+# huaweicloud_gaussdb_opengauss_backup_files
+
+Use this data source to get the list of GaussDB OpenGauss backup files.
+
+## Example Usage
+
+```hcl
+variable "backup_id" {}
+
+data "huaweicloud_gaussdb_opengauss_backup_files" "test" {
+  backup_id = var.backup_id
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `region` - (Optional, String) Specifies the region in which to query the resource.
+  If omitted, the provider-level region will be used.
+
+* `backup_id` - (Required, String) Specifies the ID of the backup.
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - The data source ID.
+
+* `files` - Indicates the list of backup files.
+
+  The [files](#files_struct) structure is documented below.
+
+* `bucket` - Indicates the bucket name.
+
+<a name="files_struct"></a>
+The `files` block supports:
+
+* `name` - Indicates the file name.
+
+* `size` - Indicates the file size.
+
+* `download_link` - Indicates the download link.
+
+* `link_expired_time` - Indicates the link expired time in the **yyyy-mm-ddThh:mm:ssZ** format.
