Rsync is a very flexible network-enabled syncing tool. Due to its ubiquity and its popularity as a tool for system scripts, it's included on most Linux distributions by default. It efficiently copies and sync files to or from a remote system. It’s faster than scp because rsync uses a remote-update protocol which allows transferring just the differences between two sets of files. The first time, it copies the whole content of a file or a directory from source to destination but from next time, it copies only the changed blocks and bytes to the destination.

Secure Shell (SSH) is a protocol that provides secure command-line access to a remote server. By using SSH, you can remotely log in and run commands as if you were sitting right at the server.

The benefit of using SSH over other methods of remote access is that, as the name suggests, communications are securely encrypted, protecting the traffic flowing to and from the server. Data is encrypted at both ends of the client/server connection using a digital security certificate and access credentials are also protected.
