Delta data location has been well applied in data incremental synchronization and other fields. At present,scholars have applieddata chunking algorithms in delta?data location,put forward many excellent data chunking algorithms,and discussed and experimented onthe efficiency of each algorithm, but did not discuss the correctness of data chunking algorithm in delta data location theoretically.Besides,there is no theoretical analysis on the relationship between the size of the delta?
data and the data chunking algorithm,and most ofthem are only explained by the experimental results. Therefore,we abstract the process of delta data location, demonstrate the correctnessof the data chunking algorithm applied in the process and analyze the role of the data chunking algorithm in delta data location. Throughtheoretical derivation,the correctness of the data chunking algorithm in locating delta data is proved,and the relationship between the sizeof delta data and?
the data chunking algorithm is obtained. The conclusion has a certain reference significance for the design of datachunking algorithm applied to delta data location.
