By 2010, the amount of data added annually to computer systems worldwide will swell to 988 exabytes, according to an 2007 EMC-sponsored report from IDC. A 2008 update on the report found that in 2007, the digital universe measured 281 billion gigabytes -- 281 exabytes -- an increase 10 percent greater than analysts had predicted a year earlier. While roughly 70 percent of the data generated in the digital universe is created by individuals, enterprises are responsible for the security, privacy, reliability and compliance of 85 percent of it.
This corresponds almost exactly with what we're seeing in the market. The old adage "nobody ever got fired for buying (three letter company)" doesn't hold true anymore. The first storage budget item that got cut at big business was the next quarterly purchase of $30/GB high-end SAN, but new data still needs a place to go because the rate at which it is being generated isn't slowing!
At Permabit we've seen a huge surge in interest in areas like financial services, where money used to be almost free. Through a commodity hardware architecture and advanced software in our Permabit Enterprise Archive, we can store their critical long-term data with reliability far better than their high-end SANs, at a cost less than offloading it to tape.
One area I'd like to comment on is deduplication. At the backup level dedupe can see savings of up to 50x or more, but that's generally based on doing it wrong -- backing up the same thing time after time. Right now data is being written to primary storage at $30 to $50/GB, and then backed up at an aggregate total cost of maybe $5 to $10/GB more. Deduplicating VTL or backup can shave a few dollars off this, at best.
Instead, much of that data can be moved to an archive tier at $3 to $5/GB, and with an effective cost even lower with deduplication. Effective replication can eliminate the need for backup entirely. This path saves much more money, though isn't as seamless as merely optimizing backup. With economic pressures, any business would be remiss not to look at deploying an effective archive tier.
