The --one-file-system option should keep tar from traversing mount points (and your -tvf option isn't going to copy anything...)The only other possibility that comes to my mind is to mount the root drive to /mnt/root read-only. mount the new drive to /mnt/new, and then tar-copy but this may have consequences with the currently mounted root filesystem?If your drives are identical you can boot the install media with 'linux rescue' at the boot prompt, then use dd to copy the raw disk image.cp -a or rsync should work as well as tar for a file oriented copy, and both have --one-file-system options.
Hi, I'm always using "cp -xaP " to some parition (omitting some directories in /) for making a copy of the system, and the copied system is running even the copy is made during a fully running system.
