Export/Import会保留workflow的数据么?

不会.

同样不会保留的还有alerts, features, solutions, recycle-bin的状态.

原文段落摘录如下:

You can use the Stsadm export operation to save a site or subsite. Although using the export operation saves data for you, it is not the same as using the backup operation. You cannot save a workflow, alerts, features, solutions, or Recycle-Bin state by using the export operation.
