How to Backup A Mac? 4 Effective Ways Available!

How to free up Mac disk? Backup a Mac and remove useless data!

"Hi there, do you know how to free up Mac disk when the free space is becoming smaller and smaller? I upgraded my MacBook into macOS Sierra 10.12.4 last month and everything works so great on the computer. 
The only issue is that the Mac disk is nearly full with all my personal files, documents, and useful programs, software and apps all stored on it. 
I'm thinking that if I can remove some files and data into an external storage device such as a USB drive or an external hard drive, things will be perfect.
But how? I have too many files and data, and I don't want to copy and paste them one by one into an external storage device. If you know any effective way to backup Mac data and free up Mac disk storage space, please let me know. Thanks."
