ruby-on-rails – 将DB备份在rails 4中[已关闭]

有一个宝石db2fog,但它只适用于Rails 3.
有没有适合在Rails 4中进行数据库备份？

解决方法

看看 Backup宝石.它提供了一组非常好的功能,如：

>数据库支持：MySQL,MongoDB,PostgreSQL,Redis …
>压缩
>加密
>存储：Amazon S3,本地,RSync,Dropbox …
>通知：电子邮件,Twitter,Hipchat …
>友好DSL

该插件完全独立于Rails,因此您可以将其用于其他应用程序.

备份模型示例(MySQL,Amazon,Gzip和电子邮件通知)：

Model.new(:my_backup,'My backup description') do
  database MySQL do |db|
    db.name     = "database_name"
    db.username = "username"
    db.password = "pass"
    db.host     = "localhost"
    db.port     = 3306
  end

  store_with S3 do |s3|
    s3.access_key_id     = "access_key_id"
    s3.secret_access_key = "secret_access_key"
    s3.bucket            = "bucket_name"
    s3.path              = "path/to/your/backups"
  end

  compress_with Gzip

  notify_by Mail do |mail|
    mail.on_success     = true
    mail.on_warning     = true
    mail.on_failure     = true

    mail.from           = "[email protected]"
    mail.to             = "[email protected]"
    mail.address        = "smtp.gmail.com"
    mail.port           = 587
    mail.domain         = "your.host.name"
    mail.user_name      = "[email protected]"
    mail.password       = "pass"
    mail.authentication = "plain"
  end
end

执行备份：

$backup perform --trigger my_backup

安排您的备份与cron工作(例如,每当gem),你将实现一个简单而有效的解决方案：

every 1.day,:at => '1:00 am' do
  command "backup perform --trigger my_backup"
end

希望这可以帮助你.
