Does rsync compare file size?
Determining which files to send By default, rsync determines which files differ between the sending and receiving systems by checking the modification time and size of each file. If time or size is different between the systems, it transfers the file from the sending to the receiving system.
Is there anything better than rsync?

What are some disadvantages of using rsync?

What is dry run in rsync?

How do I speed up rsync for large files?

Is rsync slow?
