Please Help Me Keep My Media Folder Backed Up

I, for whatever reason, cannot seem to get any sort of decent understanding of this app.
I'm trying to keep my media folder synced to another hard drive. I only want it synced one way (meaning I only want to copy the folder from one hard drive to the other, however if I delete something from the source drive I do not want it to automatically delete from the destination drive). I'd like to monitor the destination folder so that any time I add a new file into any of its subfolders, that file gets copied to the destination folder in the correct subfolder
My source folder looks like this:
Media > Videos > 10 different folders with files/subfolders.
Destination Drive has: MediaBackup > Videos
I'm trying to sync videos from source into videos to destination
Please help, I'm desperate.
