You can use RCP, ssh, and so on to transfer files, of course, through a direct socket connection.

Ubuntu installation: sudo apt install rsync

It is important to note that rsync must be installed on servers A and B, where rsync is running in server mode on Server A and B is running rsync on a client side. This runs the rsync daemon on Web Server A and periodically runs the client on B to back up the content that needs to be backed up on Web server A.
