Any company that is large enough to have IT infrastructure needs the applications delivered from that infrastructure to be always available, even after a disaster. On-premises backup provides strong protection from the most common outages caused by device failure or human error. But local backup cannot help business recover from a disaster without offsite backup, and smaller organizations are less likely to have a second site where they can host IT infrastructure.
A practical and affordable solution deploys Drobo iSCSI SAN for on-premises backup and leverages AWS Storage Gateway to back up to Amazon S3 (Simple Storage Services). The simple addition of a VM into the existing infrastructure is all that is needed to connect to Amazon S3.
