What is deduplication?
DEDUPLICATION is a process used to remove redundant data. During the process, the computer's hard drive is scanned for large data sequences across comparative windows. When scanning duplicate data, a sequence of eight kilobytes or more is usually selected. If the sequence is found elsewhere in the storage system, it is referred to the duplicated file rather than re -stored. Duplication of data occupies an unnecessary room in the system and when foreign data is removed, it leaves the user more storage space on the computer. This allows the system to run faster and more efficiently because it is not saved with other data. In addition, improving the bandwidth is always more evident when the computer has more free space. However, which is indexed if it should be needed. The same exact data can often be stored at up to 100 different locations on the hard disk. If everyone takes one megabyt space, deduplication will reduce this space on the hard disk from 100 megabytes to one. The process works by archiving data and other space thatRow is gaining, it is very beneficial for your computer's hard disk.
Other benefits of deduplication include a reduction in the amount of backup space required by up to 90 percent, cost reduction such as power, space and cooling requirements, higher service levels, eliminating many different types of errors and restoring data at several different points. The disadvantage of deduplication is that it identifies duplicate data using cryptographic hash functions that may be unreliable, and collisions or other type of error by resumer data loss. Also, if the person who enabled this procedure is not aware of redundancy, the reliability of the computer may be adversely affected.
data deduplication works the first segment of each processed piece. Each segment is identified and compared with data that are already in the system. If the data is unique, they are stored on the disk. If this is a duplicate piece of data, instead ofcreates a link. Deduplication can be implemented using the DATA DATA software that works with data and storage systems for filtering through data, linking, elimination or storage of each byte, as needed.
