Hi Bob, After my own tests, it seems the "--preserve-numerical-ids" option doesn't solve completely the problem, but however helps to shorten the backup time. With the option enabled, I have a smaller number of changed files. >From what I see, I had files considered as changed in both Case 1 & Case 2 without the option, and only in Case 2 with the option. This is a little bit different from what you found during your own tests, but it is what I observed. Anyway, I will thus shift one of the backup at a different time and problem will very probably be fixed. Once again thanks a lot for your helpful support.
