Backup, restore or migrate your WordPress website to another host or domain. Schedule backups or run manually. Migrate in minutes. Reliable and easy to use.

== Description ==

<a href="https://updraftplus.com">The UpdraftPlus Backup & Migration Plugin</a> 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.

= Why UpdraftPlus? =

Writing a reliable backup and migration plugin that ‘just works’ consistently across millions of different WordPress deployments is hard. UpdraftPlus is relied upon to do exactly that. We’re trusted and actively deployed on more websites around the world than any other WordPress backup and migration plugin.

UpdraftPlus:

* Backs up, migrates and restores
* Offers a huge number of remote storage locations
* Allows you to schedule backups, so you can ‘set and forget’
* Is comprehensive and easy to use
* Is proven to work on over 3 million sites.

= Are you multilingual? Can you translate? =

Do you want to help people that speak your language to backup, migrate and restore their WordPress websites?

The UpdraftPlus backup, migration and restoration plugin is ready and waiting. The translation process is easy, and web-based – please go here for instructions: https://updraftplus.com/translate/.

Or, if you’re already an expert WordPress translator, just pick out the .pot file from the wp-content/plugins/updraftplus/languages/ directory – if you scan for translatable strings manually, then you need to get these functions: _x(), __(), _e(), _ex(), log_e().

Many thanks to our existing translators.

== Frequently Asked Questions ==

= How do I install the UpdraftPlus backup & migration plugin? =

Here are the installation guidelines from our [YouTube channel](https://www.youtube.com/watch?v=7ReY7Z19h2I) or from [our website](https://updraftplus.com/download/).

= 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](https://updraftplus.com/support/).

Before you get in touch, please ensure that you have read through our [FAQs](https://updraftplus.com/frequently-asked-questions) 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.

== Changelog ==

The [UpdraftPlus backup blog](https://updraftplus.com/news/) is the best place to learn in more detail about any important changes.

* TWEAK: Add function for returning Advanced Tools menu data in a structured format.

= 1.25.1 - 11/Jan/2025 =

* SECURITY: Fix a non-persistent reflected XSS vulnerability due to a missing nonce combined with missing sanitisation. This could allow an attacker, who persuaded you to click a personally-crafted link to your site's dashboard whilst you were logged in, to once run JavaScript code in your dashboard. Thanks to Asaf Mozes for finding and responsibly disclosing this issue.
* FIX: Prevent the restoration from failing when there is a 'sync-xhr=()' permission policy on the response header.
* FIX: Improve the approach of acquiring a suggested region for Amazon AWS S3 if a failure arises during the getBucketLocation() call, particularly when the XML response fails to provide a field for the suggested region - this resolves issues with regions (e.g. us-east-2) which recently changed their response behaviour
* TWEAK: Broaden the support to incorporate the "ap-southeast-4" region of Amazon AWS S3 and additional recently updated regions
* TWEAK: A regression in the paid version update checker to version 4.13.2, resulting in non-appearance of notices concerning subscription status or WP version compatibility.

= 1.24.12 - 23/Dec/2024 =

* FIX: The pre-restoration stage failed to properly address the tables that were to be excluded, which caused a logical error that misread the checked "include all tables not listed" option as an instruction to restore every table
* FIX: Update PHPSecLib library to version 2.0.48 which has the fixes for the "gmp_pow(): base and exponent overflow" on certain PHP versions and could cause backups to fail on the SFTP remote storage
* TWEAK: Complete the review and removal of calls to the unserialize() PHP function allowing class instantiation begun in 1.24.7. (The final removal involved a theoretical security defect, if your development site allowed an attacker to post content to it which you migrated to another site, and which contained customised code that could perform destructive actions which the attacker knew about, prior to you then cloning the site. The result of this removal is that some search-replaces, highly unlikely to be encountered in practice, will be skipped).
* TWEAK: Drop search and replace feature for PHP 5.2 users (to fulfil the preceding item)
* TWEAK: Tweak UpdraftCentral media module to add "has_image_editor" property to each media item
* TWEAK: On the restoration screen in a multisite configuration, the dropdown labeled "which site to restore" was covering other HTML elements, which caused some buttons to be positioned at the bottom instead of at the top
* TWEAK: Avoid deregistering jQuery-UI CSS if already printed by other plugins to prevent compatibility issues
* TWEAK: In the context of database restoration, the execution of LOCK and/or ALTER SQL statements must be avoided for any tables that are part of the "skipped tables" list
* TWEAK: openssl_free_key() is only needed on PHP < 8
* TWEAK: Various coding style changes to comply with "Plugin Check" rules

