(beginner, don´t know anything, seeking advice)

USB sticks backup: Documents, pictures, simple stuff to backup.

Whenever new files are added, I copy the folder with the new stuff, and paste that to the the backups with the folder without the new stuff. Get prompted do you want to write over these files. Is this the way to properly backup?

Is there a software that only adds the new files, but skips the files that are the same, and confirms that all backups are now updated and identical?

Tried using robocopy but there is something wonky going on where usb "disconnnects" constantly during the process and robocopy says it has to wait for 30 seconds. But every usb port has been switched permanently on, in the battery savings settings.
