Dear Stefan, I'm picking up this oldish topic, which I'm back to after a month of distractions. > Can you still create dumpfiles containing the revisions that > did not get lost?

Unfortunately, it appears I cannot create dump files from revisions after a missing revs/ file gap. All the dumpfiles I created which began with a revision past a point of continuity were unusable. They collapsed upon re-import (svnadmin load …) into a single revision instead of hundreds of revisions. Any idea why that might be or how I might get around it? Thanks for your continued help, /eiren
