Most WordPress site backups and migrations complete in 10-30 minutes, depending on site size and hosting server resources. ### How long do I have to restore my backup? Backups and their restore codes are valid for 48 hours after creation. After that the backup is deleted from our servers and you’ll need to run a fresh backup. ### What if I lose the restore code email? The restore code is the only way to download your backup, and we cannot retrieve a lost code. If you don’t see the email, check spam — otherwise just run the backup again to get a new code. ### Can I backup only specific parts of my WordPress site? Yes! Use the advanced options to selectively backup and migrate your database, plugins, uploads, or themes. Perfect for large WordPress sites. ### Does 1-Click Migration work with WordPress Multisite? Not currently. The plugin is optimized for single WordPress site backup and migration. ### Will my URLs update automatically during WordPress migration? Yes! 1-Click Migration automatically updates all database entries including serialized data when you migrate your WordPress site to a new domain. ### How long do I have to restore my WordPress backup? WordPress backups are available for 48 hours after creation. You can create a new backup anytime if you miss the restoration window. ### Is there a limit on WordPress site size for backup and migration? No! Unlike other WordPress migration plugins, 1-Click Migration handles sites of any size completely free. Large sites over 1GB can use selective restore options. ### Can I use this for WordPress staging site setup? Absolutely!

Collaboratori * [ 1clickmigration ](https://profiles.wordpress.org/1clickmigration/) [Traduci “1 Click Migration & Backup: Free WordPress Migration Plugin with Zero Downtime & Easy Clone” nella tua lingua.](https://translate.wordpress.org/projects/wp-plugins/1-click-migration) ### Ti interessa lo sviluppo? [Esplora il codice](https://plugins.trac.wordpress.org/browser/1-click-migration/) segui il [repository SVN](https://plugins.svn.wordpress.org/1-click-migration/), segui il [log delle modifiche](https://plugins.trac.wordpress.org/log/1-click-migration/) tramite [RSS](https://plugins.trac.wordpress.org/log/1-click-migration/?limit=100&mode=stop_on_copy&format=rss). ## Changelog #### 3.1.4 * **Log Noise Reduction**: Suppressed unrelated theme/plugin PHP errors after migrations finish and deduplicated identical PHP errors across requests while migrations are active. #### 3.1.3 * **User Guidance**: Added contextual “How to fix” messages for quota, write permission, loopback, download/decrypt/extract, and database import failures. #### 3.1.2 * **Restore Reliability**: Restore now fails clearly when disk quota or write permissions prevent downloads, decryption, or ZIP extraction instead of reporting partial files as restored. * **Restore Diagnostics**: Added a restore workspace write probe and hardened DB failure-context logging for malformed SQL payloads. #### 3.1.1 * **Backup Diagnostics**: Added admin-ajax loopback and worker dispatch logging to help identify hosts that block background backup workers. #### 3.1 * **Restore Reliability**: Fixed PHP fallback database imports on hosts where ` proc_open` is disabled so comment-prefixed SQL table definitions are imported correctly. * **Restore Safety**: Database import errors now stop the restore and surface a clear failure instead of logging `Restore completed.` * **Restore Validation**: Restore now verifies the imported `siteurl` option before running URL replacement. #### 3.0 * **MAJOR UPDATE — please install.** Older versions will stop working soon as the legacy backup endpoint is retired. Update now to keep backup and restore functional. * **Redesigned Admin UI**: New tabbed Backup / Restore interface with clearer steps, inline help, progress card, and a yellow notice banner that surfaces the email/ restore-code reminder after a backup completes. * **Simpler Restore Access**: Backup now uses your email and sends an 8-character restore code when the backup completes. Restore takes only that code — no separate email field needed. * **Pre-Flight Disk Space Check**: Backup and restore exit early with a clear message if there’s not enough free disk space, instead of failing midway. * **Backup Security**: Files continue to be encrypted (AES-256) before upload, with improved key handling behind the scenes. * **Retention**: Backup availability is now consistently 48 hours. * **Backup Reliability**: Improved backup stability on sites with plugins that interfere with long-running background tasks. * **Restore Reliability**: Improved restore stability when plugin code, locked folders, or stubborn file permissions would previously interrupt a migration. * **Security**: Removed the old legacy access path and tightened the restore flow. * **Compatibility**: Existing backups from the previous version remain restorable during the short upgrade window only. #### 2.6.1 * **Critical Fix**: Fixed fatal `Call to undefined function OCM\ini_set()` crash on shared hosts that disable `ini_set`/`ini_get` via `disable_functions` — this was a 100% restore blocker on affected cPanel hosts * **Critical Fix**: Fixed “OS: Windows” log message being written 250+ times per backup on Windows/XAMPP hosts — now logs only once per session * **Bug Fix**: Fixed fatal crash when Stop & Reset is clicked mid-backup — background process now re-creates the temporary directory if it was deleted #### 2.6.0 * **Critical Fix**: Fixed DivisionByZeroError crash during database backup when tables report 0 MB in information_schema (affected Gravity Forms and other small tables) * **Bug Fix**: Changed error