That's not correct.  See 'man fstab'. It should be 

    device  mount-point  filesystem-type  options   dump   fsck

So you should have:

UUID=259ec5ea-e8a4-465a-9263-1c06217b9aaf  /mnt/backup  ext4   x-systemd.automount,x-systemd.idle-timeout=15min,noauto 0 2

Yeah, you put them in the wrong place.
