public void setExportPath(String exportPath) {
        this.exportPath = exportPath;
    }
<p>
(Optional) Specifies the path in the Amazon S3 bucket where the root of your Amazon FSx file system is exported.
The path must use the same Amazon S3 bucket as specified in ImportPath. You can provide an optional prefix to
which new and changed data is to be exported from your Amazon FSx for Lustre file system. If an
<code>ExportPath</code> value is not provided, Amazon FSx sets a default export path,
<code>s3://import-bucket/FSxLustre[creation-timestamp]</code>. The timestamp is in UTC format, for example
<code>s3://import-bucket/FSxLustre20181105T222312Z</code>.
</p>
<p>
The Amazon S3 export bucket must be the same as the import bucket specified by <code>ImportPath</code>. If you
specify only a bucket name, such as <code>s3://import-bucket</code>, you get a 1:1 mapping of file system objects
to S3 bucket objects. This mapping means that the input data in S3 is overwritten on export. If you provide a
custom prefix in the export path, such as <code>s3://import-bucket/[custom-optional-prefix]</code>, Amazon FSx
exports the contents of your file system to that export prefix in the Amazon S3 bucket.

This parameter is not supported for file systems with a data repository association.
