Nevertheless, will the benefit of this kind of compression be enough to overcome users' reluctance to tamper with online data? That may depend on the market sector, suggested Forrester analyst Andrew Reichman.
"There is considerable market resistance to de-duplication of primary data, where the industry has long relied on creation of multiple copies to guarantee the protection and availability of critical data," he explained.
"If you are in the banking or financial services sector, don't expect your peers to adopt this any time soon. But, if your firm has less stringent SLAs around data loss and availability and faces staggering growth from day-to-day operations, this could be the missing link that allows you to stay ahead."
Carter George agreed, saying the technique is best suited to relatively static content such as online photos, social networking sites, oil and gas exploration data, and so on.
It certainly works for photo sharing, said PhotoWays CTO Graham Hobson. His company gets 1.5 million photos uploaded per day and is one of around a dozen early customers for the Ocarina technology.
"The first time I heard about Ocarina, it sounded simply too good to be true," he admitted, adding though that, "Based on our initial testing, we are confident that the Ocarina solution will allow us to defer a significant portion of our storage purchases this year."
He continued: "Bottom line, we believe that Ocarina will pay for itself within six months of installation, save us millions of euro over the next few years, and change the way we buy storage and the overall economics of our business in the future."
