发明名称 System and method for checkpointing and restarting an asynchronous transfer of data between a source and destination snapshot
摘要 A method for transferring data from a source computer to a destination computer, and restarting the source computer transmission after a halt of the transmission, has the following steps. The source computer inserts a checkpoint number into a data stream, the data flowing in the data stream. The checkpoint number is stored at the source computer. The data stream is halted in response to an error in a path of the data stream. The destination computer locates the last checkpoint number successfully received before halting the data stream. The last checkpoint number successfully received before halting the data stream is transferred to the source computer; and the source computer compares it with checkpoint numbers stored in the source computer to determine where in the data stream to resume transfer of the data. Transfer of the data is resumed in response to the last checkpoint number.
