Re: [Networker] Networker and Data Domain

Hi Conrad and list:

We investigated Data Domain, and we did a test of a DD200 when it firstcame out, 3 or so years back. Was very impressed with the speed andsomewhat impressed with the dedupe ratio. However, it was way toexpensive for our UC budget.More to my point: we are interested in investigating Avamar, which isintegrated into Networker 7.4.2. It has in interesting implementationwhere the data duplication is discovered on the client side, such thatthe Avamar server keeps a hash of stored checksums, and the clientqueries the server as to whether the data block already exists on theserver. If not, the data is sent with the checksum, if so, only thenext checksum needs to be sent. This has the benefit of potentiallydramatically reducing network traffic.

I'm wondering if anyone on the list has experience with EMC Avamar? Itwould be great to hear some non-biased reviews before I proceed.


Thanks,

Jon

Hi, Kevin,

Leaving aside for at least a moment the discussion of vendors and spam,
I'm very interested in what you receive from your query about Data
Domain and possibly other dedupe vendors. I suspect other list members
will be as well. When you're done with your investigation, I wonder if
you could you please post a summary of your findings to the list?

One finding I'm particularly interested in: is it properly spelled
"dedupe" or "dedup"? :^)

Thanks!

Subject: Networker and Data Domain

If there is anyone out there who is using a Data Domain dedupe solution
with Networker and would be willing to have a conversation (good or bad)

about it with me, I would be appreciative.

We are looking at dedupe solutions and I am not endorsing any at this
point, but that is one that we have come across.

You can send me a private e-mail so as not to clog up the listserv.

Thanks,
Kevin
