Access "Deduplication extends to archives"

Published: 20 Oct 2012

DATA DEDUPLICATION has become table stakes technology in many disk-based data protection products, including those from Avamar Technologies, Data Domain, Diligent Technologies and, most recently, Symantec with NetBackup PureDisk. Using the technology, these systems can squeeze orders of magnitude--between three times to 70 times--more data onto a system, depending on the vendor's implementation and your data. Now, Hewlett-Packard (HP) is putting deduplication into its archiving software. StorageWorks Reference Information Manager (RIM) for Files includes block single-instancing that provides three times to five times compression, says David Martin, HP's product marketing manager for data migration and archiving. RIM for Files reduces storage consumption, says Martin, and cuts network traffic. While deduplication on the client adds some latency, it's largely offset by reduced TCP/IP overhead. "It's like getting something for free," he says. --Alex Barrett Access >>>

    • Time to think outside the box when it comes to data protection

      Storage Bin: The concept of "That's the way we've always done it" isn't going to work anymore, and it sure won't help you build an efficient disaster recovery plan. It's time to think outside the box when it comes to data protection.

    • The rise of the ultra-dense array by Stephen Foskett

      Disk drives are getting smaller and smaller even as their capacities rise. Now storage vendors are packing more disks than ever into smaller spaces, which saves costly data center real estate. But the denser arrays also have a downside--higher power consumption and more heat.

    • A look at data classification products for e-discovery

      New technology products that look inside data can help you classify and manage that data more effectively. But these tools can also be leveraged for e-discovery, allowing specific data to be found and acted upon quickly to satisfy legal requirements.
