The folder path that you enter must start with <b>/</b> and must <b>not</b> end with <b>/</b>.<br><br>
An example for Linux is <b>/mnt/backup</b>.<br><br>
On Synology it could be <b>/volume1/docker/nextcloud/backup</b>.<br><br>
For macOS it may be <b>/var/backup</b>.<br><br>
On Windows it might be <b>/run/desktop/mnt/host/c/backup</b>. (This path is equivalent to 'C:\backup' on your Windows host so you need to translate the path accordingly. Hint: the path that you enter needs to start with '/run/desktop/mnt/host/'. Append to that the exact location on your windows host, e.g. 'c/backup' which is equivalent to 'C:\backup'.)<br><br>
Another option is to enter a specific volume name here: <b>nextcloud_aio_backupdir</b>. This volume needs to be created beforehand manually by you in order to be able to use it.<br><br>
