Something like this works for me: dump -0aub 64 -f vanheden:/dev/nrsa0 / dump -0aub 64 -f vanheden:/dev/nrsa0 /usr dump -0aub 64 -f vanheden:/dev/rsa0 /var (this way it'll rewind when done) authentication is through rsh, which maybe is dangerous for you? Variations on that theme e.g. tar -c -v -p -f - -b 20 directory | ssh -c arcfour vanheden dd \ of=/dev/rmt/0n obs=20b should do just as well I imagine. Try not to use a too computer intensive encipherment though. Anyway man dump and man restore is prolly what you want. /M ---------------------------------- Michael Josefsson, MSEE mj@isy.liu.se This message was sent by XFMail running on FreeBSD 3.5-STABLE ---------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
