Smart Update disk image?

[DavidCB]

What if the disk image is just one of many files on a drive and you are Smart Updating the whole drive? (In this case the disk image would not be mounted.)

Then the bands of the bundle that have changed would be copied. In the case of a sparse image, the whole thing (if changed).

In the case, then, where one wants to keep synced two external drives which contain sparse images, the most efficient procedure without a custom script would seem to be, first, to mount the sparse images on both drives, then perform a copy between them; finally, perform a copy between the drives, which will skip the sparse images and copy the other modified files on the source drive. But there is probably something wrong with this procedure, yes?

Yes. The dates of the band files will be different, regardless of the state of their contents, and so will be copied again.
