Can you install software on the machine doing the fetching?

If so ncftp makes this pretty ncftpget does most of the work for you and gives a nice exit status:

0. Success.
1. Could not connect to remote host.
2. Could not connect to remote host - timed out.
3. Transfer failed.
4. Transfer failed - timed out.
...

So you can just run:
Code:
    ncftpget -u $USER -p $PASSWD ftp://$FILE
    case $? in
        0) echo "All done"
        3) echo "File not there yet"
        4) echo "Network timeout"
    esac

I'd suggest running a script every 15 mins via cron, that checks for the local file and if it hasn't already been fetched it then attempts ncftpget.
It's also worth considering using the ncftpget -DD option to remove the remote file once you have it.

ncftpbatch

ncftpbatch(1)						      General Commands Manual						     ncftpbatch(1)

NAME

       ncftpbatch - Individual batch FTP job processor

SYNOPSIS

       ncftpbatch -d

       ncftpbatch -l

       ncftpbatch -D

OPTIONS

   Command line flags:
       -d      Begin  background  processing  of FTP jobs in the current user's $HOME/.ncftp/spool directory.  This returns immediately, because a
	       daemon process is spawned and ran in the background.

       -l      Lists the contents of the user's job queue.

       -D      This is like -d, except that the process does not become a daemon.

DESCRIPTION

       This program is responsible for processing background FTP requests.  It is normally only run by ncftp and not manually by  a  human  being,
       however you can run it to manually process the FTP job queue.

       The  jobs are spool files written to a user's $HOME/.ncftp/spool directory and have a special format and file-naming convention (which con-
       tains when the job is to be run).  ncftp runs this program when it needs to, but if the ncftpbatch daemon dies unexpectedly the	jobs  that
       are left in the queue will not be processed until another instance of ncftpbatch is run.

       ncftpget  and  ncftpput can also be used to submit jobs for batch processing, using those utilities' -b command-line flag.  If desired, you
       can also manually create the spool files although this procedure is not documented here (see the manual	page  for  ncftpspooler  for  more
       information on how to do that).

DIAGNOSTICS

       ncftpbatch  writes  to its own log file, the $HOME/.ncftp/spool/log file.  This file should be examined to determine if any ncftpbatch pro-
       cesses are actively working on jobs.
