You don't need an exclude file to avoid /dev and /sys because they are on separate filesystems, so your use of -l takes care of this. Rsync may work, or it may complain that files have changed between building the list and copying them and you'd need to use -x to do the same as -l with tar. Either way, shut down as many services as possible during the copy, particularly anything that uses databases. -- Neil Bothwick If you got the words it does not mean you got the knowledge.
