摘要：In backup environments field deduplication yields major advantages. Deduplication is process of automatic elimination ofduplicate data in storage system and it is most effective technique to reduce storage costs. De duplication effects predictably indata fragmentation, because logically continuous data is spread across many disk locations. Fragmentation mainly caused byduplicates from previous backups of the same back upset, since such duplicates are frequent due to repeated full backupscontaining a lot of data which is not changed. Systems with in-line deduplicate intends to detects duplicates during writing andavoids storing them, such fragmentation causes data from the latest backup being scattered across older backups. This surveyfocused on various techniques to detect inline deduplication. As per literature, need to develop a focused on deduplication reducethe time and storage space. Proposed novel method to avoid the reduction in restores performance without reducing writeperformance and without affecting deduplication effectiveness
