Most past studies either were of a small static snapshot or covered only a short periodthat was not representative of how a backup system evolves over time. For this article, we rst collected 21months of data from a shared user le system; 33 users and over 4,000 snapshots are covered. We then analyzedthe data set, examining a variety of essential characteristics across two dimensions: Single-Node deduplicationand Cluster deduplication .

deduplication ratios. Moreover, the data that some users share with others had a much higher deduplication ... understanding such data sets’ characteristics, we can design more e￿cient storage systems [10, 11, 35]. However, data sets may vary signi￿cantly …
