mysql - 如何在Rails 4中自动备份Mysql数据库

Question

我在 Windows 中使用 Rails 4 和 Mysql2 作为数据库。我想每秒自动备份我的数据库。因此，在我指定的路径中应该每秒生成一个文件夹，并且还必须发送一封电子邮件以及数据库作为附件。每当 gem 用于此目的时，我都会使用它，但我无法获取我必须在日程表中写入的内容.rb 文件。

schedule.rb file

every :day, :at => '12:05am' do
  rake 'task_namespace:autobackup' , :environment => 'development',   :output => 'log/autobackup_mail.log'
  # rake 'task_namespace:autobackup_with_mail' , :environment => 'development',   :output => 'log/autobackup.log'
end

Answer 1

您可以使用 gem 备份。

Backup is a system utility for Linux and Mac OS X, distributed as a RubyGem, that allows you to easily perform backup operations. It provides an elegant DSL in Ruby for modeling your backups. Backup has built-in support for various databases, storage protocols/services, syncers, compressors, encryptors and notifiers which you can mix and match. It was built with modularity, extensibility and simplicity in mind.

Backup 允许您使用 Ruby DSL 对备份作业进行建模:

Backup::Model.new(:my_backup, 'Description for my_backup') do
  # ... Model Components ...
end

:my_backup 符号是模型的触发器，用于执行作业:

$ backup perform --trigger my_backup

它还支持 PostgreSQL、MongoDB、Redis、Riak、SQLite
