cloud. Recovery is a challenge with this approach, especially when dealing with terabytes of data that have to be restored on-premises within a defined RTO.

Backup to and Restore to the Cloud

When using this method, data is restored to virtual machines in the cloud, rather than to on-premises infrastructure. By restoring to the cloud, restoration can occur when a disaster happens, or on a continuous basis. To maintain continuous restoration, disaster recovery virtual machines must be kept up to date. This maintenance also helps to meet determined RTOs. As part of their disaster recovery offering, some cloud service providers assist in bringing up cloud virtual machines. On the matter, Chris Poelker, VP of enterprise solutions at FalconStor Software stated, “several cloud service providers use our products for secure deduped replication and to bring servers up virtually in the cloud.”

Replication to Virtual Machines in the Cloud

If your business deals with applications that need aggressive RTOs and RPOs, this approach will be a good option for you. Replicating data to cloud virtual machines allows for the protection of cloud and on-premises production instances. Essentially, replication works for both cloud virtual machine-to-cloud virtual machine and on-premises-to-cloud virtual machine data protection.

Cloud disaster recovery could be a great option for your business as a way to reduce costs and infrastructure, as long as you choose the approach that is right for you.
