Description
PolyBright Quick Restore backs up your entire WordPress site — database, media, plugins and themes — into a single .wpqr file, and restores it just as easily. Backups are fully free with no size limit. The free edition restores backups up to 512MB; unlimited restore is available with Quick Restore Unlimited — a one-time purchase, no subscription. Large uploads bypass your host’s upload limit automatically.
Everything here is free
- Full-site backup to a single
.wpqrfile — database, media, plugins, themes. - Restore backups up to 512MB — by uploading the file, or with one click from a backup saved on the server. Larger restores need Quick Restore Unlimited.
- Chunked upload — your host’s upload limit (often 32MB) does not apply. Large files are uploaded in small pieces and reassembled on the server.
- Keep as many backups as you like on the server.
- Serialization-safe URL replacement — restore onto a different domain and your page-builder content and serialized data are rewritten correctly.
- Verify a backup is valid and restorable — without restoring it.
- Import
.wpressfiles made by All-in-One WP Migration — switching is easy; your existing backups just work. - Confirmation before overwrite — you are always asked before a restore replaces the current site.
The free edition is fully functional for backing up sites of any size and restoring backups up to 512MB. There is no trial period and no expiry.
Switching from All-in-One WP Migration?
Your existing .wpress backup files can be imported and restored directly with PolyBright Quick Restore. No re-exporting needed.
Paid editions (optional, from Poly Bright Labs)
If you manage many sites or want hands-off protection, separate paid editions of Quick Restore — available from polybrightlabs.com — add automation that this free plugin does not include:
- Scheduled automatic backups (daily / weekly)
- Backup retention rules (keep the latest N backups)
- Automatic backup before plugin, theme or core updates
- Email alerts on backup success or failure
- Backup encryption
These are additional features delivered separately. The free plugin’s own backup and restore are never limited.
Screenshots
Installation
- In your WordPress admin, go to Plugins Add New, search for “PolyBright Quick Restore”, and click Install Now, then Activate. (Or upload the plugin ZIP under Plugins Add New Upload Plugin.)
- Go to Quick Restore Export and click to create your first backup.

To move a site to a new location, install WordPress at the destination first, then install PolyBright Quick Restore there and restore your backup.
FAQ
-
Is there a size limit on backup or restore?
-
Backups have no size limit. The free edition restores backups up to 512MB — the same limit as All-in-One WP Migration’s free version. To restore larger backups, install Quick Restore Unlimited from polybrightlabs.com: a one-time purchase with no subscription. Chunked upload works regardless of size, so your host’s upload limit is never the problem.
-
My host only allows 32MB uploads. Can I still restore a large backup?
-
Yes. The plugin uploads your backup in small chunks and reassembles it on the server, so your host’s upload limit does not apply.
-
Does restoring overwrite my current site?
-
Yes. Restoring replaces the current site’s database, media, plugins and themes with the contents of the backup. The plugin asks you to confirm before making any changes, so always keep a separate backup of the destination before restoring onto a live site.
-
Can I restore a backup onto a different domain?
-
Yes. During restore the plugin rewrites the backup’s site URLs to the current site’s URL in a serialization-safe way, so a backup taken on one domain works on another.
-
Can I import backups from All-in-One WP Migration?
-
Yes.
.wpressfiles can be imported and restored directly. -
If I delete the plugin, are my backups deleted?
-
No — by default your backups are kept even if you deactivate or delete the plugin. You can choose to delete them on uninstall via a checkbox in Settings, but it is off by default.
-
Where are my backups stored?
-
Inside your site’s
wp-contentdirectory, in a protected folder. You can also download backup files and keep them anywhere.

Changelog
3.0
- The free edition now restores backups up to 512MB, matching the All-in-One WP Migration free model. Backups remain unlimited in size. Restoring larger backups requires Quick Restore Unlimited (one-time purchase, no subscription) from polybrightlabs.com.
