Explanation The ModifyDBInstanceSpec API call changes RDS instance specifications, but it can fail for several reasons. The instance type or specification must be included in the request parameters, otherwise the API has incomplete information. If a backup task is running, the operation will fail because you cannot modify specs during an active backup. Disaster recovery instances are read-only replicas and cannot have their specifications modified directly. Regular instances can be modified, but the other two conditions prevent the operation from succeeding.
