Step 6: Upload the Manifest File to an Amazon S3 Bucket

Upload the manifest file to an Amazon S3 bucket. If the Amazon S3 bucket does not reside in the same region as your Amazon Redshift cluster, you must use the REGION option to specify the region in which the manifest is located. For information about creating an Amazon S3 bucket and uploading a file, see Amazon Simple Storage Service Getting Started Guide.
