Since dump works on a file system I cd to the destination mount point and work from there and I don't have to put the cd in the middle. cd /backup/root dump -0aLf - / | restore -rf - works fine. You don't have to newfs each time, but you do need to do something to clean out the destination file system so I guess newfs works as well as rm -rf. ////jerry > > I guess I can do something like: > mount /dev/ad1s3a /backup/root > mount /dev/ad1s3d /backup/var > mount /dev/ad1s3f /backup/usr > /usr/local/bin/rsync -avHxS --delete /usr /backup/usr > for /usr / and var > > OR > > #!/bin/sh > newfs /dev/ad0s3a > newfs /dev/ad0s3d > newfs /dev/ad0s3f > mount /dev/ad0s3a /backup/root > mount /dev/ad0s3d /backup/var > mount /dev/ad0s3f /backup/usr > (/sbin/dump -L -0f - /)|(cd /backup/root ; /sbin/restore -rf -) > (/sbin/dump -L -0f - /var)|(cd /backup/var ; /sbin/restore -rf -) > (/sbin/dump -L -0f - /usr)|(cd /backup/usr ; /sbin/restore -rf -) > umount /backup/root > umount /backup/var > umount /backup/usr > tunefs -n enable /dev/ad0s3d > tunefs -n enable /dev/ad0s3f > > This gives me a perfect copy, BUT there is a risk if something goes > wrong when I have newfs'd the backup drive. > > Any advice? > > -- > dick -- http://nagual.st/ -- PGP/GnuPG key: F86289CE > ++ Running FreeBSD 6.1 ++ The Power to Serve > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" >
