Does the Public Cloud, like AWS, Deliver for Data Backup?

When it comes to bandwidth for data backup, cloud infrastructure is a defining measure. What cloud best fits the bill: purpose-built vs. public cloud?

There are many things to consider when evaluating the right cloud to complement your data backup solution. One of the most crucial is how the cloud handles bandwidth. And how it will handle not simply backup, but fast restores and business continuity. It’s important to look under the hood at the infrastructure of the cloud.

Cloud backup is unique in that most of the data transfer is over the span of about half dozen hours. For example, a US-based provider would likely receive the bulk of their jobs between 11pm Eastern Time and finish receiving them by 5am Pacific Time.

This differs from other non-backup applications, where much of the traffic is spread throughout the course of the business day. One exception is streaming services like video and music, which also both reach their peak in the evening and late evening hours.

Streaming services are often at their peak at the same time backup jobs are trying to complete, meaning that bandwidth utilization may have to be divided up among a wide variety of other processes in the generic cloud. With a purpose-built cloud, there are none of these concerns. A purpose-built cloud can focus all of its bandwidth on receiving backup jobs and sending recovery data.

Restores also use network bandwidth as they transfer data to the originating business. During the day these restores may have to compete with other business applications. Daytime is also when file sync and share processes are at their busiest; they synchronize data as it changes throughout the business day. In the generic cloud use case, restores will probably occur when all the other applications are at their busiest. This could make for a slow restore for a business that needs to keep their operations running.

Datto designed and manages its purpose-built cloud specifically for data backup, fast restores and to enable business continuity. There is no conflict of opposing data demands. In a purpose-built cloud, like Datto’s, no other unrelated tasks are running so managing recovery during the daytime should not be an issue.

Bandwidth allocation is just one of the key differences between a purpose-built cloud vs. a public cloud.
