Abstract:
Rsync is an efficient algorithm for file synchronization on unix/linux, it can synchronize update files and directories in two computers, and find out different blocks to reduce the data transmission.However, the core algorithm of Rsync use the Fixed-Sized Partitioning for the chunk of destination file,sometimes,for example,only one character is inserted,could reduce the synchronization efficiency. With the research of the content-based chunked algorithm is deep, the improvement for core algorithm of Rsync is a attempt, it is important to data recovery from disaster research.
