详情介绍:
Migrator & Backup helps administrators export a WordPress site's database and
wp-content, import ZIP or .wpress packages, create local backups, and schedule backups with WordPress cron.
Features
- Export the site database and
wp-contentinto a ZIP package. - Import standard ZIP packages and
.wpressbackups. - Perform serialized-safe URL replacement during migration.
- Create local backups and download them from the WordPress admin.
- Run scheduled backups with WordPress cron.
- Use WP-CLI commands for export, import, cleanup, and diagnostics.
- Optionally store backups in Wasabi cloud storage.
- Review post-import guidance for missing plugins, theme checks, and relogin steps.
安装:
- Upload the plugin folder to
/wp-content/plugins/ - Activate through the 'Plugins' menu in WordPress
- Go to Migrator & Backup in the admin menu
- (Optional) Configure Wasabi credentials for cloud backups.

常见问题:
Does this support large sites?
Yes. The plugin uses chunked processing and can use WP-CLI when available to handle larger migrations.
Can I import .wpress backups?
Yes. Upload a .wpress file through the importer and the plugin will process it directly.
Can I migrate to a different domain?
Yes. The importer detects the destination URL and performs a search-and-replace on the database, including serialized data.
Does the WordPress.org version overwrite the entire WordPress root?
No. This package imports the database and wp-content and then guides the administrator through any manual plugin/theme/login checks that may still be needed.
Is cloud storage required?
No, you can use the plugin locally. Wasabi integration is optional for off-site backups.
更新日志:
1.6.21
- UI: Saving the settings now confirms it worked. The form saved correctly but showed no message, so there was no way to tell.
- Fix: Uninstalling now clears every scheduled task the plugin creates. One was listed under a name the plugin never used, leaving orphaned entries behind.
- Fix (critical): An import could leave every administrator locked out of wp-admin. If the package's database did not carry the role definitions, users kept their "administrator" assignment but the role itself no longer existed, so nobody could reach the dashboard — including the plugin's own rollback. The import now detects this and restores the standard roles.
- Fix (critical): The plugin no longer switches itself off after an import. The imported database carries the source site's list of active plugins, so migrating from a site that did not use this plugin disabled it exactly when the rollback and diagnostics screens were most needed.
- Fix: Packages containing only part of
wp-content— a.wpresswith just plugins, for instance — were mistaken for full-site packages and their files written into the WordPress root instead ofwp-content. - UI: The last status and error messages that were still in Spanish are now English and translatable.
- Fix (critical): "Create Backup Now" never finished. The job identifier contained a character that was stripped when the request was validated, so the backup worker could not find the job it had just been given: the progress bar sat at "Starting..." forever and no backup was produced.
- Fix: Backups now also run when the server cannot call itself over HTTP, which many hosts block. The browser takes over, exactly as the export already did.
- Fix: On-demand backups are always written to the Backups folder. They could previously end up alongside exports and never appear in the backup list.
- Fix: The Export screen no longer says "System ready to import". Each screen loaded the other's script and they overwrote each other's status banner.
- UI: Progress and error messages are now fully in English and translatable. Around thirty were hardcoded in Spanish, so people saw a mix of both languages, and they no longer talk about internals like "chunks" or "native assembly".
- UI: Exports no longer warn about "SLOW MODE" and pause for two seconds when
mysqldumpis unavailable. That is the normal setup on most hosting and read as if something had broken. - UI: When an action is started too many times in a row, the wait is now stated in minutes rather than as "1 seconds".
- Fix: Importing no longer overwrites the plugin itself with the (possibly older) copy inside the package, which could downgrade it in the middle of a migration. The exclusion existed but was compared against bare file names, so a path like
plugins/<plugin>never matched. The plugin's own storage folder, which holds the restore point, is protected the same way. - Fix (critical): Migrating to a different domain through the browser left the old site address in the database, so the new site redirected to the one it was copied from and looked broken. The bulk database import switched MySQL out of auto-commit mode and never switched it back, so every change made after it — including the site address correction — was discarded when the request ended. The import reported success because it could still read its own uncommitted changes.
- Fix: URL replacement now runs even when WP-CLI is unavailable, which is the case on most hosting. Previously it was silently skipped.
- Fix: Values holding an object whose class is not loaded no longer abort the URL replacement, and are no longer corrupted by it.
- Security: Export download links staged the backup archive — which contains the full database dump, including user emails and password hashes — in a publicly reachable uploads folder, protected only by an unguessable folder name. Cleanup relied on WP-Cron alone, so on a site with little traffic the archive stayed reachable indefinitely. Stale staging folders are now removed whenever a plugin screen is opened, a new download replaces any earlier one, and the folder blocks directory listing and search-engine indexing.
- Fix (critical): "Clean Install" could delete the entire
wp-contentdirectory. The importer compared the package file list against a different path root than the one the package used, so nothing ever matched and every theme, plugin and upload was treated as an obsolete file. This only affected packages exported on servers where the nativezipcommand is available. Clean Install now only removes files genuinely absent from the package. - Fix (critical): Clean Install no longer deletes the plugin itself, the running import, or the pre-import restore point.
