Article for Creation on Copy Data Hi Davidwr I m writing in regards to an article for creation that you recently reviewed and declined It s the article for creation on Copy Data I was hoping to take a minute to explain why Copy Data is different from data deduplication and data proliferation Simply stated data deduplication can reduce duplicate data within silos of information that exist within an organization Data backup is one such silo where data deduplication is usually applied but there are several other silos of information that data deduplication does not address Take the example used within the article for data deduplication it reads a typical email system might contain 100 instances of the same one megabyte MB file attachment Each time the email platform is backed up all 100 instances of the attachment are saved requiring 100 MB storage space With data deduplication only one instance of the attachment is actually stored the subsequent instances are referenced back to the saved copy for deduplication ratio of roughly 100 to 1 In this instance deduplication is being applied to the backup copy of the email system but that is just one silo where many others exist These silos can include backup snapshot disaster recovery business continuity test and development analytics information sharing and compliance These are all separate copies of entire systems that companies are forced to make and this is what s referred to as Copy Data Deduplication is often applied when making these copies to help reduce the amount of data being stored but it does nothing to eliminate the fact that multiple copies of entire systems are being made As you can see this is a major driver of data proliferation In fact Copy Data may be the reason behind 85 percent of all storage hardware purchases made in 2012 Here s another organization talking about it just this week I can add this and other links to the Copy Data entry but first wanted to further explain the rationale behind this entry As you mentioned much of the article you reviewed discusses the management of multiple copies of data This is because it is important to understand how and why these copies are being made it is the Copy Data If I made some of these clarifications to the article would they address your concerns Thanks
