I've never had a problem with clones being identical in size to the originals. OTOH, the originals are usually boot drives and I'm pretty careful to keep a bit of free space on them, one side effect of which is that there's always some spare room on the clone for the cloning process. > If it is important, it means I have to erase my backup drives to make > Super Duper's destination partition 15 percent bigger than they are. > > Pages 55 and 56 of the Super Duper User Guide say that if your source > drive uses 10.65 gigabytes, ensure that the destination drive has at > least 11 gigabytes free. The difference between 10.65 gigabytes and 11 > gigabytes is only about three percent – not 15 percent. 15% seems overkill. I do try to make sure that there's always at least 5% free space on my drive, though. The last thing I want is a full disk. Okay, maybe next-to-last (after a crashed disk)... -- Plain Bread alone for e-mail, thanks. The rest gets trashed.
