Survey on Data Deduplication for Cloud Storage to Reduce Fragmentation

Reshma A., R. D.
2016 International Journal of Computer Applications  
Data Deduplication is an important technique which provides better result to store more information with less space. Cost and maintenance of Information backup storage system for major enterprises can be minimized by storing it on Cloud Storage. Data redundancy between different kinds of data storage gets minimal by utilizing data deduplication method. By giving each application differently and storing the associated information distinctly the overall disk usage can be enhanced to a great
more » ... Cloud backup systems uses data deduplication to eliminate duplicate chunks that are present in multiple files. The duplicate chunks are substituted with the references to already present chunks through deduplication, without storing it again on cloud storage. The successive chunks are actually stored in scattered form in backup system in numerous segments (the storage unit of cloud).
