Data de-duplication is a technique to reduce storage needs by
eliminating redundant data in backup environment . <br />
data deduplication involves finding and removing duplication
within data without compromising its integrity or fidelity .<br />
only one copy of the data retained on storage media and
redundant data will replace with a pointer to unique data copy .<br />
<strong><br /></strong>
<strong>How data deduplication works?</strong><br />
Deduplication segments an incoming data stream, uniquely identifies data
segments, and then compares the segments to previously stored data. If it found
the segment is unique , it store on disk , if an incoming data segment is
duplicate of already stored data , it create a reference pointer instead of
store whole data .
<br />
Dedupe technology divide data into chunk and use a algorithm to
assign a hash identifier which it compare to previously store to determine if
the data chunk already been stored .Each chunk of data is processed using a hash
algorithm such as MD5 or SHA-1. This process generates a unique number for each
piece which is then stored in an index.<br />
<br />
<b>Deduplication Benefit -</b><br />
-Eliminating duplicate data will shrink storage requirement and
bandwidth efficiency . <br />
<br />
<b>Vendor -</b><br />
1.-EMC Data Domain - application-agnostic deduplication storage system can
attachable as virtual tape library over FC or iSCSI . Its Real-time Inline
DeDuplication and is targeted for secondary (backup) data and optimized for this
flavor of data<br />
2. Netapp ASIS IS Deduplication.<br />
<br />
Faq-<br />
- Data Deduplication won’t work with compressed and encrypted data.</div>
