Did you use the -u switch on your dump command. It looks like you must have if dumpdates is written OK. I haven't tried this and, if lacking a -u isn't the problem, unfortunately I do not have an answer to your main question. But, I wonder why you chose level 9 for your change dumps. It sort of defeats the system. It would be more normal to use level 1. I know that [some much] earlier versions of BSD dump only took levels up to 5, but I presume that since they include up to 9 in the documentation it should work. ////jerry > > Anybody has any idea ? > > Best regards, > Paolo Tealdi > > > > Ing.
