Description

Luzid Backup to Nextcloud uploads your existing WordPress backup files to a Nextcloud folder via WebDAV.

It is designed for two main workflows:

Automate offsite copies: upload backup archives on a schedule (WordPress Cron).
Manual runs + monitoring: start uploads manually and follow progress + logs.

Typical use cases:

Keep an offsite copy of backup archives generated by popular backup plugins.
Upload backups to a structured Nextcloud folder (per source, per domain).
Reduce storage usage with optional rotation (keep only the last N backup sets per source).

Core concepts:

Sources – each source represents a folder where backup files are created (UpdraftPlus, BackWPup, WPvivid, All-in-One WP Migration, Duplicator, or custom).
Upload – the plugin scans sources for backup files and uploads them to Nextcloud via WebDAV PUT.
Streaming – files larger than 2 MB are uploaded via cURL streaming (reads from disk, never loads the entire file into RAM). This prevents memory and timeout issues on shared hosting.
Schedule – optional daily/weekly/monthly runs at a fixed time (WordPress Cron; traffic-dependent).
Rotation – keep the newest N backup sets and remove older ones on Nextcloud.
Email Reporting – get notified on successful or failed transfers.

Click Save Settings.

3. Manual Upload

Does this plugin create backups?

No. It uploads backup archives created by other tools. Configure your backup plugin first.

Why does the schedule not run exactly on time?

WordPress Cron is traffic-based. If the site has no visits around the scheduled time, the run may be delayed.

Should I use a normal password or an app password?

Always use a Nextcloud App Password (Settings Security Devices & Sessions).

My upload gets stuck on large files

The plugin streams files larger than 2 MB via cURL to avoid PHP memory limits. If uploads still time out, check your hosting provider’s PHP max_execution_time setting.

The password field is filled with the wrong password

Click the eye icon next to the password field to reveal and verify the content. The field uses autocomplete="new-password" to prevent browser autofill, but some browsers may still fill it. Clear the field and enter your Nextcloud app password manually.

Reviews

Changelog

1.3.0

Streaming uploads: Files > 2 MB are now uploaded via cURL streaming (reads from disk, never loads entire file into RAM). Solves timeout and memory issues on shared hosting with large backup files.
Context-aware buttons: Each tab shows only the relevant action buttons. Setup shows only “Save & Test”; Backup Sources and Schedule show “Save Settings”; How-To hides all buttons.
Upload button gating: “Start Manual Upload” is disabled (greyed out) until at least one backup source is enabled.
Password field improvements: Visibility toggle (eye icon), autocomplete="new-password" to prevent browser autofill, renamed form field name to avoid browser recognition.
Removed “Remove password” checkbox: Passwords are now simply replaced by entering a new one.
Default source paths: Backup source paths and file extensions always fall back to sensible defaults (even after reset). Empty fields are never saved – defaults are restored automatically.
“Delete All Settings” preserves defaults: Resetting the plugin now keeps default source paths and extensions intact, only clears user configuration, logs, and schedule.
Guided setup flow: New hint text on Setup tab guides users through the configuration process.
Updated How-To guides: German and English documentation rewritten to match current UI and features.
Fixed: $log / $source / $s variable reference bugs from prefix renaming.
Fixed: Sources tab fields (path, extensions) now save correctly.
