Cause

这是预期的行为。VMware 不支持为总线共享配置的虚拟机的快照。请参阅 VMware 文章使用快照 此超链接会将您带往 Dell Technologies 之外的网站。

管理虚拟机 如果虚拟机配置为总线共享,则 Create Snapshot 选项在 VMware 中不可用(不可用):

Resolution

由于 VMware 无法为虚拟机拍摄快照,因此 NetWorker VMware Protection (NVP) 备份不支持虚拟机。将虚拟机从配置它的任何 NetWorker 保护组中删除。

要备份此虚拟机,请在虚拟机上安装 NetWorker 客户端软件,并配置 NetWorker 客户端以备份系统。有关安装和配置 NetWorker 客户端的信息,请参阅 NetWorker 安装NetWorker 管理 指南 。NetWorker 文档和软件可在戴尔支持 NetWorker 产品页面上找到。
