I don't know about the first one, but BackupPC_fixLinks.pl can *definitely* be run while BackupPC runs. For serious corruption, you may want to grab the patch I posted a few days ago; it makes the run *much* slower, but on the plus side it will fix more errors. OTOH, the errors it fixes only waste disk space, they don't actually break BackupPC's ability to function at all. -Robin -- http://singinst.org/ : Our last, best hope for a fantastic future.
