    Personally I use a combination of applescript and cli.

    With applescript you create a script that mounts the remote afp volume.

    Eg in script editor
    On run
       try
         mount volume "afp://server/sharepoint" as user name "name" with
    password "crypt"
       on error
        --
       end try
    End run

    Personally I put the mount command inside the try block to prevent error
    dialogs coming up - that is why the -- (a comment line) is after on error -
    it tricks the script into doing nothing on error.

    As you might guess this is plain text - for security when you save it you
    can save as application and tick the run only box - this prevents the file
    being opened in the script editor and read - you can open and run it but not
    see the source.

    This will mount the specific share point - it shows up in
    /volumes/sharepoint - which can then be copied to/from

    I then use the cli to compress/copy files - personally I use stuffit deluxe
    for compression as the deluxe version includes the cli tools and handles
    resource forks / meta data etc.

    #! /bin/sh
    /usr/local/bin/stuff -f sitx -n /pathto/backupfile /pathto/filestobackup

    cp /pathto/backupfile /volumes/sharepoint/backupfile

    Of course you put the date/numbers into the filename as you prefer.

    One gotcha to look out for is if the sharepoint doesn't mount for whatever
    reason the cp step will create a folder in /volumes and will copy locally
    instead of to the server. There is also the option of using scp to get the
    files to the server.

    There is a cli - mount_afp - when I tried it some time ago I had some
    problem(can't remember what now) so I used the applescript instead.

    You then setup cron to run the applescript and the shell script when you
    want.

    With the applescript it is a gui app so in cron you need
    /usr/bin/open /pathto/applescript.app
    Remember the .app is not shown in the finder but is needed for the cli,
    easy to miss.
