Or should I say, ‘Setting the Record Straight on Backing Up Optimized Data’? Carter discusses on this blog they myriad of ways to perform backups on optimized data. (His blog actually reads more like a white paper explaining how backup needs to be configured to work with his product.) One of the ways Carter describes to do backup is via NDMP and says “… is the most complicated.” The funny thing is that this is… Read more »

This video doesn't talk about the merits of one versus the other but how when compression (or capacity optimization is done right) it should enhance data deduplication, not impact it.  Enjoy and for more videos like this one go to the StorwizeChannel. classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="580" height="360" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0"

Users and Vendors alike have always had skepticism around capacity optimization and different points throughout history. The key, for end users is to be able to answer the questions:

What are you doing to my data? - This is directly related to availability and data integrity. If you can't ensure the customer will always have access to their data and it will be 'their' data then there is an issue.Whatever you do to my data… Read more »

How many of you have heard that compression and deduplication just don’t belong together? Like oil and water. I know from experience, when I worked for EMC, the Avamar sales reps and the Data Domain sales reps would tell their customers that the best thing to do if they had encrypted or compressed primary data, that they uncompress it to get the savings in their backups that deduplication promises.

This is wrong on a number… Read more »

There is a lot of discussion around data deduplication for backup these days. (I wish I could deduplicate all the turkey I ate last week.) In fact, Gartner claims that “…by 2012, deduplication will be applied to 75% of backups.” And when asked “Why?” the response was “…deduplication is too compelling to ignore.” But I say “prove it”. So I put together some backup capacity numbers for storing data on tape (non-compressed and compressed) versus… Read more »
