Amazon has simply launched a brand new knowledge backup service for enterprise referred to as Glacier. In comparison with AWS and different company archive options, Glacier is priced a lot decrease. The catch is that Glacier is designed for long run storage that gained’t have to be accessed fairly often, very like the previous photograph albums my mother insists I come over to take a look at.
At present, most companies use tape backup for archiving giant quantities of knowledge. Nevertheless, tape backup normally requires an costly upfront value that makes it unattractive to small and medium dimension companies. And since the service isn’t dynamic, it could pressure firms to buy bigger quantities of space for storing than you really have to be positive you by no means run out.
Glacier works in another way. As a substitute of utilizing tape, Glacier depends on giant networks of storage arrays made up of cheap high-storage disks. After which there’s the value, which is inordinately cheaper than comparable companies. Amazon is charging $0.01 per GB / month for storage on a pay-as-you-go system, and it’s free to switch knowledge in. Taking knowledge again out, nonetheless, is the tough half.
As a result of Glacier is designed for long-term storage, Amazon doesn’t count on enterprises to retrieve knowledge fairly often. It’s offering 5% of knowledge monthly accessible at no cost, and after that the value is tiered primarily based on the quantity accessed. There’s additionally an early termination payment if knowledge is deleted inside three months of importing it. Uploaded knowledge can take a number of hours to acquire as soon as the retrieval request has been made by means of REST API, so that’s one other factor to think about. There is no such thing as a payment for transferring knowledge between Amazon EC2 and Glacier in the identical area.
For these frightened about outages, Amazon ensures a 99.999999999% sturdiness ranking by redundantly storing knowledge in a number of server farms throughout a number of units. Amazon refers back to the group construction of knowledge as particular person “vaults”. That’s an amazing time period as a result of all knowledge uploaded is encrypted with AES-256 safety.
Again in 2007 IBM Technical Technique Director and researcher, Dave Russel, predicted that restoration options would transfer to the cloud. If Amazon has something to say about it, he wasn’t far off on his prediction.
