Well, if the script failed with an error, cron should have sent you an
email (or the user the script runs as, anyway).

If you didn't have an error, you could run a separate cron that checks
whether there are recent backup files and emails you if not (find ...
-mtime -1).

Or, if you want to make sure the restore has worked check the database
for a row with a recent timestamp.
