WebDAV

Store backups on any WebDAV-compatible server - Nextcloud, ownCloud, Synology, Apache, and more.

Configuration

Field	Description	Default	Required
Name	Friendly name for this destination	-	✅
URL	WebDAV endpoint URL	-	✅
Username	WebDAV username	-	✅
Password	WebDAV password or app password	-	❌
Path Prefix	Subfolder path on the server	-	❌

Setup Guide

1. Obtain the WebDAV URL from your provider (see examples below)
2. Go to Destinations → Add Destination → WebDAV
3. Enter the URL, Username, and Password
4. (Optional) Set a Path Prefix to organize backups in a subfolder
5. Click Test to verify the connection

Nextcloud / ownCloud Setup

1. WebDAV URL format: https://your-cloud.example.com/remote.php/dav/files/USERNAME/
2. Recommended: Create an App Password under Settings → Security → Devices & Sessions instead of using your account password
3. Set Path Prefix to e.g. Backups/DBackup

Synology NAS WebDAV Setup

1. Enable WebDAV in Package Center → install WebDAV Server
2. Configure HTTPS port (default: 5006) under WebDAV Server → Settings
3. WebDAV URL: https://your-nas:5006/
4. Use Path Prefix to target a specific shared folder

How It Works

• Files are uploaded via HTTP PUT to the WebDAV endpoint
• DBackup creates subdirectories per job within the Path Prefix automatically
• All credentials are stored AES-256-GCM encrypted in the database
• Supports both HTTP and HTTPS endpoints

Troubleshooting

401 Unauthorized

401 Unauthorized

Solution: Check username and password. For Nextcloud, use an App Password instead of your account password (especially with 2FA enabled).

405 Method Not Allowed

405 Method Not Allowed

Solution: Verify the WebDAV URL is correct. A common mistake is using the web UI URL instead of the WebDAV endpoint.

SSL Certificate Error

UNABLE_TO_VERIFY_LEAF_SIGNATURE

Solution: Ensure your server has a valid SSL certificate. For self-signed certs, set NODE_TLS_REJECT_UNAUTHORIZED=0 (not recommended for production).

MKCOL Failed

409 Conflict

Solution: The parent directory doesn't exist. Create the target folder manually in your WebDAV client or adjust the Path Prefix.
