Hi Den:

# [ -d $rep_backup -o -h $rep_backup ] && echo "is a dir or symlink" || echo "ok"

That is, if the variable represents a directory or a symbolic link, the test is true otherwise false.

You can also simplify Ivan's and reverse the sense of JRF's by:
if [ ! -d $rep_backup -a ! -L $rep_backup ]; then
