Cloud backup was originally conceived as baseline protection against business data loss

Choosing the Right Data-Protection Solution for Your Business
The concept of cloud backup has been around awhile and seems well understood: For a monthly fee, a third-party vendor will back up your business data and store it “in the cloud” (network of servers) so it can be retrieved on demand at a later date.
What is less well understood is the idea of cloud disaster recovery. Its name gives some indication of its purpose, suggesting a more robust response to an unforeseen data-loss emergency. But is a more robust response always the appropriate response? In other words, how does one calibrate a solution to best fit one’s specific needs?
Traditional Cloud Backup
Recovery time via cloud backup depends on several factors:
In the case of retrieving a single file, data recovery might take minutes, or, in the case of having to restore an entire server image, it may take anywhere from hours to weeks, depending on the above factors.
Cloud Disaster Recovery
The cloud DRaaS protection process is similar to the cloud backup process: Data (individual files or entire server images) is backed up over the internet and stored in an off-site data vault. The difference lies in the ability of DRaaS providers to failover live servers to an alternative cloud environment, giving a business newfound capacity to run live production servers in a virtual environment.
Enabling users to connect to an alternative data center running live servers decreases recovery time to a matter of minutes and hours from the previously attainable days and weeks.
Why It Matters
As you can see, cloud DR is more labor-intensive than a simple cloud backup solution, which does not require having to spin up a live IT production environment. Your choice of which level of protection to adopt should therefore be based solely on your company’s Recovery Time Objective (RTO), which is the length of system downtime that your business can tolerate in a crisis.
If your RTO is flexible (greater than 24 hours) then we recommend using a cloud backup solution. If your RTO is tight (less than 24 hours), a cloud disaster recovery solution is your best option.