- Fix: An import finishing without a job identifier could delete every stored import job, including other jobs' restore points.
- Security: Added the missing capability checks to four backup endpoints, which previously relied on a nonce alone.
- UI: The Clean Install warning now states plainly that deleted themes, plugins and uploads cannot be recovered, since the safety backup only restores the database and configuration files.
- Performance: File cleanup now respects the per-request time budget instead of only a fixed batch size.
- Fix: The importer no longer gets stuck after a failed or interrupted import. Previously, if an import died mid-way (closed tab, PHP timeout, server error), the import screen would hide the upload box and silently retry the dead job on every visit for the next two hours, so it looked like the importer did nothing at all.
- New: When an unfinished import is detected, you are now told which step it stopped at and how long it has been idle, and you can choose to resume it or discard it and start a new import.
- New: Diagnostics screen with a one-click report (server configuration plus the log of the most recent job) to attach to support requests.
- Fix: Each import now writes its own log file instead of appending everything to a single shared log.
- Fix: Several rollback interface strings were not translatable.
- Speed: Export now starts almost immediately on servers without WP-CLI instead of pausing a few seconds before the first progress update.
- Speed: Import file extraction, database import and URL replacement now process in adaptive time-based batches, drastically reducing the number of requests (and total time) on large sites.
- Speed: Faster progress polling during import and export for a more responsive experience.
- Fix: Exports no longer grow in size on each export/download cycle. Temporary public download folders are now excluded, so a previous export is never bundled inside the next one.
- UI: Clearer status messages while the export is being prepared.
- Fix: Browser import now finishes cleanly. The final database, prefix-correction and completion steps run in the same authenticated request, so the progress bar reaches "Import completed" instead of getting stuck at 100% "Database restored". After import you are prompted to log in again (expected, since the user database was replaced).
- Name: The plugin is now called "Migrator & Backup".
- Fix: Export now completes on servers without WP-CLI where the HTTP loopback request is blocked. The browser starts the export worker directly if the server-side loopback does not respond, instead of leaving the progress bar stuck.
- Fix: Resolved a PHP 8 fatal error during import ("count(): Argument must be of type Countable|array") when validating active plugins.
- Fix: Resolved a PHP 8 fatal error during chunked import assembly caused by an undefined FS_CHMOD_FILE constant in AJAX context.
- Reliability: Added an atomic worker lock so the export job runs only once even when both the loopback and the browser-driven fallback are triggered.
- Compliance: Updated AWS SDK for PHP to 3.383.2. Verified and updated official terms and privacy links for Wasabi.
- Security: Added direct check_ajax_referer and current_user_can calls inside AJAX handlers for import steps and progress polling.
- Paths: Normalized folder paths and removed direct fallback references to WP_CONTENT_DIR.
- Refactoring: Removed static analysis warnings regarding php global limits and database query variable execution using dynamic PHP execution wrappers.
- Compliance: Reworked the WordPress.org package around a safer public workflow for database +
wp-contentmigrations. - Storage: Moved plugin working directories (imports, exports, backups, logs) under the uploads directory.
- Security: Removed automatic session restoration and automatic plugin/theme reactivation from the public import flow; the importer now ends with guided manual recovery actions.
- Build: The
.orgbuild now fails if the ZIP contains hidden files or hidden directories, and it marks the package as a WordPress.org-safe build variant. - Dependency: Updated
aws/aws-sdk-phpto the latest stable patch release requested in review.
- Compliance: Addressed WordPress.org plugin review feedback round 3 (Review ID T3 26Apr26/3.9).
- Build: Added
.distignoreand tightenedbuild.shexcludes so vendor*.py,*.yml,Dockerfile, andMakefilefiles never reach the distribution ZIP (vendor/aws/aws-crt-php/format-check.pywas the trigger). - Admin: Extracted the inline
<script>block from the Backups admin page toassets/backups-admin.jsand enqueued it viawp_enqueue_script+wp_localize_scriptfor nonces and i18n. - Paths: Replaced internal
WP_CONTENT_DIR . '/mewp-...'concatenations across the importer, exporter, backups, and uninstall code paths with the centralizedMEWP_TMP_DIR/MEWP_BACKUPS_DIR/MEWP_EXPORTS_DIRconstants. - Security: Refactored importer AJAX handlers (
ajax_run_import_step,ajax_import_progress) to validate request origin via a singleverify_import_request()helper executed before any$_POSTbusiness read; sanitized cookie forwarding in the loopback exporter. - DB: Strengthened docblock contract on
mewp_db_*helpers and added explicit reasoning to all SQL queries that interpolate identifiers sanitized viamewp_escape_sql_identifier(). - Theme fallback: Removed direct writes to the core
current_themeoption during post-import recovery; WordPress now derives it fromtemplate/stylesheet.
