EMC World 2009: Head to the source for de-duplication

The EMC Networker has been merged with Avamar technology to provide sourced-based de-duplication.

Source-based "de-dupe," as it has been called, differs from target de-duplication by happening on the client rather than once it has reached the back up device.

EMC claimed Networker is the only major-back up application to allow this. It also claimed it will reduce time taken to back up by 90 per cent and requires 98 per cent less storage.

EMC acquired Avamar back in November 2006 and thanks to this technology it can now provide services for Microsoft, Oracle and VMware systems.

It has also released the Networker Fast Start, which works on the same principles for medium sized enterprises.

EMC has extended its other back-up products too, releasing new software with its Disk Library 1500 and 3000 models claiming to increase replication throughput by up to 80 per cent, as well as extending the management capabilities within its Data Protection Advisor.

Acknowledging controlling costs and storage efficiency as two of the major problems for IT managers, Mark Sorenson, EMC's senior vice president of storage software, said at EMC World in Orlando: "There is no one size fits all when it comes to back up environments, which is why EMC offers such an extensive portfolio of solutions that can be mixed and matched - to provide the right recovery time and recovery point objectives."
