## 説明

**PWS Backup & Migration** by [Professional Web Solutions](https://pwsolution.com/)
lets you export, import, store, and restore complete WordPress sites using the proprietary`.
pws` archive format.

Professional migration and WordPress services are available from the plugin author.

#### Features

 * One-click full site export to `.pws`
 * Chunked upload for unlimited import size
 * Local backups management (download, restore, delete)
 * Pre-restore validation (archive, disk, PHP, WP, MySQL)
 * URL search & replace during migration
 * SHA-256 checksums for archive integrity
 * Smart exclusions (cache, logs, dev folders)

#### Privacy

 * **Telemetry:** NONE
 * **External services:** NONE
 * **Remote API calls:** NONE (except loopback AJAX for pipeline continuation)

All backup operations run locally on your server. No data is sent to third parties.

### Developer Notes

Filter `pwsbami_archive_chunk_size` to adjust archiver read/write chunk size (default
524288 bytes).
 Filter `pwsbami_export_exclude_path` to exclude additional paths
from export.

your database, uploads, plugins, themes, and migration metadata.

### Does this plugin send data externally?

No. Telemetry is NONE, external services are NONE, and remote API calls are NONE.

### Can I migrate large sites?

Yes. The plugin uses chunked uploads and a multi-step AJAX pipeline to handle sites
of any size.

## 変更履歴

#### 1.0.11

 * Much faster exports: time-budget packing (no 150-file hard cap) like All-in-One
   WP Migration
 * Mid-file resume for large media so packing no longer stalls on big files
 * Fix database export hang caused by rewriting the whole queries file every batch
 * Keyset DB pagination, clearer database progress, and near-instant AJAX step chaining

#### 1.0.10

 * Auto-remove duplicate plugin folders on activation (fixes multiple “PWS Backup&
   Migration” rows after zip upload)
 * Admin notice with one-click cleanup when duplicate installs are detected

#### 1.0.9

 * Faster file packing: single-pass SHA-256 while writing (no double disk read)
 * Stream file list from disk with byte-offset resume (no 39k-path memory load per
   request)
 * Smaller packing steps (150 files / 12s) for strict shared-hosting timeouts
 * Export retries use exponential backoff (up to 20 attempts); refresh page to resume
   after failure

#### 1.0.8

 * Fix large-site export timeouts: chunked resumable file scanning with per-step
   time budget
 * Export pipeline retries transient AJAX failures (up to 10 attempts) and auto-
   resumes after page refresh
 * Safer default step sizes for shared hosting (500 files / 20s per request)

#### 1.0.7

 * Move local backup storage to uploads/pws-backup-migration/backups/ (migrate legacy
   wp-content/pws-backups/ on activation)
 * Replace direct ABSPATH/WP_CONTENT_DIR usage with WordPress path helpers (get_home_path,
   get_theme_root, wp_upload_dir, plugin_dir_path)
 * Harden import extract with archive path allowlisting and traversal checks

#### 1.0.6

 * Prefix template and uninstall variables for Plugin Check / PHPCS compliance

#### 1.0.4

 * Store runtime work files in the uploads directory instead of the plugin folder

 * WordPress.org Plugin Check compliance (no hidden files in plugin package)
