WP STAGING – Backup Duplicator & Migration


WP STAGING for WordPress Migration & Cloning

This duplicator, staging and backup plugin can create an exact copy of your entire website in seconds.* Great for staging, backup or development purposes.
(Cloning and Backup time depends on the size of your website)

This clone plugin creates a clone of your website into a subfolder or subdomain (Pro) of your main WordPress installation. The clone includes an entire copy of your database.

Note: For pushing & migrating plugins and theme files to production site, check out the pro edition https://wp-staging.com/

All the time-consumptive database and file cloning operations are done in the background. The plugin even automatically does an entire search & replace of all serialized links and paths.

This staging and backup plugin can clone your website even if it runs on a weak shared hosting server.

WP STAGING can help you to prevent your website from being broken or unavailable because of installing untested plugin updates!


  • WPSTAGING clones the whole production site into a subfolder like example.com/staging-site.
  • 使いやすい! 「新しいステージングサイトを作成」ボタンをクリックして、サイトのクローンを作成します。
  • No Software as a Service – No account needed! All data belong to you only and stay on your server.
  • 巨大なサイトや小さなホスティングサーバーでサーバーがタイムアウトすることはありません。
  • Very fast – Migration and clone process takes only a few seconds or minutes, depending on the website’s size and server I/O power.
  • Use the clone as part of your backup strategy
  • Only administrators can access the clone website. (Login with the same credentials you use on your production site)
  • SEO friendly: The clone website is unavailable to search engines due to a custom login prompt and gets the meta entry no-index.
  • ステージングサイトの管理バーはオレンジ色で、ステージングサイトで作業しているときにはっきりと表示されます。
  • 広範なロギング機能
  • Supports all popular web servers: Apache, Nginx, and Microsoft IIS

  • 新:WordFence、All In One WP Security 、Firewallとの互換性

WP STAGING PRO エディションの追加機能

  • WordPress マルチサイトの移行と複製
  • 別のデータベースとクローン用のカスタムディレクトリを定義する
  • サイトをサブドメインに複製する
  • ステージングサイトにアクセスするための特定のユーザーロールを指定する
  • すべての変更をステージングサイトからライブサイトにコピーします


  1. Use WP STAGING to clone a production website for staging, testing or backup purposes
  2. サイトのバックアップを作成します
  3. テーマのカスタマイズ、設定、新しいプラグインの更新またはインストール
  4. ステージングサイトですべてをテストし、元のサイトのバックアップを保持します
  5. すべてがステージングサイトで機能する場合は、移行を開始し、すべての変更を本番サイトにコピーします。


Plugin updates and theme customizations should be tested on a staging platform first before they are done on your production website.
It’s recommended having the staging platform on the same server where the production website is located to use the same hardware and software environment for your test website and to catch all possible errors during testing.

これにより、予期しないエラーをスローしたり、サイトの読み込みを妨げたりすることなく、変更が運用サイトで機能するようになります。 「WordPress 空白ページエラー」として知られています。

Testing a plugin update before installing it in a production environment isn´t done very often by most users because existing staging solutions are too complex and need a lot of time to create a
an up-to-date copy of your website.

これは、WordPress のインストールが古くなっていて、まったく更新されておらず安全でないことが多い主な理由の1つです。

It’s time to change this, so use “WP STAGING” for cloning, backup and migration of WordPress websites

テストやバックアップの目的で、xampp / lampp のようなローカルのWordPress ステージングシステムを使用できませんか?

You can test your website locally but if your local hardware and software environment is not a 100% exact clone of your production server there is NO guarantee that every aspect of your local copy is working on your production website exactly as you expect it.
There are some obvious things like differences in the config of PHP and the server you are running but even such non-obvious settings like the amount of RAM or the CPU performance can lead to unexpected results on your production website.
There are dozens of other possible cause of failure which can not be handled well when you are testing your changes on a local platform only without creating a backup staging site.

