Rather than replying to each of them individually... You're all quite right. I should (and eventually will) make that change. I do appreciate the suggestion. But my mailbox case was just one example of a general issue: --link-dest doing nothing to save backup space in the case where a large file is subjected to a small change. LVM snapshots may offer a solution to this general problem, and it is that idea that I'm hoping to explore here. Thanks again...
