Got it! The Paragon EXT Driver works perfectly (and copies files INTO ext4 which root:root permissions, so ext 4 is safely receiving those files).
Just in case anyone was wondering: In /etc/fstab for the /data ntfs partition I was using "0 0" as the mount permissions at the end. This caused Ubuntu to save files with invalid ntfs permissions into the /backupdata. Ubuntu can still read/write those files no problem, but when you boot into windows and do a chkdsk to check your files, it will delete those inodes and you will see checkdsk saying "invalid permissions on file abc.. found" as it scrolls. You should use "0 2" and the "ntfs-3g" in fstab to fix this. But I hate ntfs now because windows randomly does a checkdsk and deletes stuff, so I just leave my /backupdata as ext4 and this is better. Then the PARAGON driver below works to mount the ext4 but checkdsk will never run. Instead if you need it, ubuntu or fedora or any linux uses 'fsck -y /dev/sdb1' to fix if you need to fix files. :)
Here is the driver if anyone needs it:
