Checking output for "Block checksum mismatch" string isn't enough. Error
can be different and due to lack of correct exit code I can't be
confident about volume consistency.

My suggestion based on kiss traditions:

 - 0 exit code if no error or warning
 - all error/warning output to stderr

I this case volume checking is pretty easy:

for i in $(find /bacula/backup/ -type f -mtime +1 -a -mtime -3)
do
  OUTPUT=$(bls -j $i >/dev/null)
  if [ $? != 0 ]; then
    echo "-> Volume $i is damaged"
    echo $OUTPUT
  fi
done
