Nextcloud, ownCloud, Synology, QNAP and most other NAS systems offer a WebDAV address for a folder. That address, a user and a password are all the app needs.
Files, the settings cog at the bottom left, WebDAV: an address like https://cloud.example.com/remote.php/dav/files/USER/. Add the folder you want at the end, for example https://cloud.example.com/remote.php/dav/files/USER/Photos. Make the folder first in Files.
The same place: https://cloud.example.com/remote.php/dav/files/USER/Photos.
Install WebDAV Server from the Package Center and enable HTTPS. The address is https://nas.example.com:5006/Photos, where Photos is a shared folder the user may write into.
Turn WebDAV on in the file service settings, with HTTPS, and use the shared folder's address.
The address must start with https://. The app refuses a plain http:// address: your password would travel in the clear.
- Nextcloud and ownCloud: make an app password (Settings, Security, Devices & sessions) and use that instead of your sign-in password. It can be revoked on its own, and it works when two-factor sign-in is on.
- A NAS: a user that may write into the shared folder, ideally one made only for this.
- Me, Settings, Backup, Storage backend. Pick WebDAV folder.
- Name: for example Nextcloud.
- Folder URL: the address from step 01.
- User and Password: from step 02.
- Pick Originals or 1080p, tap Test connection, then Save and start backup. See Test connection, Save.
Inside the folder you gave, the app makes one folder named after your index and writes only there. See what is written into your storage.
