Our on-premise system, which we have developed, integrated and is currently in operation, collects a large quantity of data. The data is organized in several tiers, where the most recent data is accessed frequently, while older data is accessed very sporadically. To be compliant with business and disaster recovery requirements, we cannot keep this data just on one site because in case of disaster recovery, an instance of the system needs to be available at another site. Instead of developing our own solution, we use AWS Storage Volume Gateway in stored mode. It provides the necessary glue between the on-premise infrastructure on which the system runs, and the cloud storage where data is asynchronously synchronized to.

We've had no trouble at all. We were able to deploy a cloud backup solution with no impact to our users at all.
