# AnalysisLogExportS3OutputConfiguration
<a name="API_AnalysisLogExportS3OutputConfiguration"></a>

Contains output information for an analysis log export with an S3 output type.

The exported logs are written under the bucket and key prefix that you specify. The path includes the collaboration ID, the protected query ID, and the analysis log export ID. Because the path includes the export ID, exporting the same query more than once doesn't overwrite the logs from an earlier export.

**Note**  
The exported logs are encrypted using the default encryption configuration of the destination bucket. AWS Clean Rooms doesn't accept a KMS key for log export. To encrypt the exported logs with a customer managed key, configure the bucket's default encryption to use that key before you export.
