<?php

$aws_creds = array(
	'key' => '<key>',
	'secret' => '<secret>',

$client = Ec2Client::factory($aws_creds);


$volumes = array(
	'mysql-sdf'=>'<volume-id>', // use description to help ID the drive's server and mountpoint
	'mysql-sda1'=>'<volume-id>',
	'website-sda1'=>'<volume-id>'
);

foreach ($volumes as $name => $volume) {	
	$result = $client->createSnapshot(array(
		'DryRun' => false,
		'VolumeId' => $volume,
		// set up the description as auto-servername-time we will use auto* to find and delete rolling snapshots
		'Description' => 'auto-' . $name . '-' . time(),
	));
	echo $name . ' ' . $volume . '\n';
