deduplication has been around at least for the most primitive forms since the 1970 & # 39; s. It originally started because the company wanted to store large amounts of customer contact information without large amounts of storage space. One of the first ideas was to go through and remove duplicate information. For example, a company might have a delivery address and a billing address for a particular client. In these cases, they would be the same addresses combined into one file. This was done by data entry clerks, who review the data line by line, and get rid of duplicates.
Of course, the amount of staff needed for this was extensive, and there was a very long time. Sometimes the multiple existing data filtering process would take months. However, considering that most of those made of paper, was not a major problem. The big problem along the cam when widespread use of computers in office environments.
The widespread use of computers and the explosion of the Internet, the amount of available data is exploding as well. Backup systems were established to ensure that companies are not losing any data. As time passed, floppy drives and other external hardware used to store this data. Unfortunately, this data is about to fill these plates, and the amount of space to store the data was extensive.
The cloud storage and other alternative storage options, companies set off a virtual storage environment. He also moved over disk-based storage, tape, simply because it was cheap and require less space. However, these storage solutions are expensive and difficult to handle, because the data is increased. The same data is saved again and again. This redundant data is not necessary and took up valuable storage space.
Companies have made backup plans to eliminate duplication, but there was no quick way to do this. This is when IT professionals began working on algorithms to automate the deduplication process. Generally, this case has a case by case basis, the goal is to optimize your backup files. Algorithms can also be customized to meet their individual needs.
There was no one in the company that came up with the idea to deduplication. Instead, they must find ways to reduce duplicate files to a common need in the industry. There was a lot of computer scientists who advanced deduplication technology is a significant but not a scientist who is solely responsible for it. While many claimed credit for the term & # 39; data de & # 39; One person alone can not claim credit for the idea itself.
Instead, the creation of deduplication was more a compilation algorithms. The people in the IT industry saw the need to reduce the copies of the data, and filled with the need to reduce the file be duplicated by creating algorithms. As data grows, people will still find a way to compress data in a way that makes it easy to store.
