What is the WordPress Duplicator plugin?

Duplicator is a WordPress plugin that moves a site between hosts or domains - this includes all plugins, themes, custom content and even the WordPress core files so you get an exact copy of your site. The product also provides backup capability.

The process for moving a site is easy:

  1. Bundle up your site into an 'install package' (a .zip and a .php file)
  2. Copy the two files to a new server
  3. Point your browser to the .php file and follow the simple directions to install the site

With Duplicator Pro you can enhance your experience with a much more powerful tool-set. Checkout the full comparison page for more details.

How does Duplicator work?

Phase 1: Package Creation

The plugin will backup all of your selected files and database tables (that you don't filter/exclude). The Duplicator puts all your selected WordPress files and a scripted copy of your database into a single zip file called an archive and builds an installer file. The installer and archive files are referred to as a package. You can then download the package files to a different location where you can re-install your site.

Phase 2: Site Install

At install-time the following actions happen:
  • Archive Extraction. All WordPress files are extracted from the archive. This includes archive metadata and the database script.
  • Database Creation. The database script is executed to restore the original data in the new database.
  • Database Scrubbing. Every table is processed and the old URLs are replaced with the new ones. Various methods of storage are considered (PHP serialization, JSON, Base64, etc...)
  • Optional Overhead. Duplicator Pro has additional logic that runs such as multisite manipulation.
  • Config File Scrubbing. The wp-config.php is scrubbed for updates to WP defined variables
  • .htaccess set. The .htaccess file is reset for the new location
Will Duplicator work with all my themes and plugins?
In 99% of most cases it will work with your theme and your plugins. However there can be issues at install type where data was not able to port correctly. This is where you will need to read the final report on step 3 of the installer and validate the options that the plugin could not update. If you run into any errors or warnings please read the section directly below.
What is the package size limit?
On 64 bit versions of PHP there is effectively no limit on .zip file size, however the maximum file size supported on 32-bit PHP is 2.1GB. Note that most hosts support 64 bit PHP.

CPU and memory constraints imposed by your host may also limit zip file size by cutting off the build early. Because of this, we developed the DupArchive format to get around these host limitations. When using the DupArchive engine, Duplicator Lite is capable of bundling sites up to 500MB in size, while Duplicator Pro has no size limit outside of the limit imposed by your PHP architecture.
How does Pro differ from the Lite version?
A comparison list of professional vs free can be found on the comparison page. While Pro will continually be improving and adding features, the Lite (free) version of the plugin is not expected to have any new major features except for bug fixes and smaller tweaks. For larger sites Pro also supports shell_exec and Ajax call backs for PHP ZipArchive which allow for larger packages upto 2GB on most servers.

How does Duplicator handle multisite (MU) support?
Duplicator Lite: Does not support multisite.
Duplicator Pro: Includes the following multisite duplication modes.

1. Full Network Duplication Since 2.0 | Requires "Duplicator Pro Personal" or above
This allows users to copy/move your entire Multisite installation, rather than backing up or moving individual subsites within the network. For example, if you had a 10 subsite multisite setup, all 10 sites could be moved and restored as a new Multisite installation in one shot to a new location. [User Guide]

2. Subsite ❯ Standalone Since 3.0 | Requires "Duplicator Pro Business or Gold"
This allows users to install an individual subsite within a Multisite network as a standalone site. For example, if you had a 10 subsite WordPress multisite, you can select just one of those sites to restore to be a new standalone site. This process could optionally be repeated 9 more times on different sites to create a total of 10 individual websites from the single Multisite install. [User Guide]

3. Standalone ❯ Subsite Since 4.0.3 | Requires "Duplicator Pro Business or Gold"
This allows users to take a full standalone WordPress site and integrate it into a Multisite network. For example you may have dozens of WordPress sites that you manage and you want to pull them all together into one Multisite network for easier management. [User Guide]

4. Subsite ❯ Subsite [Different Network] Since 4.0.3 | Requires "Duplicator Pro Business or Gold"
This allows users to take a Multi-site subsite and add it into a different Multisite network as a subsite. For example you may have several subsites of a Multisite network that you to move into a separate Multisite network but only want to move specific subsites. [User Guide]

5. Subsite ❯ Subsite [Same Network] Since 4.0.3 | Requires "Duplicator Pro Business or Gold"
This allows users to take a Multi-site subsite and add it into a different Multisite network as a subsite. For example you may have several subsites of a Multisite network that you to move into a separate Multisite network but only want to move specific subsites. [User Guide]

NOTICE: Options 3-5 were released in Duplicator Pro 4.0.3 as beta. These options only support adding new standalone and subsites into an existing Network. Support for overwriting existing sites is available in 4.0.4 and later.

Currently adding a subsite requires the install process to be run for each subsite. So if you currently have 20 subsites you want to move into another multisite network the installer will need to be run 20 separate times. In future version we plan to have this process narrowed down to just one installer run.

Notice: Upon install you'll observe that the Duplicator Pro menu appears at the Network level rather than the Admin level as is the case when installing on a standalone site.
Duplicator Pro currently supports the scenarios above for Multisite, however we are continually working to improve the product. For a list of upcoming features and possible time-lines please visit the Duplicator Pro Roadmap which discusses additional Multisite features.
Is my server/host compatible with the Duplicator Pro?
Standard Hosts
Duplicator Pro works on 99% of all servers, however if your host does not support the plugin for one reason or another we will issue you a prompt refund. All we ask is that you provide the name of the hosting provider that does not support the plugin.

