Python multi-threaded automatic backup Huawei H3C switch configuration and log

Previously tried to back up switch log with expect with bash script, but because it was serially executed, the device took too long and often made a mistake, resulting in incomplete backups. So on the internet to find Python multi-threading related articles, but the basic is based on the TFTP backup run at the time of the configuration file, not according to the Custom Patrol command to obtain the return results, What I want is the effect of using a. vbs script backup like SECURECRT, so this backup script is done based on some examples on the web. Because it is multithreaded execution, the execution time is determined by the length of the command run for the most configured device.
