Luzid Backup to Nextcloud

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

It is designed for two main workflows:

1. Automate offsite copies: upload backup archives on a schedule (WordPress Cron).
2. 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.
