Over the next few days in San Francisco, thousands of hardware developers will be attending the Intel Developer Forum, which is being held at Moscone Center West. If you’re a hardware geek and you want to check out where (at least in Intel’s view) your favourite hardware platforms are heading, then

The purpose of this shootout was to analyze already backed up images of VM guests sitting idle on disk. We like to keep 7 days online, so I was curious as to how the two compared in our environment. Compressed vs Deduplicated COMPRESSED: (backed up via vRanger Pro over VCB, size on win NTFS volume)

Sepaton promises 40:1 dedupe, or your next disk’s on them July 30th, 2008 by Dave Raffo Just about all data deduplication vendors make claims about the dedupe ratios their systems provide, with the caveat that the ratios vary by data type and backup frequency. Sepaton today says it’s willing to guarantee its ratio for Exchange.

I’ve been doing a little testing with NetApp Deduplication lately but only in a limited test environment.  I know one thing for certain, deduplication and compression do not mix at all!  When you start to look at this technology make sure you’re dealing with uncompressed data.  This posting is more

All views my own, not of employer, mileage may vary, first born may be sacrificed, value of investments may go very down and not just down) When it comes to virtualizing your servers and workstations you are going to spend quite a bit more money on the SAN instead of a bunch of local disks.

By Jim Hankins If you remember back in my HP Deduplication - Part 1 post when we announced our new deduplication products back in June, I said that the deduplication ratio you can expect from a product can vary based on a number of factors.

I wanted to share a response I made on an EMC blog called, "The Backup Blog." We will also be sharing a response for our VLS product as well. There was too much to respond to in one post! Stay tuned!

Data Domain, Avamar and ExaGrid all report strong sales growth                               Byte and Switch profiled three separate data deduplication vendors: Data Domain, Avamar and ExaGrid. Each is having a great quarter, with sales up significantly.  Dedupe is still young, but it’s accelerating fast into mainstream enterprise traffic.

The enterprise data center continues to evolve, driven by ever-growing amounts of data and new demands for data availability - local and remote. These demands are driving companies to identify alternatives to existing data protection methods with deduplicating disk-based storage systems, such as Quantum's DXi Series, becoming a preferred backup target.

Whew... big title, hopefully the rest of the post will be a little lighter on the polysyllabic words. Ooops... Well, what's a day without a little irony? On to the subject at hand: as we have discussed in the past, there are two times at which deduplication can happen: in-line, and out-of-band.
