It would be more reliable to set the exit code appropriately. 
# special.pl

my $success = 1;

...
if (...) {
   $success = 0;
}
...

exit $success ? 0 : 1;

Then all you need is 

perl special.pl && perl backup.pl

Note that if special.pl dies for any reason, the exit code will be set to something nonzero, so even unexpected failures will also prevent backup.pl from executing.
