Backup Dokku apps with Dropbox

gistfile1.rb

# 0. Install Ruby on your server: https://gorails.com/setup/ubuntu/16.04
# 1. Install Whenever gem on the server: https://github.com/javan/whenever
# 2. Cd to `/root/backup/`, install Dropbox Uploader (https://github.com/andreafabrizi/Dropbox-Uploader) into it
# 3. Go to https://www.dropbox.com/developers/apps, create a new app
# 4. Generate a new Access Token for that app
# 5. Run `./dropbox_uploader.sh` and import the Access Token
# 6. Create a `config` directory
# 7. Run `wheneverize .`
# 8. Edit `config/schedule.rb` file like this (it's just an example):

dropbox_path = 'a_path_related_to_this_server' # For example, 'my-server-backups'

every 3.day, at: '0:00 am' do
  %w(app1 app2).each do |app|
    command "dokku redis:export #{ app }-rdb > /root/backup/dumps/#{ app }/redis.rdb"
    command "dokku postgres:export #{ app }-db > /root/backup/dumps/#{ app }/pg.dump"
  end

  command "/root/backup/dropbox_uploader.sh upload dumps #{ dropbox_path }"
end

# 9. Now run `whenever --update-crontab` and `crontab -l`
# 10. Be happy with regular backups! :)
