Data deduplication and the resulting compression lowers the storage footprint of the data, reducing disk expenditure and overall storage costs. Reducing the storage footprint of data also has the secondary benefit of improving the efficiency of backup and recovery processes. However, storage and backup vendors deliver data compression through deduplication technologies that primarily operate at the file and block level, and are therefore most effective when applied to unstructured data. In the current economic and environmental climate, IT managers are being driven to maximise reductions in storage consumption and must therefore consider deduplication technologies that can be applied to structured and unstructured data. This whitepaper discusses the deduplication and compression techniques that enable dramatic reductions in the storage footprint of database data.
