The abolition of duplicate data has been present, at least in its most primitive form, since the 1970s. It started at first because companies wanted to store a large amount of customer contact information without using too much storage space. One of the first ideas was to review and remove duplicate data. For example, a company might have a shipping address, and a billing address for a specific customer. In these cases, those matching addresses will be combined into one file. This was done by data entry writers who review the data line line and eliminate duplicates.
Of course, the size of the staff needed to do this was extensive and very time consuming. Sometimes, it takes months for the duplicate data to be removed. However, given that most of this happened on a hard copy, it was a huge problem. The big problems are widespread computer use in office environments.
With the widespread use of computers and the Internet explosion, the amount of data available also exploded. Backup systems were created to ensure that companies will not lose all of their data. Over time, floppy disks and other external devices were used to store this data. Unfortunately, this data will shortly fill these drives and the storage space to store this data is large.
With cloud storage and other alternative storage options, companies have started moving storage to a virtual environment. They also moved to disk-based storage on tape, simply because it was low-cost and required less space. However, these storage options were expensive and difficult to manage as data grew. The same data will be saved over and over again. This extra data was not needed and took valuable storage space.
Companies may have customized their backup plans to eliminate duplication, but there was no quick way to do this. That's when IT professionals began working on algorithms to automate the process of deleting duplicate data. They generally do this on a case-by-case basis, with the goal of improving their backup files. Their algorithms will be customized to meet their individual needs.
Not a single company came up with the idea of eliminating duplicate data. Instead, the need to find a way to reduce duplicate files was common in the industry. There were many computer scientists who developed the technique of eliminating duplicate data dramatically, but not a single scientist is responsible for that. While many have called for reliance on the term canceling duplicate data 'same, no one can claim credit for the same idea.
Instead, algorithms created more than one duplicate data collection. People in the IT industry saw the need to reduce redundancies in data and have filled that need to reduce these duplicate files by creating algorithms. As data increases, people will continue to look for ways to compress data in a way that makes it easy to store it.
