Simple PHP script to backup EC2 EBS volumes. Nice to include as a daily Cron job.

ebs-backup.php

#! /usr/bin/env php
<?php
//Don't forget to setup credentials for the AWS API.
require_once('/usr/lib/aws-php-sdk-1.3.1/sdk.class.php');
$ec2 = new AmazonEC2();

$volumes = array(
        'vol-xxxxxxxx' => '-- Your snapshot description here --',
        'vol-xxxxxxxx' => '-- Your snapshot description here --',
        'vol-xxxxxxxx' => '-- Your snapshot description here --'
);

foreach($volumes as $volumeID => $snapshotDesc)
{
        $response = $ec2->create_snapshot($volumeID, $snapshotDesc);
        $OK = $response->isOK();
        if(!$OK)
                var_dump($response);
}
?>

Hmmm... yeah.... can't get any more simple than this, I'm afraid. :-/
