Survey on Fragmentation for Deduplication in Backup Storage
Abstract:Abstract:In backup environments field deduplication yields major advantages. Deduplication is process of automatic elimination of duplicate data in a storage system and it is most effective technique to reduce storage costs. Deduplication effects predictably in data fragmentation, because logically continuous data is spread across many disk locations. Fragmentation mainly caused by duplicates from previous backups of the same backup set, since such duplicates are frequent due to repeated full backups containin… Show more
