China DOS Union

I often need to back up data from a host on the LAN to another host, and the total copy time is about 12 hours or more. Usually I copy at night so it doesn't take up resources. But the network often disconnects unexpectedly, causing the copy job to be interrupted.
Now I'm looking for some code to copy automatically and monitor the network at all times, so that if there is a disconnect, it can continue copying after the network reconnects.
Hope an expert can give some advice. Thanks!

Try to copy the folder as much as possible, and use the /z parameter during the copy process

Try recopy~~~ as for checking whether the network is working smoothly~~ well, well....... waiting for an expert~~~~ should it check during the copying process, then sleep for a while... and then start copying again?
Try using a script like AU3, it should be easier to implement that way。。。。。。。。。。。
