The data deduplication dilemma: Why SMEs need Dedupe -
Now that the hard drives of 2TB cost less than $ 100, why would anyone be worry about data deduplication? Why bother with a new system when you can throw records on the problem?
"Dedupe should be part of the modernization of data to boost productivity by reducing the data footprint, storage tiering, and revision backup process," said Greg Schulz, founder and Senior advisor to the StorageIO Group. "Get in the door with the slogan deduplication and treat other data storage and management issues."
the vendors define "dedupe" to adapt their products, so be prepared to hear dedupe described as the compression of specialized data and duplicate files are removed from the primary storage or backup data. deduplication technology can be applied to primary storage, secondary storage at the backup process, and storage after backup. optimizing files and compression, done by the hardware or the software, dedupe can be tagged.
Laura DuBois, program vice president, IDC Storage Software and Solutions, did a study in 2010 of the use of deduplication in mid-sized companies, which defines IDC as 100 to 999 employees. "We found about 43 percent use dedupe, and 31 percent are in the implementation process."
Mike Bollman, director of product marketing for Quantum DXi4500 deduplication backup appliance, said: "Our research shows that companies with a certain type of dedupe deployed, there are about a rate of 25 percent adoption in companies with fewer than 100 employees, more adoption in the 100 to 500 range, and more in the company.
Quantum Corp., backup solutions provider, recovery and archive, claims squeeze up to 20-to-1 space savings with deduplication and compression with the DXi4500, which comes in versions 2.2TB and 4.4TB. The company based in San Jose, California, uses a variable block approach that beats block fixed rates of 2 to 1 compression ring. But do many SMEs have 40 or 80 terabytes of data to be stored?
"Not that many small businesses are worried that a lot of data in a single backup," says Bollman. "But with our compression, you can perhaps keep the value of the 90-day data backup on your hard disk, including many restore points. Without dedupe, you can have the value of save points and rollback of only three or four days. "
The list price of the DXi4500 appliance, for hardware, software and licenses, starts $ 12,500. Other dedupe appliances for backup and data management can be found in the table, "sampling deduplication Appliances."
aN ELUSIVE KING
Cam Bulanda is vice president of storage, servers and virtualization to Insight Enterprises Inc., a reseller Quantum in Tempe, Ariz., with total revenues of $ 4.1 billion in 2009. "We are optimistic about the Quantum dedupe and equipment as a best practice for the management of data," he said. "the the device is much more than a piece of server backup hardware. "
as bullish as Bulanda is, however, deduplication still an educational process for many customers." It was difficult assign a tangible return on investment for dedupe, because customers could not quantify the costs of lost files, and to move the tapes around, "said Bulanda. "They figure it's easier to throw more storage at something to bring a new solution."
Despite the learning curve, Bulanda said there are ways to present dedupe to solve critical problems. "One of our clients had a data size of the problem," said Bulanda. "Their backups increased from 14 terabytes up to half a gigabyte. Another client, a national manufacturer, needed help to stay in their backup window to avoid an impact on production. Their backup was once eight to 12 hours. Now it's up to 30 to 90 minutes. "
While companies often mix the remote office backup data to larger offices, they found that although the disk space may be less expensive, bandwidth is not. Bulanda appreciate the approach of the Quantum device uses for such situations, since the devices are pre-configured and can be managed remotely, to ease the burden on IT remote offices.
"deduplication devices are still expensive, but given the right steps and situation, they will save customers money and protect their data," said Bulanda. "In five years, we believe dedupe will be part of all new storage and backup projects. "
