I meant to reply all to document my solution, but hit reply to Anders only I guess. I was booting off the Live CD and had to soft link /tmp to a drive with some free space. After that everything worked perfect.

Eric I don't have them handy, but I got the header dumpdate warning, which I guess is harmless. Then I would get hundreds of expected next file A found B error. Sometimes it would suddenly give me an abort [yn], if you hit n, then you just get another abort [yn] until you give up. I'll check out your link and give things a few more tries. I figured I must be doing something wrong since dump/restore is so highly recommended as the best choice.

I'm now full of doubt and worry that my real systems are not really backed up. I have used it many hundreds of times. The only problems have been with media failures. don't worry so much about the size. Check the files and see if they are good. Those sizes could be a lot of unused but allocated space in some circumstances and not in others. I really wished this worked as easy as falling out of a boat and hitting water. I've seen that fail before too. jerry Kevin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
