Modified by Ben Greenberg (ben at ben<dontspamme>greenberg dot net) December 2008:
  * Utilize the S3 configuration file format used by attachment_fu to keep things nice and DRY.
  * Remove relative paths from require statements so rake file can be placed anywhere in app path.

  This file has been updated accordingly.

== Synopsis

 from the CommandLine within your RubyOnRails application folder
 $ rake -T
   rake s3:backup                      # Backup code, database, and scm to S3
   rake s3:backup:code                 # Backup the code to S3
   rake s3:backup:db                   # Backup the database to S3
   rake s3:backup:scm                  # Backup the scm repository to S3
   rake s3:manage:clean_up             # Remove all but the last 10 most recent backup archive or optionally specify KEEP=5 to keep
                                           the last 5
   rake s3:manage:delete_bucket        # delete bucket.  You need to pass in NAME=bucket_to_delete.  Set FORCE=true if you want to 
                                       #   delete the bucket even if there are items in it.
   rake s3:manage:list                 # list all your backup archives
   rake s3:manage:list_buckets         # list all your S3 buckets
   rake s3:retrieve                    # retrieve the latest revision of code, database, and scm from S3. 
                                       #   If  you need to specify a specific version, call the individual retrieve tasks
   rake s3:retrieve:code               # retrieve the latest code backup from S3, or optionally specify a VERSION=this_archive.tar.gz
   rake s3:retrieve:db                 # retrieve the latest db backup from S3, or optionally specify a VERSION=this_archive.tar.gz
   rake s3:retrieve:scm                # retrieve the latest scm backup from S3, or optionally specify a VERSION=this_archive.tar.gz

== Description

 There are a few prerequisites to get this up and running:
   * You need the aws-s3 gem installed: sudo gem install aws-s3.
   * You will need a 'amazon_s3.yml' file in ./config/.  The file is the same format used by attachment_fu, so if you are using that things will work without any additional configuration.  Note that the bucket_name option is not used by these tasks; bucket name is generated automatically.  See the file in the templates directory for an example with additional options.
   * Copy the aws/s3 directory to your lib directory.
   * Place the rake file tasks/s3_tasks.rake file in your lib/tasks directory.

 Once these two requirements are met, you can easily integrate these rake tasks into capistrano tasks or into cron.
   * For cron, put this into a file like <your.app.name>.backup.cron.  You can drop this file into /etc/cron.daily,
     and make sure you chmod +x <your.app.name>.backup.cron.  Also make sure it is owned by the appropriate user (probably 'root'.):

     #!/bin/sh

     # change the paths as you need...
     cd /var/www/apps/<your.app>/current/ && rake s3:backup >/dev/null 2>&1
     cd /var/www/apps/staging.<your.app>/current/ && rake s3:backup >/dev/null 2>&1

   * within your capistrano recipe file, you can tasks like these:

    task :before_update_code, :roles => [:app, :db, :web] do
       # this will back up your svn repository, your code directory, and your mysql db.
       run "cd #{current_path} && rake --trace RAILS_ENV=production s3:backup"
    end
