All-in-One WP Migration

Most-installed backup and migration plugin, with paid unlimited restores

Overview

All-in-One WP Migration and Backup is developed by ServMask. First listed on WordPress.org on 7 January 2014, it had more than five million active installations in November 2026, the most of any backup plugin, with version 7.113 released on 27 October 2026.[1]

The plugin exports an entire site, including database, media, themes and plugins, into a single .wpress archive and imports it through a drag-and-drop screen on the destination site. It processes data in 512 KB chunks to suit resource-limited hosting, supports PHP 5.3 to 8.4, and can migrate between MySQL, MariaDB and SQLite databases, with find-and-replace and selective export for developers.[1] ServMask states plainly that the free plugin backs up and exports sites of any size, but restoring a large backup for free depends on the host’s upload limit; the paid Unlimited Extension adds one-click restore from the Backups page and bypasses PHP upload, timeout and memory limits.[1][2] The plugin page also claims use by “over 60 million websites” and by organisations such as NASA and Harvard; these are vendor claims.[1] Scheduled backups to cloud storage require further paid extensions.
