Can you Pls consider to let user use webdav cloud to sync backups? It Will be many helpful! Thanks a lot!
For backups, there is nothing specific to WebDav we would need to do. As soon as we support automatic backups using the StorageAccessFramework, they can be saved anywhere (nextcloud, WebDAV, Google Drive, etc).
However, synchronization is a whole different thing. That needs a dedicated server, not just file storage.
