Question

We use Heroku’s PG Backups which has been great http://addons.heroku.com/pgbackups

I’m currently manually downloading the backups everyday to my computer and then uploading it to my S3 account. Does anyone know how to setup a cron job to automatically create a backup (daily is fine) and send it directly to my S3 account?

Answer 1

If you add this to lib/tasks and have the cron addon running herkou will run this:

namespace :heroku do
  desc "PostgreSQL database backups from Heroku to Amazon S3"
  task :backup => :environment do
    begin
      require 'right_aws'
      puts "[#{Time.now}] heroku:backup started"
      name = "#{ENV['APP_NAME']}-#{Time.now.strftime('%Y-%m-%d-%H%M%S')}.dump"
      db = ENV['DATABASE_URL'].match(/postgres:\/\/([^:]+):([^@]+)@([^\/]+)\/(.+)/)
      system "PGPASSWORD=#{db[2]} pg_dump -Fc -i --username=#{db[1]} --host=#{db[3]} #{db[4]} > tmp/#{name}"
      s3 = RightAws::S3.new(ENV['s3_access_key_id'], ENV['s3_secret_access_key'])
      bucket = s3.bucket("#{ENV['APP_NAME']}-heroku-backups", true, 'private')
      bucket.put(name, open("tmp/#{name}"))
      system "rm tmp/#{name}"
      puts "[#{Time.now}] heroku:backup complete"
    # rescue Exception => e
    #   require 'toadhopper'
    #   Toadhopper(ENV['hoptoad_key']).post!(e)
    end
  end
end

task :cron => :environment do
  Rake::Task['heroku:backup'].invoke
