## 外掛說明

**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.
