Try this bash script to do the copy only if the fs is mounted.
--- Cut Here ---
#!/bin/bash
df | grep -q "\/local_dir"
ESTAT=$?
if [ ${ESTAT} -eq 0 ]; then
### Mounted
# Do copy here
else
### Not Mounted
# Put error processing here; maybe the mount command? or
# email the admin?
fi
--- End Here ---
