The rsync tool can be found on Linux and Unix systems - and thus also on macOS. It is extremely useful if you want to synchronize two folders - even on different computers. Even if beginners who are not familiar with the terminal often believe that they have no need for such tools: in practice it often looks different, because rsync does a lot more than a simple copying process.
excerpt from the Wiki articles to rsync:
An important feature of rsync is that it can not only copy entire files, but also parts of files. If a file has been changed on the source data carrier, only the changed parts of this file are transferred to the target system (delta coding), which saves time.
You can already see that this type of file synchronization can be exciting, for example for backups or the synchronization of folders between computers.
The hurdle that Mac beginners have with rsync is using the command via the terminal. If you are not used to using the terminal, you often hang on to the documentation for minutes until you have put together the right command.
It is much more intuitive and easier with the GUI grsyncx, which also allows all possible options for the sync. For example, you can protect the Finder attributes so that the date and time of creation or addition are not changed, which would happen with a normal copy process.
How easy it is to use the rsync tool grsyncx is shown in the developer's guide:
