Code:

I think Scott was talking of the shell's noclobber option which works on redirections but not for cp.

No, this option is in GNU cp/coreutils version 8
Code:
man cp
...
       -n, --no-clobber
              do not overwrite an existing file (overrides a previous -i option)

cd /p2/arch/log
for f in *
do	[ -f "$f" ] || continue		# If this isn't a regular file, skip it.
	[ -e "/p2/bkp/$f" ] && continue	# If a backup already exists, skip it.
	cp "$f" /p2/bkp			# Make a backup copy.
done

This should work with any shell based on Bourne shell syntax (e.g., ash, bash, dash, ksh, sh,zsh, etc.), but will not work with csh and its derivatives.
