摘要: A mechanism is provided for improved file synchronization of a magnetic tape. destination device determines whether one or more checksums exist in an extended attribute associated with identified file. Responsive to existing the file, reads out without accessing The transmits source device. segments data new into fixed-length blocks that do not overlap another. calculates each blocks.