= 1.24.11 - 15/Nov/2024 =

* TWEAK: Do not request drive.readonly scope on Google Drive connections, due to Google's app permissions review (unannounced and requires us to create a Youtube video for their review process) - this means that (until the review completes) new connections to Google Drive can only access backups created by UpdraftPlus directly, and not backups which you manually upload to Google Drive. This restores the ability to make new connections to Google Drive.
* TWEAK: Adjustment of the UpdraftPlus_S3_Compat class to preserve compatibility with the external UpdraftPlus AWS SDK plugin (https://github.com/DavidAnderson684/updraftplus-aws-sdk).

= 1.24.9 - 14/Nov/2024 =

* FIX: A regression in 1.24.8 when handling restoration of wp-config.php
* TWEAK: The changes in handling of loading text domains in 1.24.8 did not cover most cases
* TWEAK: Introduce the "updraftplus_use_builtin_wpcore_restoration" filter which can be used to restore WP-Core entity using a different WP-Core restoration mechanism especially in a case that the admin-ajax.php file couldn't be deleted during the restoration

= 1.24.8 - 13/Nov/2024 =

* TWEAK: Add descriptions for the 'Clone Package' dropdown when creating a clone.
* TWEAK: Move the "load_plugin_textdomain" call from being called through "plugins_loaded" action to being called via "init" action
* TWEAK: Update the log message to specify that backup files are marked as "processed" when no remote storage is selected, and as "uploaded" when remote storage is selected.
* TWEAK: Some code tidying in the restore class

= 1.24.7 - 04/Nov/2024 =

* TWEAK: Include the .part file extension into the cleanup list, guaranteeing that files associated with this extension are regularly deleted from the backup directory

= 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: A database backup couldn't be taken from WP-Optimize and All-In-One Security (AIOS) (regression)

* TWEAK: Prevent making a nonce available to logged-in users who could not manage UpdraftPlus (this did not give access to any unauthorised actions)

* 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
* TWEAK: Improve the WebDAV storage module API in regard to the way it handles uploading and writing files

* SECURITY: Fixed a failure to sanitise printed URLs properly, leading to a targeted XSS opportunity (if an attacker persuades a logged-in admin to follow a link personally crafted for their site, he may be able to run JavaScript inside the browser - but on our testing, this ability is limited due to the sanitisation that was there - we have not been able to confirm that a payload causing damage is possible).

* SECURITY: Thanks to Marc-Alexandre Montpas of Automattic for this report (CVE: CVE-2022-23303). All versions of UpdraftPlus from March 2019 onwards have contained a vulnerability caused by a missing permissions-level check, allowing untrusted users access to backups. If your site does not have non-admin users, or if your non-admin users are all trusted (and your site does not allow users to sign up themselves), then you are not vulnerable (but we always recommend updating to the latest version in any case). Please see https://updraftplus.com/updraftplus-security-release-1-22-3-2-22-3/ for more details.

* SECURITY: Fix a non-persistent XSS error allowing an attacker to once run JavaScript in your web browser if you clicked on a link crafted personally for you whilst logged into your site (very similar to that fixed in 1.16.65/6). A packaging error meant that this was not properly fixed in the 1.16.67-68 releases.

