If it is ok to use PHP as shel script you can use my latest script with latest AWS PHP SDK. This is much simpler because you do not need to setup environment. Just feed script your API keys.

How to setup

1. Open SSH connection to your server.

2. Navigate to folder

   $ cd /usr/local/
   

3. Clon this gist into ec2 folder

   $ git clone https://gist.github.com/9738785.git ec2
   

4. Go to that folder

   $ cd ec2
   

5. Make backup.php executable

   $ chmod +x backup.php
   

6. Open releases of the AWS PHP SDK github project and copy URL of aws.zip button. Now download it into your server.

   $ wget https://github.com/aws/aws-sdk-php/releases/download/2.6.0/aws.zip
   

7. Unzip this file into aws directory.

   $ unzip aws.zip -d aws 
   

8. Edit backup.php php file and set all settings in line 5-12

   $dryrun     = FALSE;
   $interval   = '24 hours';
   $keep_for   = '10 Days';
   $volumes    = array('vol-********');
   $api_key    = '*********************';
   $api_secret = '****************************************';
   $ec2_region = 'us-east-1';
   $snap_descr = "Daily backup";
   

9. Test it. Run this script

   $ ./backup.php
   

   Test is snapshot was created.

10. If everything is ok just add cronjob.
