1. Do an SVN hotcopy so you get all your stuff
2. tar up the entire directory
3. split and bzip the files using p7zip so they can fit on hosted drives ( 2 Gb files )
4. copy them to S3 or any online service

Commands:

/usr/bin/svnadmin hotcopy /path/to/svn/repository /path/to/destination

tar cvf /path/to/backup/svnbackup-`date +%Y-%m-%d`.tar /path/to/destination/*

/usr/local/bin/7z a -tbzip2 -v2g svnbackup-`date +%Y-%m-%d`.tar.bz2 /path/to/backup/svnbackup-`date +%Y-%m-%d`.tar

Copy them over using any scripts you have. I personally use jstream on a linux server to move stuff to Amazon S3

Prerequisites

1) NuSoap Libraries: http://sourceforge.net/projects/nusoap/

Sample Code

<?php
    // add nusoap library
    require_once('lib/nusoap.php');

    // create a soap client
    $client = new nusoap_client('http://localhost/sugar/soap.php?wsdl','wsdl','','','','');

    // Login
    $user_auth = array(
                'user_auth' => array(
                    'user_name' => 'ipshift-user',
                    'password' => md5('ipshift-password'),
                    'version' => '0.1'),
                 'application_name' => 'ipshift-crm'
        );

    $result = $client->call('login',$user_auth);

    // output the session id
    echo '<h2>Session Id:</h2>';
    print($result['id']);

    // Now Prepare a Contact
    $set_entry_params = array(
              'session' => $result['id'],
              'module_name' => 'Contacts',
              'name_value_list'=>array(
                            array('name'=>'first_name','value'=>'FirstName'),
                            array('name'=>'last_name','value'=>'LastName'),
                            array('name'=>'email1','value'=>'vmehta@ipshift.com'),
                            array('name'=>'lead_source','value'=>'Web Site'),
                            array('name'=>'phone_work', 'value'=>'1231231234'),
                            array('name'=>'account_name','value'=>'IP Shift')
                            )
                        );

    // Now Add the Contact
    $result2 = $client->call('set_entry',$set_entry_params); 

    // Show the result
    echo '<h2>Add Dump:</h2>';
    print_r($result2);
?>
