我正在考虑为 RavenDB 编写一个导入/导出例程，以便我可以在本地的完整服务器实例上进行开发，但由于资源限制可以嵌入在网站上运行。我希望能够在网站的锁定部分管理功能，以允许从文件进行备份和恢复。但我也希望能够将生产数据集恢复到本地服务器实例中，以用于调试和开发目的。

作为其中的一部分，我一直在研究使用 v2.5.2750 的 ISmugglerApi 接口，特别是 Raven.Database.Smuggler.DataDumper 和 Raven.Smuggler.SmugglerApi 实现。

我可以使用嵌入式实例进行备份和恢复。我可以很好地备份服务器实例并将此文件导入嵌入式实例。但是，还原到服务器数据库是出现问题的地方。

我正在使用的代码如下：

恢复代码：

        SmugglerOptions smugglerOptions = new SmugglerOptions { BackupPath = Server.MapPath(ServerMapPath) };
        switch (Context)
        {
            case Context.Embedded:
                DataDumper dumper = new DataDumper(((EmbeddableDocumentStore)MvcApplication.Store).DocumentDatabase, smugglerOptions);
                var embeddedImport = dumper.ImportData(smugglerOptions);
                await embeddedImport;
                break;

            case Context.Server:
                var connectionStringOptions = new RavenConnectionStringOptions
                {
                    ApiKey = Configuration.ApiKey,
                    DefaultDatabase = Configuration.DefaultDatabase,
                    Url = Configuration.DefaultUrl
                };

                var smugglerApi = new SmugglerApi(smugglerOptions, connectionStringOptions);
                var serverImport = smugglerApi.ImportData(smugglerOptions);
                await serverImport;
                break;
        }

备份代码：

        SmugglerOptions smugglerOptions = new SmugglerOptions { BackupPath = Server.MapPath(ServerMapPath) };
        switch (Context)
        {
            case Context.Embedded:
                DataDumper dumper = new DataDumper(((EmbeddableDocumentStore)MvcApplication.Store).DocumentDatabase, smugglerOptions);
                var embeddedExport = dumper.ExportData(null, smugglerOptions, false);
                await embeddedExport;
                break;

            case Context.Server:
                var connectionStringOptions = new RavenConnectionStringOptions
                {
                    ApiKey = Configuration.ApiKey,
                    DefaultDatabase = Configuration.DefaultDatabase,
                    Url = Configuration.DefaultUrl
                };

                var smugglerApi = new SmugglerApi(smugglerOptions, connectionStringOptions);
                var serverExport = smugglerApi.ExportData(null, smugglerOptions, false);
                await serverExport;
                break;
        }

ServerMapPath 当前是 App_Data 文件夹中文件名称的 const 字符串。

Configuration.* 是一个简单的静态类，用于从 web.config 中读取所需设置的值。

上下文是一个配置选项，用于指定运行环境的类型。

当我在服务器数据库配置中运行恢复时，我得到以下信息：
