Why? The point here would be to explicitely declare "I don't care about directories that changed since I passed them on this particular backup run; they'll get caught on the next backup run". > You can, however, explicitly break the runs at top-level directory > boundaries and mount points if you have a problem with the size. That doesn't always work; it certainly doesn't work in my case. Millions of files scattered unevenly around a single file system; I don't even know where the concentrations are because it takes so long to run du/find on this filesystem, and it degrades performance in a way that makes the client upset. -Robin -- They say: "The first AIs will be built by the military as weapons." And I'm thinking: "Does it even occur to you to try for something other than the default outcome?"