- Oversized files are refused before upload begins, so no time is wasted uploading a backup that cannot be restored.
- Added the wpqr_max_restore_size filter so extensions can raise or remove the restore limit.
2.0
- Critical fix: exports were stuck at “Archiving files… 0 done” forever. The resume position between steps was being written to a discarded copy of the state, so every step restarted from the first file and re-archived the same files endlessly. Fixed by passing state by reference. Exports now resume correctly and complete.
- Progress counter now updates live during archiving instead of staying frozen.
1.0.12
- Critical fix: exports could freeze permanently on a single file with no error ever shown. PHP cannot detect or interrupt a blocked file read at the operating-system level (this affects some hosts where wp-content is served from network-attached storage) — no timeout mechanism in PHP can catch it. Files are now checked by size BEFORE being opened, so an oversized or problematic file is skipped with a clear reason instead of silently freezing the whole export. Default limit: 200MB per file (adjustable via the wpqr_max_single_file_size filter).
- Removed a previous “fix” (stream read timeout) that could never have worked, since that mechanism only applies to network sockets, not local files.
1.0.11
- Critical fix: exports no longer freeze at “Archiving files… 0 done” on larger sites. The wp-content file scan now runs in its own step with a full time budget, instead of being crammed into the first request where it could hit the host’s time limit and stall before any file was archived.
- Fixed: .wpress (All-in-One WP Migration) files were rejected on upload despite being advertised as supported — they are now correctly accepted for restore.
1.0.10
- Critical fix: exports could freeze permanently (“Archiving files… 0 done”) when a single file read stalled — most commonly on network-backed storage used by some managed WordPress hosts. Reads are now bounded with a 20-second timeout, so a stalled file now fails cleanly and reports an error instead of hanging the export forever.
- Hardening: the export’s internal time-slice check now runs on every file, including skipped/unreadable ones, so it always yields back to the browser on schedule.
1.0.9
- Security fix: restore-continuation requests now require a cryptographic match of the per-restore secret key instead of trusting client-supplied flags, closing a CSRF gap flagged in review.
1.0.8
- Internal consistency fixes: copyright line and code comments now correctly say Poly Bright Labs throughout.
1.0.7
- Renamed to PolyBright Quick Restore (permalink: polybright-quick-restore).
1.0.6
- Fixed: migrating to a site with a different table prefix no longer locks out administrators (prefix-dependent keys such as capabilities and user roles are now correctly rewritten, while all other data is preserved verbatim).
- Fixed: serialized settings containing the site URL (widgets, theme options, page-builder data) are now rewritten with correct string lengths instead of being silently discarded after migration.
- Security: removed an unauthenticated diagnostic endpoint that disclosed server paths and versions; progress polling no longer exposes filesystem paths.
- Removed an unused server-side loopback request; the plugin now makes no outbound HTTP requests at all.
1.0.5
- Critical fix: media images no longer break after restore. The database prefix replacement was corrupting metadata keys such as _wp_attached_file; it now only affects table names, never row data.
1.0.4
- Major upload speed improvement: larger upload chunks mean far fewer requests (a 30MB file now uploads in ~6 requests instead of ~120).
1.0.3
- Fixed “Security check failed (403)” error when restoring a saved backup; the security token is now sent on all restore actions.
1.0.2
- Fixed a stray code comment that displayed on the restore screen and corrupted the confirmation dialog.
1.0.1
- Fixed restore confirmation dialog: resolved a false “request failed” message and populated the backup details (source, date, WordPress version).
1.0.0
- First public release of PolyBright Quick Restore.
- Full-site backup of any size; restore up to 512MB free (unlimited with Quick Restore Unlimited).
- Chunked upload that bypasses the host upload limit.
- One-click restore from saved backups, plus restore by upload.
- Serialization-safe URL replacement for cross-domain restores.
- Backup verification.
- Import of All-in-One WP Migration (.wpress) files.
- Backups are kept by default on uninstall (opt-in deletion).
