FTP with Script

Dear, Linux guru
I have a data server and backup server running in RedHat 7.3.
Is there any way that I can use a script to FTP a server and upload a file?
I have a data server that I want to backup to a backup server. At this time, I can run tar command to get a tar in data server. Then I want to FTP to backup server to upload tar file.
I have done similar to this in Windows system and I believe Linux is better than Windows. I have tried a few different ways but it did not work.
Any idea would be appreciated.

Thanks in advance.
