A few things.

First, are you sure you want to use (and understand) the Safety Clone? If not, while you can create a partition for it, let's concentrate on your backups first, and move to that later.

The 2nd partition -- the backup -- you wouldn't do with Drag and Drop. You'd use SuperDuper! to copy from your boot volume to the partition, using "Backup - all files" and "Smart Update". That'd copy all new files to the drive automatically.

BUT, it will also erase any files that were removed. So, if you delete them off the original drive, they'll be deleted from the backup the next time around.

If you don't want to that to happen, you'd use "Copy Different" or "Copy Newer" (probably copy different). BUT, again, that won't ever delete anything, and your drive can fill...
