The report does warn that online backup is not the same as disaster recovery. "Itï¿¼s important to understand that some services donï¿¼t provide complete DR but only data recovery. This is true of many storage-as-a-service and backup-as-a-service offerings. They back up data to their site, but they donï¿¼t have a backup of your system images or the ability to host you at their site." The report cites SunGard and Venyu as providers that are building out SMB-oriented backup services that can be the foundations for full disaster recovery systems.
The most familiar online backup options are "agent-based," meaning you download software to the machines to be backed up, and that software manages the uploading of data to the cloud. The problem here is that restoration of any significant amount of lost data requires waiting for the provider to send it on a disk, meaning your business won't be full recovered for at least a day.
Appliance-based services, by contrast, combine a local storage device which is then backed up to the cloud. That way, if your primary storage fails, you can restore quickly from the local device, but you also gain the benefits of offsite backup. bMighty's new, free Business Case Builder for business continuity devices can help you decide if that approach is best for your operation.