* FIX: If MySQL performance was very fast on large tables, and if fallback fetch mode was being used (which should not occur on any WordPress core table, but can be triggered on recent Oracle MySQL 8.0 versions), then when increasing rows fetched on large tables, some rows could be unintentionally skipped.
* TWEAK: Oracle MySQL 8.0 from somewhere after 8.0.17 has removed the display width from the response to SHOW CREATE TABLE, resulting in failure (prior to this tweak) to detect a primary key type that can be used with faster fetching
* TWEAK: Use 'wp_mail_failed' action hook to improve logging of email delivery failures caused by a PHPMailer exception

= 1.16.35 - 19/Nov/2020 =

* FEATURE: Backup destinations with conditional logic rules for scheduled backups (Premium)
* FIX: A regression in 1.16.30 meant that the term_relationships table could have rows missing in the backup if mysqldump was not present/used; this meant that items with multiple terms were only having one relationship backed up (e.g. multiple tags being assigned to one post)

* TWEAK: Rename UpdraftCentral's main and listener classes

* TWEAK: Integrate UpdraftPlus and WordPress 5.5 core's automatic update settings
* TWEAK: When a backup resumed, the last successful resumption was incorrectly set as the last successful resumption when an 'alive' event was recorded, rather than a 'useful' one; this deferred some mitigations when there was insufficient progress

= 1.16.31 - 20/Oct/2020 =

* FIX: A regression in 1.16.30 meant that tables with integer primary keys which used signed integers omitted the first row of the table from the backups. This is not common (e.g. it does not affect any core WP tables; most plugins adding tables follow WP core in using unsigned integers for primary keys).

= 1.16.30 - 15/Oct/2020 =

* PERFORMANCE: Where a table has a numerical primary key, extract its data using that index. This results in a substantial performance increase when fetching large tables using PHP. (The filter updraftplus_can_use_primary_key_default can be used to de-activate this behaviour).

= 1.16.25 - 23/May/2020 =

* FIX: Dropbox since 1.16.24 was only deleting one backup files archive out of the set. i.e. Excess archives remained on Dropbox. These have to be deleted manually.

* PERFORMANCE: Force UpdraftClone to use a 100MB split size for better performance (previously intended, but not always working)

* TWEAK: Update class-udrpc to latest (1.4.14) which removes a conflict with other code that may interact with CORS OPTIONS requests
* TWEAK: Escape log lines when sending for display (theoretically an XSS security issue, but to achieve a successful attack, someone would have to first get something malicious into the log file, which is difficult as there are not many places where foreign input can end up in the log file - e.g. hack into Dropbox and cause Dropbox to send you back malicious HTML in an error message - and then be able to persuade you to both take a backup triggering the problem and then view the log file in your WP dashboard)
* TWEAK: Update Google Cloud bucket locations

= 1.13.1 - 09/May/2017 =

* REFACTOR: Completed re-factoring of the remote storage modules, so that now all remote storage code has completed this current stage of re-factoring (more to come in future - laying the foundation for a significant new feature)
* FIX: Added a nonce to the Dropbox deauth link. This is a minor security issue - someone personally targeting you, who knew that you were logged in to your WordPress admin, and who could persuade you to visit a personally-crafted web page, could cause the connection between UpdraftPlus and your Dropbox to be broken. The only impact of this is that the sending of your next backup to Dropbox would fail, and you would be alerted about the need to re-connect.
* FIX: Import settings now handle the new remote storage options format

* FIX: Fix an issue that could occasionally cause corruption of interrupted Dropbox backups. All Dropbox users are recommended to update asap.
* TWEAK: Remove debugging statement inadvertently left in 1.12.36
* TWEAK: Re-factored remote storage handlers via add-ons so that there was a cleaner and more consistent class hierarchy (preparation for future improvements). N.B. If you subsequently downgrade to an older version of UpdraftPlus, you will need to re-enter the settings for some remote storage options.
* TWEAK: List of checksum algorithms run over backups and logged now includes SHA256, and is filterable (SHA1 now considered deprecated)