This is were WP STAGING jumps in… Site cloning, backup and staging site creation simplified!


If you want to migrate your local database to an already existing production site you can use a tool like WP Migrate DB.
WP STAGING is intended for creating a staging site with latest data from your production site or creating a backup of it. So it goes the opposite way of WP Migrate DB.
Both tools are excellent cooperating each other.

Duplicator のようなプラグインと比較して利点は何ですか?

I really like the Duplicator plugin. It is a great tool for migrating from a development site to production one or from production site to development one and a good tool to create a backup of your WordPress website.
The downside is that before you can even create an export or backup file with Duplicator a lot of adjustments, manually interventions and requirements are needed before you can start the backup process.
Duplicator also needs some skills to be able to create a backup and development/staging site, where WP STAGING does not need more than a click from you.
Duplicator is best placed to be a tool for first-time creation of your production site. This is something where it is very handy and powerful.

ローカルまたはWebでホストされた開発サイトを作成し、このサイトを初めて本番ドメインに移行する必要がある場合は、Duplicator プラグインを使用して何も問題はありません。
テスト環境で投稿、更新されたプラグイン、テーマデータ、スタイルなどの最新の本番データが必要な場合、または何かをテストする前にクイックバックアップを作成する場合は、代わりに WP STAGING を使用することをお勧めします。


This plugin has been created in thousands of hours and works even with the smallest shared web hosting package.
We also use enterprise level approved testing coding structures to make sure that the plugin runs rock solid on your system.
If you are a developer you will probably like to hear that we use Codeception and PHPUnit for our software.

As there are infinite numbers of possible server constellations it still might happen that something does not work for you 100%. In that case,
please open a support request and describe your issue.

  • What is the Difference between WP STAGING and a Regular Backup Plugin?
    You may have heard about other popular backup plugins like BackWPUp, BackupWordPress, Simple Backup, WordPress Backup to Dropbox or similar WordPress backup plugins and now wonder about the difference between WP STAGING and those backup tools.
    Other backup plugins usually create a backup of your WordPress filesystem and a database backup which you can use to restore your website in case it became corrupted or you want to go back in time to a previous state.
    The backup files are compressed and can not be executed directly. WP STAGING on the other hand creates a full backup of the whole file system and the database in a working state that you can open like your original production website.

Even though WP STAGING comes with some backup capabilities it’s main purpose is to create a clone of your website which you can work on. It harmonies very well with all the mentioned backup plugins above and we recommend that you use it in conjunction with these backup plugins.

Note, that some free backup plugins are not able to support custom tables. (For instance the free version of Updraft plus backup plugin). In that case, your backup plugin is not able to create a backup of your staging site when it is executed on the production site.
The reason is that the tables created by WP STAGING are kind of custom tables beginning with another table prefix.
To bypass this limitation and to be able to create a backup of your staging site, you can setup your backup plugin on the staging site and create the backup from that location. This works well with every available WordPress backup plugin.

  • I can not log in to the staging / backup site
    If you are using a security plugin like All In One WP Security & Firewall you need to install the latest version of WP STAGING to access your cloned backup site.
    Go to WP STAGING > Settings and add the slug to the custom login page which you set up in All In One WP Security & Firewall plugin.


Anytime there is a issue that comes up outside of the FAQs (and that is very rare) They are right on top of it and take care of things immediately! I've been using the plugin for years on many sites, and have never been discouraged. It's saved me hundreds of hours in development and in the testing of updates before updating live sites. It's my #1 must have plugin!
By creating a sandbox environment, this saved me a lot of site outages that used to occur while updating plugins. Great plugin.
Works very well. Managed to redesign site with very little trouble as staging meant I had tested any conflicts with other areas of the site. Would recommend
I really like the ease of use the plugin gives you. I love that I can make all my changes and edits, update my main site with no problem\. This plugin takes the fear out of messing up your live site. An absolute must-have in my opinion. Thank you so much, guys!
