UpdraftPlus: WP Backup & Migration Plugin


The UpdraftPlus Backup & Migration Plugin is trusted by the WordPress community to backup, restore and migrate their WordPress websites. UpdraftPlus is actively installed on more than 3 million websites around the world.

Backup with UpdraftPlus

UpdraftPlus is the world’s highest ranking and most popular scheduled backup and migration plugin. Backup to your preferred storage location and restore in just three clicks.

Backup to Dropbox, Google Drive, Amazon S3 (or compatible), Rackspace Cloud, FTP, DreamObjects, Openstack Swift or email.

The paid version also allows you to backup to Microsoft OneDrive, Microsoft Azure, Google Cloud, Backblaze B2, SFTP, SCP, pCloud, WebDAV or UpdraftVault, our integrated storage option for UpdraftPlus.

Backup manually or schedule to run every 2, 4, 8 or 12 hours, daily, weekly, monthly or fortnightly.

Restore with UpdraftPlus

Your WordPress website is vulnerable. Your site may get hacked. Something could go wrong with an update or your server could crash. You might need to reverse a change made or a mistake caused by human error.

Whatever the reason, you can restore your WordPress website in just a few clicks with UpdraftPlus. Choose which components to restore (e.g. plugins, themes, database etc.), click again to restore, then click again to return to the main screen.

Migrate with UpdraftPlus

It’s easy to migrate your WordPress website to another web host, server or domain with this free version of UpdraftPlus.

To migrate, simply download your database, plugins, themes etc. from the source site, then upload them into your destination site.

When migrating, a built-in search-and-replace engine identifies old strings and replaces these to reflect the new location. UpdraftPlus saves you time and reduces the risk of broken links or missing files associated with manual migrations.

How do I install the UpdraftPlus backup & migration plugin?

Here are the installation guidelines from our YouTube channel or from our website.

What if I have a problem / need support ?

If you’re struggling to backup, migrate or restore there’s help available.

Search existing topics on the WordPress support forum or post a new one. Our support and development teams check and respond to queries everyday.

UpdraftPlus Premium customers can log a ticket directly with our support and development teams via the UpdraftPlus support hub.

Before you get in touch, please ensure that you have read through our <a href=https://updraftplus.com/frequently-asked-questions/ »>FAQs and that you’ve updated to the latest release of our plugin.

It helps greatly if you can include the backup log and as much other information as possible in your report, for example the PHP version, your website, the error description, how you got to the page that caused it, any other relevant plugins you have installed, plus any other information that might be of use.

To find the backup log: there are links to download the logs on the UpdraftPlus settings page in the plugin – or you may be emailed it. Failing that, FTP into the directory wp-content/updraft and look for it there.

If you know how, please send your PHP error logs – just the few lines that appear when you run a backup, often the file called error_log, possibly in your wp-admin directory which you can check via FTP. If you’re a programmer that can debug and send a patch, that’s even better.

When it comes to migration, what does the premium plugin do that the free plugin can’t?

Migrating in the free plugin involves downloading the backups from the source site then uploading these to the destination site.

To find the backup log: there are links to download the logs on the UpdraftPlus settings page- or you may be emailed it. Failing that, FTP into the directory wp-content/updraft and look for it there.

Both free and Premium plugins include a built-in search-and-replace engine to replace old strings with the new location.

If migration is all you require, and for simple single site migrations the free plugin will likely be enough to meet your needs. If you have additional needs around backups e.g. the ability to backup before updates, if you require more remote storage locations or if you have a WordPress multisite then we recommend UpdraftPlus Premium for the additional benefits that it brings.

UpdraftPlus runs out of time when it’s trying to backup, after I have left it for some time to give it a good chance. What can I do?

This problem is probably caused by your account being starved of resources by your (cheap) web host provider. This is far from ideal; although UpdraftPlus supports resuming backup runs right from the beginning to avoid everything having to be done at once, it has its limits. The best thing is to choose a more reputable web host. Failing this, try going into the “Expert settings” and reducing the size at which zip files are split. UpdraftPlus is known to successfully backup websites that run into the multiple-gigabytes on web servers that are not resource-starved.

Hello. I use UpdraftPlus with Google Drive as my remote storage. While running my site, I changed the theme, and everything went wrong. I was worried, but then I remembered UpdraftPlus and tried to restore it. It was restored very easily. Now, I believe that as long as you have good backups, you can solve any problem. This is really the best plugin. Five stars are not enough. I send a million stars. Thank you.