The server requirements for Duplicator are: Note: 99% of all hosting companies will meet these basic requirements. For a full break-down of setup recommendations see the Duplicator Pro recommended hosts page.

Managed Hosts
The Lite version of Duplicator does not officially support managed hosts at this time. There is currently a unification project underway to merge both the Pro and Free code lines so that the Free product can also take advantage of these features. The unification project is slated for late 2022 or 2023, until that time only support for managed hosting will reside in the Pro product version 4.0.0 and above.

Duplicator Pro does currently supports the managed hosts below. Managed WordPress Hosting is a tailor-made and optimized type of web hosting that is specifically designed to support WordPress sites on a companies servers. These types of configuration do not typically follow the standard host models and require additional logic to support.
Note: Managed hosting has a much higher churn rate on server settings and updated environments. These changes can affect how the product interacts with each managed host. In the event you run into issues with any of the managed hosts, please contact us with your issue and we will work to help you finalize your migration and update the product if needed.

Licensing Pro Only

How do site licenses work?


When you purchase a product, it comes with one license key that can be activated on 3, 15, or unlimited WordPress websites at a time, depending on the product (Personal 3 | Freelancer 15 | Business/Gold unlimited).

Personal Example:
If you bought the Personal product with 3 licenses, then you can use the plugin on 3 WordPress websites at a time. If you uninstall the plugin from one site you can easily install it on another and still retain your license count.

Freelancer Example:
If you purchase the Freelancer plan, you can install the plugin on 15 sites. If you want to install a 16th site you can uninstall on one of your existing sites and move the license to another or upgrade to a higher level plan before installing on the new site.

Licenses for Duplicator Pro Business and Gold are unlimited. Please note that these licenses are assigned in increments 500 at a time. For more details see the section below "Unlimited Overview".

Multisite Example:
If you have a WordPress multisite, then the entire site including all subsites will consume only 1 license. For example, if you have a multisite with 100 subsites then only 1 license key is needed for that entire multisite - subsites do not require a key. Please note that only the Business/Gold products have extended multisite support.


  • In Plugin: You can easily deactivate a license by going to WordPress Admin ❯ Duplicator Pro ❯ Settings ❯ Licensing tab ❯ "Deactivate" button.
  • Delete Plugin: When a user deactivates and deletes the plugin then the license will also be deactivated from the Snapcreek server.
  • Dashboard: In the event you purge a site before deactivating the license or deleting the plugin you can login to the dashboard and deactivate the license that way as well.

Unlimited Overview

Users that purchase either Business or Gold versions of Duplicator Pro have access to unlimited licenses. In order to make sure licenses are not abused or present problems were they to get "into the wild", we increment them in batches of 500. If you happen to reach your limit please reach out to us via a help ticket and we will increase your lot size.


You can upgrade to the Freelancer, Business or Gold package via the to get more licenses. Upgrades can happen at anytime and are a separate process from renewing. Please visit the upgrade & renewal section for more details.

How can I upgrade my license/product?
License upgrades are seamless and easy to apply. The cost of upgrade is equal to the price of the new license minus the price of your existing license. For example: if you bought Duplicator Pro Personal for $69 and want to upgrade to Freelancer $89 then your upgrade cast would be $20.

Renewals vs Upgrades: If you are in the process of renewing and upgrading at the same time its best to renew first then upgrade for the best price. The renewal date and upgrade date are two separate events. For example if you purchased on January 1st 2020, then upgraded on July 1st 2020, your renewal date would still be January 1st, 2021.

Will Duplicator Pro resolve "Build Interrupt" errors found in the Lite version?
In many cases the answer is yes, however it really depends on your servers capabilities and the overall size of your package. If your trying to backup a 10GB site on a budget host the chances will be much lower that the servers specs can handle it, without adding directory exclusion filters.

However if your using a higher end server or VPS where you have more flexibility and control of the servers settings then we have seen large packages over 8GB build without issues.

Remember we do have a full 30 day money-back guarantee should the product not meet your needs.
Can I save my website copy to my own server using your system?
Yes! Using the default storage, the website will be backed up to a specific location on your site. In Duplicator Lite this will always be in a folder titled wp-snapshots. In Pro this value is dynamic and can be changed to user definable areas of the same server for storage.
How frequently can I schedule a backup for a given site?
This feature is only available in Pro. Schedules can be setup as frequently as you want. Scheduling in Duplicator is very straight forward. No complicated configuration screens. Duplicator supports the creation of multiple schedules by either Day, Week or Month. If you would like to backup your site several times per day you can do this by creating multiple daily schedules.
Duplicator Pro lets you change more WP-Config settings than Duplicator. What are these settings?
The Duplicator Pro Installer allows you to set the following in the destination site's wp-config.php file:

Posts / Pages
  • Theme Editor Enable/Disable
  • Autosave Interval
  • Post Revisions
  • SSL Enforce on Admin
  • Generate New Unique SALTS and Authentication Keys
