当我瞄准由Synology DS211磁盘工作站托pipe的networking共享时，为什么我的备份失败？

当我尝试使用由Synology DS211磁盘工作站托pipe的networking共享时，我的备份失败。 他们工作正常，如果我的目标不同的networking共享（即\服务器1 \数据\ larry）。

当我运行以下命令：

Wbadmin start backup -backupTarget:\\diskstation\backup-larry -include:C: 

这是我得到的：

备份将创build以下path\\diskstation\backup-larry\WindowsImageBackup\LARRY-MYDOMAIN\但其为空。

• 持续备份testing？
• WBAdmin系统状态问题
• 设置MySQL数据库的自动备份，包括表锁等 – MySQL Workbench？
• Amazon S3网站和MySQL备份
• 哪个是Ubuntu邮件服务器最好的开源邮件账户备份解决scheme？

我对目标目录（\ diskstation \ backup-larry）具有读写权限。 我已经通过查看权限和实际上将文件复制到此位置来validation这一点。

有什么build议么？

 Wbadmin start backup -user:<username> -password:<password> -backupTarget:\\diskstation\backup-larry -include:C:
