Make a rough calculation of the image size---50 or 60 percent of your occupied space.
If occupied space is 200 GB, figure maybe 120 for the image.
Figure you might want to keep 2 or 3 images. Say 400 max total. No need to keep 5 or 6 for most people. Make a new image monthly and delete the oldest.
If your external is 1 TB, maybe you are crowding it. If 2 TB, maybe not. I don't know the size of your external.
