It seems that executives of a whole herd of startups and  mainline storage suppliers have become fascinated by the intersection of cloud  storage services and disaster recovery. For example, my Inbox contained a  message from OnApp telling me that the company had  just announced "a new Disaster Recovery-as-a-Service (DRaaS) capability  for the its cloud platform used by public, private and hybrid cloud services  providers worldwide."
  Here's a snippet of the announcement:
  
    OnApp DRaaS adds real-time data replication and restore to  OnApp clouds. It enables services providers to offer Constant Data Protection  (CDP) for enterprise applications and data that demand the highest-possible  resilience, and expands the range of applications that businesses are willing  to host 'in the cloud.' OnApp DRaaS is now in beta testing with OnApp cloud  providers. General availability is planned for Q3 2015.
  
    OnApp DRaaS uses distributed cloud capacity over secure  connections to replicate virtual server data in real time.
The key to this announcement is that OnApp would like  services providers to rely on its OnApp Storage, which is in turn built upon its  OnApp Cloud platform.
Better Than Sliced Bread?
  Everyone in the storage, backup and recovery, and systems  business seems to believe that their DRaaS offering is the best thing since  pockets, and far better than sliced bread or canned beer. Over the last few  months, I've heard similar stories from Cisco, EMC, NetApp, and a whole host of  backup and disaster recovery (DR) software companies.
DR is a set of processes, procedures, backup or  replication software, and storage designed to survive the loss of applications,  systems, databases, and so on. The  assumption is that things are going to fail; and maintaining copies of  important data, usually off-site, can make recovering from that disaster both  easier and quicker.
  
Cloud storage suppliers added on the concept that the  storage that's the target of both the backup and recovery technology should be  both off-site and in their data center. They, of course, would like enterprises to rent storage space on an  as-needed basis, which they say will save money over the company purchasing its  own storage infrastructure.
Dan's Take: The Consultant's Answer
Depending on the size and capabilities of the  enterprise, this just might be a good deal. 
Smaller enterprises would like to enjoy the comfort of  knowing that their critical data will survive the loss of their application  systems without them also having to accept the burden of acquiring and  maintaining the storage, the SAN, the systems, the backup and recovery  software, and, of course, the costs of staff, facilities management, power and  cooling.
Departments of larger enterprises might prefer to move the  cost of these things from the capital to the operational expense side of their  ledger by subscribing to a services offering rather than purchasing hardware,  software licenses, and having a sizable staff devoted to backup and recovery.
  In the end, the decision hinges on whether an ongoing  services offering makes better business sense than acquiring the IT resources  needed.
