Error=“java.io.IOException: [ReadFile] (381) The cloud operation is not supported on a read-only volume” on OneDrive
This error is only seen when backing up a local OneDrive folder on a Windows device. It isn’t seen when backing up OneDrive data from the cloud using our cloud-to-cloud connector.
OneDrive creates symbolic links on a PC which point to the folders and files on their cloud service. It doesn’t download the files until the user accesses them. This means our software detects what it believes to be a file, but is only a read-only link.
Our software comes with cloud-to-cloud connectors in the desktop and server versions. These allow you to backup the main cloud storage and drive services.
The cloud-to-cloud connectors are free to use.
