In a world where businesses face an explosion in the volume of both structured and unstructured data, deduplication becomes a key technology in ensuring information is efficiently stored and protected.
This is according to David Scott, senior VP for HP Storage, who was speaking during the HP Discover conference, in Vienna.
Data deduplication is often called 'intelligent compression', or 'single-instance storage', and
can reduce storage needs by eliminating redundant data.
According to Scott, only one unique instance of the data is actually retained on storage media, such as disk or tape. Redundant data is replaced with a pointer to the unique data copy.
He pointed out that besides shrinking physical storage requirements, deduplication also makes disk backup faster and economically feasible.
Scott noted that initial deduplication methods left severe gaps for organisations. “These methods were made up of incompatible silos that included training, administration and data mobility,” he pointed out.
The other shortcomings, he explained, included restricted scalability and sluggish backup, which resulted in slow service level agreements (SLAs).
Scott also revealed the availability of HP's first large-scale deduplication appliance. He noted that the solution, the HP B6200 StoreOnce Backup System, processes and restores data at 28 terabytes per hour.
He pointed out that the new offering backs up data more than three times faster than competing systems, adding that the StoreOnce Backup System overcomes legacy dual-controller limitations.
Comparing the HP B6200 StoreOnce Backup System to EMC's DD890, Scott pointed out that the HP solution, at 768 terabytes, offers double the total capacity of its competitor.
He also revealed that accommodating exponential data growth is a key factor in reducing time and risks related to data backup.
