Honestly, I don't think that the file is not deleted, but you still don't the error message. I suggest you replace 

unlink $file or die "\nCould not delete the backup $file: $!";

print FILE "Now going to delete $file\n";
if(unlink $file) {
  print FILE "$file has been removed (says 'unlink')\n";
  if(-e $file) {
    print FILE "Surprise, surprise! $file is still here\n";
  }
} else {
  print FILE "'unlink' says: $!\n";
  if(-e $file) {
    print FILE "And indeed, we still see $file\n";
  } else {
    print FILE "A miracle occured! $file is gone!\n";
  }
}
