My experience with rsync has been between hosts on the LAN and backups from
a desktop to the MediaSonic Probox external drive. My web searches for the
appropriate syntax between two drives on the same host finds nothing
suitable.
If I mount the new drive on /media/hd0 I wonder if this syntax will work:
rsync -av /home /media/hd0/1
rsync -av /opt /media/hd0/2
rsync -av /data1 /media/hd0/3
Leaving off the source final slash will create the directory name and
contents on the target's partion.
Comments welcome,
Rich