catch from `Exception` to `Throwable` so PHP 8 DivisionByZeroError is properly caught by the fallback handler * **Log Noise Reduction**: Added error deduplication to suppress identical PHP errors from being logged 30+ times per session (e.g. theme/plugin bugs) * **Log Noise Reduction**: Suppressed per-table “Table being backed up” log messages that generated 50-80+ lines per backup on large sites * **Log Fix**: Fixed misleading “Bucket created” log message that appeared after AWS 502 errors — now correctly says “Retrying bucket creation” #### 2.5.9 * **Maintenance Mode**: Automatically enables maintenance mode during restore to prevent visitors from seeing broken pages, white screens, or database errors * **Admin & API Bypass**: Admin users and REST API requests (e.g. progress polling) bypass maintenance mode so the dashboard stays functional * **Progress Indicator**: The admin progress endpoint now reports maintenance mode status so the dashboard indicator works * **Auto Cleanup**: Maintenance mode is automatically disabled when the restore completes or is cancelled via Stop & Reset #### 2.5.8 * **Timeout Fix**: Reset PHP time limit before each major operation (archive, encrypt, upload, download, decrypt, extract) to prevent timeouts on large sites * **Upload Fix**: Upload timeout now uses the full execution budget instead of the exhausted background process remaining time * **Download Fix**: Restore file downloads now use the full timeout budget instead of remaining background process time * **Bug Fix**: Fixed `Undefined array key "tables"` crash when mysqldump fails and falls back to PHP-based export * **Bug Fix**: Fixed `error_reporting` never being restored on success paths in zip creation and folder backup * **Resilience**: Error handler no longer kills the process for fatal errors from external themes/plugins (e.g. WooCommerce dependency in child themes) * **Reliability**: Added pre-flight disk space check before DB and folder backups to fail early with a clear message * **Cleanup**: Removed dead `retry` parameter from `wp_remote_post` calls #### 2.5.7 * **Bug Fix**: Fixed fatal error during restore where `$presigned_urls` (stdClass) was passed to `sprintf` instead of the directory path string * **Bug Fix**: Made `mkdir` recursive when creating `tmp/db/` directory so it succeeds even if the parent `tmp/` directory was cleaned up * **Restore Fix**: Clear stale background process queues after DB import to prevent source site’s backup tasks from firing on the destination #### 2.5.6 * **Concurrency Fix**: Added MySQL advisory locks to prevent concurrent background handlers from processing the same batch simultaneously * **Reliability**: Fixed race condition where multiple handlers could duplicate compress, encrypt, and upload operations * **Upload Fallback**: Improved upload step to construct expected encrypted file path when step metadata is missing, preventing silent upload skips #### 2.3.7 * **Progress Bar Fix**: Resolved progress bar jumping back to 1% during database backup operations * **Memory Management**: Implemented dynamic memory management with automatic page sizing based on available system resources * **Error Handling**: Added robust validation and error handling for S3 file uploads with proper file path checking * **Logging Improvements**: Enhanced logging system with better filtering to prevent progress bar interference from verbose messages * **Debug Tools**: Added conditional debug logging (WP_DEBUG only) to help identify unmapped progress messages * **Database Optimization**: Improved database export operations with dynamic row increment sizing and better memory monitoring #### 2.3.6 * **Reliability Fix**: Disabled async dispatch in favor of direct processing for guaranteed execution on all hosting environments * **Compatibility**: Resolved backup hanging issues on AWS and other servers where async HTTP requests may fail silently * **Stability**: Reverted to proven direct processing approach for maximum reliability across all hosting providers #### 2.3.5 * **UX Improvement**: Disable Backup/Restore buttons when all components are excluded to prevent empty backups * **UX Improvement**: Fixed progress bar jump from 1% to 0% at the start of backup/ restore operations * **Bug Fix**: Added validation to prevent silent failures when attempting to backup with all components excluded #### 2.3.3 * **Bug Fix**: Fixed `is_processing()` method compatibility issue with different WP Background Processing library versions * **Compatibility**: Replaced method call with direct transient check for maximum compatibility #### 2.3.2 * **Security Fix**: Added nonce verification and capability checks to prevent unauthorized access (CVE-2025-3455) * **Reliability**: Simplified background processing for maximum compatibility across all hosting environments * **UX Improvement**: Fixed progress bar freeze after restore completion and login * **Performance**: Removed async complexity that caused race conditions on various hosts * **Compatibility**: Enhanced stop & reset functionality to prevent stuck states #### 2.3.1 * Fixed white screen on deactivation * Improved retry logic for presigned URLs * Enhanced cleanup & error handling #### 2.3 * Stability improvements #### 2.2 * CSRF fix & updates #### 2.1 * Bug fixes #### 2.0 * Full redesign for easier use * Multiple bug fixes #### 1.6 * Manual & automated retries * Improved hosting compatibility #### 1.4 * Selective backup/restore added * Stop & Reset button implemented #### 1.3 * Support for serialized DB entries * PayPal integration #### 1.0 – 1.2 * Initial release & dependency updates ## Meta * Versione **3.1.4** * Ultimo aggiornamento **3
