-**Please note:** AIO works on Windows in general but due to a bug in `Docker for Windows`, it currently does not support mounting directories from the host into AIO which means that `NEXTCLOUD_DATADIR`, `NEXTCLOUD_MOUNT` do not work and the built-in backup solution is not able to write to the host OS. See https://github.com/nextcloud/all-in-one/discussions/600.
+**Please note:** In order to make the built-in backup solution able to back up to the host system, you need to create a volume with the name `nextcloud_aio_backupdir` beforehand:

E.g. `/mnt/your-drive-mountpoint` will be mounted to `/mnt/your-drive-mountpoint` inside the container, etc.
