The dump + restore mechanism operates on device files representing a file system, not a _mounted_ file system, as source. If, for example, your /home partition is /dev/ad0s1e, and you've mounted the target at /mnt, then you could do: # cd /mnt # dump -0 -f - /dev/ad0s1e | restore -r -f - Therefore /home has to be unmounted (or add flag -L to dump from mounted file systems). But note that this will dump the _complete_ file system's content to /mnt as dump cannot be "more selective" here. An alternative is to use rsync or cpdup where you can explicitely address a subtree to be copied instead of the whole file system. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
