That's backward - you've just told it to honor nodump on full backups. To disable it for all backups, you want "nodump -h 10". Of course, that sort of defeats the purpose of turning it on in the first place. I mean - why would you turn on the nodump flag for a file other than because you didn't want it backed up? http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
