I have taken a database backup on AWS S3 and getting errors while trying to restore it. This error is suggesting me to decrease cluster nodes to 1 but in my case, It is not possible to decrease nodes. Is there any other way available? Or if anyone knows how to copy an online database to another database that will also work in my case.
**Error Message:**
{
"message": "To ensure consistency is maintained in the cluster file-based restore may only run on a cluster with a single node. Please scale the cluster down to a single Stardog node before restoring this backup. After it completes you can scale the cluster back to the desired number of nodes.",
"code": "00UOE2"
}
