# ExportSnapshot
<a name="API_ExportSnapshot"></a>

Exports the data of an enhanced snapshot to an Amazon S3 location. Managed Service for Apache Flink assumes the IAM role that you specify in `ExportDestinationConfiguration` to write the snapshot data. The snapshot must be in the `READY` status.

This operation is asynchronous. To track the progress of the export, use `DescribeSnapshotOperation`.

A snapshot can have only one export in progress at a time. If an export of the snapshot is already in progress, `LimitExceededException` is returned.

For more information, see [Import and export](https://docs.aws.amazon.com/managed-flink/latest/java/snapshots-import-export.html).
