Well, I think I managed to do it. I'm in the middle of a 1.09 TB backup that has been running since this morning. What I think did it, if someone will test/confirm on another system: 1. Excluded all partitions. No partitions to back up. 2. Do a backup. Get an error about nothing to back up. 3. Add in something small and tiny to back up, like a mounted download. 4. Back up. Something goes to the backup disk 5. Now set the list of partitions back to what you want to back up. 6. Backing up, it should (maybe? Hopefully?) back up everything. As I said: I don't know for certain that this does it, but if someone else can verify this, great. In my case, #3 was actually just a small partition on the drive (not a mounted download), so that one partition (only) has not (yet) been refreshed to the drive. _______________________________________________ MacOSX-talk mailing list MacOSX-talk@omnigroup.com http://www.omnigroup.com/mailman/listinfo/macosx-talk
