Heroku Backups Gem for Rails 3

Amazon S3 Backup and Restore capabilities for your Heroku app

Things you can do:

• Run automated backups (via cron, or Resque)
• Restore your database from a point in time backup
• Move an entire database from one environment to another
• Restore your production database to your development machine

Installation

Place in your Gemfile:

gem 'heroku_backups'

Place a file name amazon_s3.yml in your config folder:

production:
  bucket: yourapp-production
  access_key_id: your-key
  secret_access_key: your-secret
staging:
  bucket: yourapp-staging
  access_key_id: your-key
  secret_access_key: your-secret
development:
  bucket: yourapp-staging
  access_key_id: your-key
  secret_access_key: your-secret

Rake Tasks

• backups:snapshot # Snapshots the current environment's database and stores on S3
• backups:restore # Restores the latest production backup to your current environment
• backups:restore FILENAME=bkp.1273533572.tar.gz # Restores this backup file from production to your current environment
• backups:restore RAILS_ENV=staging # Restores the latest staging backup from to your current environment
• heroku rake backups:snapshot --app from_application # Snapshot a particular heroku app
• heroku rake backups:restore --app to_application # Restore from production to a particular heroku app
• heroku rake backups:restore filename=bkp.1273533572.tar.gz --app to_application # Restore a backup file to a particular heroku app

Resque Jobs

Since snapshots and restores can potentially be long operations, two Resque jobs have been provided:

Resque.enqueue(HerokuBackups::SnapshotJob)
Resque.enqueue(HerokuBackups::RestoreJob, environment, filename)

environment and filename are optional parameters and instruct the job which backup file to restore and from which environment

Automate backups

Place something like the following task (or add to it) in your lib/tasks/cron.rake

desc "Cron fights for the users"
task :cron => :environment do
  HerokuBackups::Backups.snapshot if Time.now.hour == 2 # runs at 2am
end

or better yet, drop a Resque job!

desc "Cron fights for the users"
task :cron => :environment do
  Resque.enqueue(HerokuBackups::SnapshotJob) if (Time.now.hour % 4).zero? # runs every 4 hours
end

OH $h!t, I need to Restore

Use the backups:restore rake task or to avoid your long running job from getting killed, connect to heroku console and:

Resque.enqueue(HerokuBackups::RestoreJob)