I use UpdraftPlus with Google Drive as remote storage. It’s one of the first plugins I install on any new site. As we all know one incompatible plugin activation can take down weeks of work. UpdraftPlus is easy to use and if something happens and you need to restore, it only takes a few clicks to get your site back. As with any backup plugin, your results depend on how regularly the backup process is initiated.

Such a tool proves it self especially when you need to restore. And this one  proves it self to me.

1.23.11 – 03/Nov/2023

  • SECURITY: Fix a vulnerability which could, if you had Google Drive storage enabled, and if an attacker targetted a logged-in administrator on your site and persuaded them to access a specific URL that the attacker creates, add the attacker’s own Google Drive account to the saved storage methods.

1.23.4 – 16/May/2023

  • SECURITY: Fixed a missing nonce combined with a URL sanitisation failure, which could lead to a targeted XSS opportunity (if an attacker persuades a logged-in administrator to both re-authorise their connection to a remote storage (e.g. Dropbox) and then to follow a link personally crafted for their site before re-authorising whilst logged in, he can then store a fixed JavaScript payload in the WP admin area (they would need a further route to use that ability to cause any damage). Because of the need for the administrator to co-operate in multiple steps, this attack is very unlikely (but you should of course still update).
  • FIX: DigitalOcean S3-compatible storage does not work with disabled SSL entirely where possible settings.
  • FIX: If there was an error or network connectivity issue on first attempt of uploading a plugin/theme file, then the second attempt of uploading the same file would make the file become corrupted thus resulting in installation failure.
  • COMPATIBILITY: Suppress htmlspecialchars deprecation warnings on PHP 8.1
  • COMPATIBILITY: Suppress some PHP 8.2 deprecation notices from use of ${} style variables, and others from use of dynamic properties
  • TWEAK: Handle web hosting company setup that disabled pclose() but not popen()
  • TWEAK: All HTTP requests to the Google Drive API now, by default, forces to use HTTP/1.1 version. Also, a constant named UPDRAFTPLUS_GDRIVE_CURL_HTTP_VERSION can be set in the wp-config.php file to change the default HTTP version to another preferred version
  • TWEAK: Improve ‘move’ and ‘copy’ filesystem functions in restoring directories containing files to a different mount point/partition than where they reside
  • TWEAK: Improve files pruning mechanism, by not repeating already-done ones when resuming deletions
  • TWEAK: Improve the Handlebars templates of the Google Drive, Dropbox and UpdraftVault remote storage modules by taking PHP code out of them
  • TWEAK: Improve widget layout when decrypting a backup

  • TWEAK: Add multisite subsites header information to the database backup file that will be used for converting a network subsite to a standalone normal WordPress site
  • TWEAK: Add the UpdraftPlus plugin slug header to the database backup file

  • TWEAK: Added the « non-core » word to the WordPress database tables excluded warning.
  • TWEAK: Remove WordPress core tables from the non-core WordPress database tables excluded list in restoration step 2
  • TWEAK: When migrating the www site, the search replace will be performed in database tables on the non-www domain too, and vice versa

1.23.3 – 16/Mar/2023

  • SECURITY: This release fixes an important security defect – please update. Full details: https://updraftplus.com/updraftplus-1-23-3-2-23-3-important-security-release/. Sites are affected if there are WordPress users (i.e. people who can login) who can reach the back-end (i.e. wp-admin) dashboard (but we recommend everyone updates in any case).

1.23.2 – 15/Mar/2023

  • FIX: Automatic backups before updating a plugin, theme, or WP core were not working (regression in 1.23.1)
  • FIX: A database backup couldn’t be taken from WP-Optimize and All-In-One Security (AIOS) (regression)
  • TWEAK: Add a user capabilities check when downloading a backup (this is not believed to have any security implications, as the download operation already requires knowledge of a further nonce that there is no mechanism for a non-administrator to obtain).

  • FIX: Sometimes the « delete old directories » notice displayed even though the actual -old directory didn’t exist

On sites running on end-of-lifed PHP versions (<8.0) it was possible to read the beginning of the log file, causing an unintended information disclosure about the server environment, e.g. Apache version, PHP version and available memory (but current PHP versions are not vulnerable).
  • TWEAK: Use nonce when starting a new restoration and strengthen the continuation process to prevent direct access that has the potential of being file and/or log abuse
