Hello,
Here is a way to copy a partition which is mounted without copying all the other partitions that are under it.
Let /patha be the mountpoint of the partition from which you want to copy (it could even be the root path /).
Let /dev/new be the device to which you want to copy the data.
mkdir /var/tmp/src # The bind mount is the crucial thing! mount --bind /patha /var/tmp/src mkdir /var/tmp/target mount /dev/new /var/tmp/target cd /var/tmp/src # I find this a neat way to copy all files # and permissions find . | cpio -pdum /var/tmp/target umount /dev/new umount /var/tmp/src rmdir /var/tmp/{src,target}And you are done! I hope the above commands are self-explanatory. If not, then I can explain further.
