Upload the `stalza-backup` folder to `/wp-content/plugins/` 2. Activate the plugin through the Plugins menu 3. Open **Stalza Backup** in the admin menu ## FAQ ### Does Free require a cloud account? No. Local storage and download work without any external account. ### Is verification Free? Yes. Verification and backup manifests are core Free features. ### How do scheduled backups run? Through WordPress cron (`stalza_backup_cron_run`). On hosts where WP-Cron is unreliable, trigger it with a real system cron calling `wp cron event run`. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Stalza Backup” is open source software.

[Browse the code](https://plugins.trac.wordpress.org/browser/stalza-backup/), check out the [SVN repository](https://plugins.svn.wordpress.org/stalza-backup/), or subscribe to the [development log](https://plugins.trac.wordpress.org/log/stalza-backup/) by [RSS](https://plugins.trac.wordpress.org/log/stalza-backup/?limit=100&mode=stop_on_copy&format=rss). ## Changelog #### 1.0.10 Bug Fixes: * Allow deleting any backup after confirm (no longer block the last verified backup). * Large imports use a light structure check so multi-GB uploads finish; treat completed imports as restorable. * Restart orphaned chunked uploads after wiped import sessions; treat Cloudflare 5xx/520 HTML as transient during job polling. #### 1.0.8 Bug Fixes: * Large backup downloads no longer die mid-transfer: download tokens scale with file size (up to 24h) so browser resumes stay valid. * Stream multi-GB backups to disk via Chrome/Edge save dialog (Range chunks + retries) instead of assembling the zip in RAM. * Harden PHP download streaming (8 MiB chunks, disable nginx buffering, release session lock) and block in-memory fallback above 100 MiB. #### 1.0.9 Bug Fixes: * Chunked backup import uploads (2 MiB slices) so large zips no longer hit nginx/ PHP single-request body limits (413). #### 1.0.7 Features: * Signed admin download links (short-lived HMAC tokens) for faster native browser downloads without public static zip URLs. * Resumable native SHA-256 checksum phase for large archives (HashContext across ticks, pure-PHP fallback). Performance: * Archive phase respects a per-tick byte budget so zip close stays within proxy/ time limits. * Admin UI prefers native download when a signed link is available, with chunked Range fallback. Bug Fixes: * After restore, reset foreign `stalza_backup_storage_path` / upload paths that point outside the destination install. * Clear PHPStan findings in job runner / hasher paths; Plugin Check ERROR-clean on free build. #### 1.0.6 Bug Fixes: * Stop writing `$wpdb->prepare()` `%` placeholder hashes into SQL dumps (Elementor` settings="%7B%7D"` / site-logo fatals). * Exclusive job lock so admin ticks and WP-Cron cannot double-append `filelist. txt`. * Heal prepare-placeholder corruption on restore and rewrite absolute URLs in uploads CSS (Elementor google-fonts CORS). * Remap option/usermeta keys and unknown collations when restoring custom table prefixes. * Stream large zip downloads with Range support; clear Plugin Check ERROR/WARNING findings. Features: * Stronger site-to-site restore: prefix rewrite, serialize-safe URL remap, JSON- escaped URL pairs, and uploads text-file remaps. #### 1.0.5 Bug Fixes: * Set WordPress.org Contributors to valid username `fuadkm`. #### 1.0.4 Features: * Site-to-site restore: automatic table-prefix rewrite and serialize-safe URL remapping when source and destination differ. * Restore-completed modal with Go to login (sessions are usually reset after DB restore). Bug Fixes: * Dump pagination uses `ORDER BY` primary/unique key so large tables do not emit duplicate PKs. * Persist SQL restore offset mid-tick and rewrite `INSERT` to `REPLACE` so resume cannot fail on Duplicate entry. * Restore ticks survive session wipe via tick token (omit stale REST nonce; clear cookie check when token present). * Harden staging cleanup and prune missing `active_plugins` after restore so incomplete plugin copies cannot fatal the site.
