Abstract
A method for a source storage device to send a source file and a clone file of the source file to a backup storage device. The source storage device sends a data block to the backup storage device to be stored as a target file. Then, the source storage device determines that the source file is associated with the clone file by searching a cloning recorder with a source file ID of the source file. Based upon the determining, the source storage device sends a clone creating request including the source file ID to the backup storage device to instruct the backup storage device to create a clone file of the target file. Thus, the method is capable of replicating the clone file of the file without sending a large number of mapping data.
