We’ve seen big announcements recently about unlimited cloud storage offerings for a flat monthly or fee. Dropbox offers it for subscribers to its Business plan. Similarly, Google has unlimited storage for Google Apps for Business customers. In both cases, though, you have to be part of a business group of some sort. Then Microsoft unlimited storage for any subscriber of all Office 365 customers (Home, School, and soon Business) as bundled offering of OneDrive with the Office suite of products. Now comes word today from Amazon of unlimited storage to consumers…no need to be part of a business grouping or have bundled software come with it.
Today a colleague asked why all of this cloud storage couldn’t be used as file storage for the Islandora hosting service that is offered by LYRASIS. On the surface, it would seem to be a perfect backup strategy — particularly if you subscribed to multiple of these services and ran audits between them to make sure that they were truly in sync. Alas, the terms of service prevent you from doing something like that. Here is an excerpt from Amazon:
It did get me wondering, though. Decades ago the technology community created RAID storage: Redundant Array of Inexpensive Disks. The concept is that if you copy your data across many different disks, you can survive the failure of one of those disks and rebuild the information from the remaining drives. We also have virtual storage systems like iRODS and distributed file systems like Google File System and Apache Hadoop Distributed File System. I wonder what it would take to layer these concepts together to have a cloud-independent, cloud-redundant storage array for personal backups. Sort of like a poor-man’s RAID over Dropbox/Amazon/Microsoft/Google. Something that would take care of the file verifications, the rebuilding from redundant copies, and the caching of content between services. Even if we couldn’t use it for our library services, it would be a darn good way to ensure the survivability of our cloud-stored files against the failure of a storage provider’s business model.
