The external size of the file changes every time I do a backup. I think it increases everytime. The size of the files inside (shown once the image file is "mounted") is fine.
But this is terrible. If my image size is 430 gig and the files therein are only 125 gig I will run out of space when I don't need to.
It seems like the sparse image can increase, but is not reduced.
Is it possible that if there are 30 gigs of changes that are needed to be made to the sparse image during a SD Smart Update, the image file increases by that amount, instead of seeing there is plenty of room available in the image file?
I created this sparse image using the Apple Disk utility. I probably created it at 150 or 200 gig orginally. Is this the problem? I was under the impression that you had to do this because image creation within SD didn't work (OS flaw).
Should I create a read/write image file instead, then Superduper to it?
At least then if there was not enough space it would fail, not increase the disk image size.
