Question

Is there a rake task for backing up the data in your database?

I already have my schema backed up, but I want to make a backup of the data. It’s a small MySQL database.

Answer 1

The below script is a simplified version taken from eycap, specifically from this file.

set :dbuser 'user' set :dbhost 'host' set :database 'db'  namespace :db do   desc 'Get the database password from user'   task :get_password do     set(:dbpass) do       Capistrano::CLI.ui.ask 'Enter mysql password: '     end   end    task :backup_name, :only => { :primary => true } do     now = Time.now     run 'mkdir -p #{shared_path}/db_backups'     backup_time = [now.year,now.month,now.day,now.hour,now.min,now.sec].join('-')     set :backup_file, '#{shared_path}/db_backups/#{database}-snapshot-#{backup_time}.sql'   end    desc 'Dump database to backup file'   task :dump, :roles => :db, :only => {:primary => true} do     backup_name     run 'mysqldump --add-drop-table -u #{dbuser} -h #{dbhost} -p#{dbpass} #{database} | bzip2 -c > #{backup_file}.bz2'   end end 

Edit: Yeah, I guess I missed the point that you were looking for a rake task and not a capistrano task, but I don’t have a rake one on hand, sorry.
