Abstract: Multiple servers sharing a distributed file system are used to perform copies of regions of a source file in parallel from a source storage unit to corresponding temporary files at a destination storage unit. These temporary files are then merged or combined into a single file at the destination storage unit in a way that preserves the inode structure and attributes of the source file. A substantial speedup is obtained by copying regions of the file in parallel.
