Most thorough Backup: Use Libraries or Users via copy/paste?

Most thorough Backup: Use "Libraries" or "Users" via copy/paste?
For simplicity I prefer to do a copy/paste backup to an external hard drive.
Is it more thorough and effective for me to copy "Libraries" or "Users" to paste to the drive?
I am only want to backup Data.
Data only. Not O.S.
"Libraries" contains: Documents, Music, Pictures, & Videos.
"Users" has is larger in GB.

What do you want to backup - user data or the OS.

Data only. Not O.S.
"Libraries" contains: Documents, Musics, Pictures, & Videos.
"Users" is larger in GB.

For those you can use Copy/Paste (the folders) or this: Context Menu - Add Copy To Folder and Move To Folder

You cannot copy (from) a library. But you can paste to a library - it will then paste into the default folder as shown in the library properties.

You can only copy (from) a folder or file.

Oh hey, I didn't notice that before. No "included" folder can be copied; just its contents!

That's correct. If you right click on a library and say 'copy', nothing will happen. But if you say 'paste', the clipboard content will land in the default folder of that library.

However, if you right click on a folder and say copy, it will go to the clipboard.
