## Description

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-content` into a ZIP package.
 * Import standard ZIP packages and `.wpress` backups.
 * 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.

Developed and maintained by [IDEIWEB](https://ideiweb.com/), a web development studio.

### External services

#### Wasabi cloud storage

This plugin can connect to Wasabi so you can upload backups to your own Wasabi bucket
and download them later.

When cloud storage is enabled, the plugin sends the backup file, the configured 
bucket and region, and the Wasabi credentials you entered in the plugin settings
to Wasabi’s API endpoints over HTTPS.

Wasabi Terms of Service: https://wasabi.com/legal/terms-of-use/
 Wasabi Privacy

This WordPress.org package does not require any external service by default. If 
Wasabi is left disabled, the plugin works locally and does not connect to Wasabi.

## Installation

 1. Upload the plugin folder to `/wp-content/plugins/`
 2. Activate through the ‘Plugins’ menu in WordPress
 3. Go to **Migrator & Backup** in the admin menu
 4. (Optional) Configure Wasabi credentials for cloud backups.

## FAQ

### 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.

## Changelog

#### 1.6.8

 * **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.

#### 1.6.7

 * **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).

#### 1.6.6

 * **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.

#### 1.6.5

 * **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.

#### 1.6.4

 * **Compliance:** Reworked the WordPress.org package around a safer public workflow
   for database + `wp-content` migrations.
 * **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 `.org` build 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-php` to the latest stable patch release 
   requested in review.

#### 1.6.3

 * **Compliance:** Addressed WordPress.org plugin review feedback round 3 (Review
   ID T3 26Apr26/3.9).
 * **Build:** Added `.distignore` and tightened `build.sh` excludes so vendor `*.
   py`, `*.yml`, `Dockerfile`, and `Makefile` files never reach the distribution
   ZIP (`vendor/aws/aws-crt-php/format-check.py` was the trigger).
 * **Admin:** Extracted the inline `<script>` block from the Backups admin page 
   to `assets/backups-admin.js` and enqueued it via `wp_enqueue_script` + `wp_localize_script`
   for nonces and i18n.
 * **Paths:** Replaced internal `WP_CONTENT_DIR . '/mewp-...'` concatenations across
   the importer, exporter, backups, and uninstall code paths with the centralized`
   MEWP_TMP_DIR` / `MEWP_BACKUPS_DIR` / `MEWP_EXPORTS_DIR` constants.
 * **Security:** Refactored importer AJAX handlers (`ajax_run_import_step`, `ajax_import_progress`)
   to validate request origin via a single `verify_import_request()` helper executed
   before any `$_POST` business 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 via `mewp_escape_sql_identifier()`.
 * **Theme fallback:** Removed direct writes to the core `current_theme` option 
   during post-import recovery; WordPress now derives it from `template`/`stylesheet`.

#### 1.6.2

 * **Meta:** Updated the Wasabi terms link in the readme.
 * **Dependency:** Updated the AWS SDK for PHP to the latest stable patch release
   used by the plugin.

#### 1.6.1

 * **Compatibility:** Reworked the WordPress.org package to satisfy current automated
   review checks.
 * **Security:** Replaced forbidden upload handling in the importer with a safer
   persistence flow.
 * **Meta:** Updated the readme compatibility declaration to WordPress 6.9.

#### 1.6.0

 * **Enhancement:** Improved import/export hardening and WordPress compatibility.
 * **Enhancement:** Better Wasabi, logging, and admin validation flows.
 * **Compatibility:** Updated package preparation for WordPress.org review requirements.

#### 1.5.0

 * **NEW:** Import .wpress files created by All-in-One WP Migration.
 * **NEW:** Automatic format detection — just upload any supported backup file.
 * **Meta:** Updated directory copy and packaging metadata.
 * **i18n:** Updated Spanish translations.

#### 1.4.6

 * **Security:** Moved Wasabi credentials to database settings. Removed hardcoded
   keys.
 * **Enhancement:** Improved UI for settings management.
 * **Privacy:** Added privacy policy integration.
 * **Uninstall:** Complete cleanup on plugin removal.

#### 1.4.5

 * **Rebranding:** Official name update to IDEIDEV Migrator & Backup.
 * **Localization:** Added English and Spanish language support.

#### 1.4.4

 * Initial release of the enhanced exporter.
