Data Deduplication

Data de-duplication is an effective way to get rid of redundant data generated through big data aggregation. A de-duplication system identifies and eliminates duplicate blocks of data and hence significantly reduces physical storage requirements, improves bandwidth efficiency, and streamlines data archival efforts.

Calsoft assists ISVs in developing data de-duplication solutions that protect a wide range of environments, right from small distributed offices to the largest enterprise data centers.

Block – Level Deduplication

Block-level data de-duplication operates on the sub-file level. As its name implies, the file is typically broken down into segments, i.e. chunks or blocks, that are examined for redundancy as compared to previously stored information. Calsoft assists in the development and management of block-level deduplication operations.
