If you must copy exactly what you currently have then I'd use a variation on the handbook method which has already been suggested at http://www.freebsd.org/doc/handbook/backup-basics.html Rather than example 18-1 or 18-2 I'd pipe dump directly into restore. Do this once for every filesystem. Something like: ( cd /; /sbin/dump -0uanf - / ) | ( cd /newmount; /sbin/restore -rf - ) Where /newmount is the temporary new mount point for your new drive. Left preparation of new disk as an exercise for the reader. However there is a good argument to be made for making a totally new installation of FreeBSD. Then go through the original disk picking up the necessary files to customize for your use. As you find these files put their names in a file named something like files.list that in the future one could "tar -T files.list" (thats an incomplete example) to do a minimal quick backup or restore of only the files which are unique to your machine. This is an opportunity to find these files, and to practice using tar -T to lift them from one drive and write them to another. I wouldn't try to move the ports collection with the above technique. However it would be a good idea to save a list of installed ports that one could use to reinstall. -- David Kelly N4HHE, dkelly@HiWAAY.net ======================================================================== Whom computers would destroy, they must first drive mad.
