"We don't do recovery anymore, because what everybody wants is continuous operations," Berman said.
While there are probably industries that still take 6,000 tapes to a recovery center and restore all the data, he said, restoring thousands of severs comes fraught with mishaps. The CIO's worst nightmare is corrupted data. "When I'm talking to CIOs, it is all about how do we make sure the data has integrity," he said.
Continuous backup also removes the burden of disaster recovery testing, which many organizations give short shrift.
"Organizations swap from their primaries to their backups without even thinking. You can go over and make sure the backups are good five times a day, and organizations do that," Berman said. "We're not really trying to retrofit recovery into the operation; it is the operation."
Berman is not the only one making apocalyptic statements about DR. Server and storage virtualization -- done internally and provided externally in the cloud -- have fundamentally changed the kind of equipment and processes needed for recovery by companies and by disaster recovery outsourcing providers.
The use of cloud computing is effecting a "tectonic shift" in DR, said Sam Gross, vice president of global IT outsourcing solutions at Unisys Corp. Companies can now use cloud computing to conjure copies of their applications that can be brought to life at a moment's notice. And companies that are building new data centers, like Yahoo Inc. and Google Inc., are constructing them so that any data center can stand in for any other.
"The cloud allows you to plug in anyplace," Berman agreed, citing a recent demonstration of this in communications, where he watched a company eliminate the need for employees' desk phones by spoofing their cell phone numbers to look like calls were coming from the original source. "Technology is moving toward continuity. We are becoming far more time sensitive than we ever have before, and that has changed recovery."
Internet service provider Savvis Inc. espouses the same view. The company is building its cloud computing infrastructure for business continuity to be a DR substitute, "for pennies on the dollar," said David Shacochis, vice president, research and development.
Logistics: Distancing the technology from the business operations
Despite the fact that IT now has cloud computing and storage area networks and communications systems that can plug in anywhere, many companies still insist on putting the technology under the same roof as the business. But that, too, is beginning to change, Berman said.
A few years ago, he was consulting with a big financial institution that complained of frequent outages in critical servers. The company housed the data center with the business operations, "because the operations felt they had to touch the technology." It turned out that when members of the nightly cleaning crew mopped the floors, they were short circuiting the servers.
Berman said the notion of physically distancing the servers and data center technology from business operations is an offshoot of the British "triangulation" method that basically advocates taking the technology that runs one building's operations and putting it in a different building. "People are getting smarter about not putting everything at risk at the same time," Berman said.
Yahoo rethinks business continuity
Yahoo has spent the past four years reinventing its business continuity and disaster recovery strategy as it built new data centers. In its newest data centers, Yahoo is eliminating uninterruptible power supplies (UPS) and backup generators by ensuring that every data center can stand in for any other.
When the lights go out at Yahoo's new upstate New York center, another facility resumes the work, said Scott Noteboom, director of data center operations at Sunnyvale, Calif.-based Yahoo. The result is high-performance geographic replication of functions.
"The redundancy is now between markets in a country, not in the data center itself," said Noteboom, who was recruited by Yahoo from the colocation industry to head up the company's new data center strategy and talked about it at the recent EmTech conference (see sidebar).
Yahoo's motivation for eliminating the UPSes and generators was to cut the power losses that come with this gear. The move has reduced energy losses due to power transmission in the data center by half, from 38% to 19%. And that leaves some serious money to plow back into backup and replication between the data centers.
