I've been dumping and restoring a test system today, and I'm have very

/mnt/test.root.dump. /mnt is a ufs formated usb drive. After the
dump, I've even done a restore -rNf /mnt/test.root.dump just to make
sure it doesn't complain out the dump file.

I've read the handbook, found a few articles, googled all the errors.
The header dumpdate thing is harmless, the expected next file is from
it being a live system, but I'm not ending up with a system that is
very usable. Doing a df, I see that sometimes I end up with a
restored slice that is about the same size as my dump file, sometimes
less than half. I know I'm not being very specific with what's not
working, but is anyone really using dump/restore and having success
with the restore part? I'm now full of doubt and worry that my real
systems are not really backed up.

I really wished this worked as easy as falling out of a boat and hitting
water.

i wrote this up:

http://mikestammer.com/dokuwiki/bsd:dumprestore

after setting up dump/restore for my backup solution. i used it to migrate
from old hard drives to a RAID1 setup on a 3ware controller and everything
went well.

what errors are you seeing?

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.

Thanks, Kevin.
