How to use the dump command to let the 4GB dumped to one single > tape? If the -a "auto-size" option isn't working to get dump to size the tape properly you can use the -B option to specify how many 1k blocks the tape will hold. For instance, to do a level zero backup of my root partition (with device name /dev/da0s1a) onto a 30 GB tape in device /dev/nht0 I would use the following command: dump -0u -B 30000000 -f /dev/nht0 /dev/da0s1a I've been told it is generally better practice to use the device name to specify the root partition rather than "/". You can get the device name by using the df command. > > Best Regards, > > -Randy > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-questions" in the body of the message > Hope this helps!
