Well for beginners, “de-duplication” simply means NOT storing multiple copies of data. Say you have excel sheet and you mail it to your colleagues. You would have 10 copies of the same data. The story does’nt end here, your file server is backed up everyday as is your mail server. So you backup 11 copies of the excel sheet.

De-duplication means storing as many few copies as possible.

While some companies have solutions to de-duplicate data as it is backed up and some companies have solutions to de-duplicate data after it has been backed up. And now we await something that helps us de-duplicate data at the source itself.  Not that such technology is not available, but the fact that we have’nt actualy deployed and acted on it. Today my Veritas command central reports duplicate files across my storage  boxes, if I were to spend de-duplicating them, you would imagine whether I would I have time to spend with my family. I could think of the FAN {File Area Network} from Brocade, the tapestry solution, also some kind of de-duplication technology.

To summarize, I would support de-duplication at source, simply because I’m saving more resources. De-duplication on target would be easy to manage and faster solution.

Hackers briefly overwhelmed at least three of the 13 computers that help manage global computer traffic Tuesday in one of the most significant attacks against the Internet since 2002.

Experts said the unusually powerful attacks lasted as long as 12 hours but passed largely unnoticed by most computer users, a testament to the resiliency of the Internet. Behind the scenes, computer scientists worldwide raced to cope with enormous volumes of data that threatened to saturate some of the Internet’s most vital pipelines.

The motive for the attacks was unclear, said Duane Wessels, a researcher at the Cooperative Association for Internet Data Analysis at the San Diego Supercomputing Center. “Maybe to show off or just be disruptive; it doesn’t seem to be extortion or anything like that,” Wessels said. (more…)
