Maybe I am missing something....but why doesn't this work?

  You need to bzero the sockaddr_in structure (backupserver) before putting
anything into it.

  I compiled your program as-is (with a different host name) and it didn't
work.  I then added the line "bzero((char *) &backupserver,
sizeof(backupserver));" right before "backupserver.sin_family = AF_INET;" and
it worked fine.
