这项专利的快速备份单元(RBU)提供快速访问到最新的编程软件，轻松存储单独编程的数据。
This patented rapid backup unit (RBU) provides fast access to up-to-date programming software and easily stores individually programmed data.
部署管理器必须具有单元中所有节点的全部信息，因此备份目录必须来自于V5部署管理器节点。
The deployment manager must have complete information for all nodes in the cell, so the backup directory must come from the V5 deployment manager node.
另外，可以使用ibm云中克隆持久性存储单元的功能来创建一个定制的备份与恢复解决方案，或许可以带来额外的好处。
Additionally, it may be possible to create a customer backup and restore solution using the IBM Cloud abilities of cloning a persistent storage unit that may provide additional benefits.
本pprc设置示例包括两个存储单元，一个位于生产站点，另一个位于备份站点。
This sample PPRC setup consists of two storage units; one is located at the production site and another is at a backup site.
较大型的单元大多采用电池、飞轮、柴油电机或三者的组合作为备份电源。
Most of the larger units use batteries, flywheels, diesel generators, or a combination of the three, acting as a backup power source during power quality or utility disturbances.
每两个单元间具有视频交叉链路通信路径，将能够进行系统备份。
A video cross link communication path between both units will enable system redundancy.
如果没有此类备份，您的唯一选择将是回滚整个计算单元。
Without such a backup, your only option is to roll back the entire cell.
因此，如果您失去运行部署管理器的数据中心，也就失去了管理计算单元的能力，直到仍然存在的数据中心启动备份部署管理器为止。
As a result, if you lose the data center where the deployment manager is running, you lose the ability to manage the cell until a backup deployment manager is brought up in the surviving data center.
之所以需要如此多的备份，是因为它们可以在您需要时让您轻松返回计算单元迁移中的任何步骤。
The reason so many backups are necessary is to enable you to easily go back to any step in your cell migration, should the need arise.
本文将介绍此工具的基础知识，并重点关注混合单元迁移中的各种备份选择。
The basics of the tool are described here with a specific focus on options for mixed cell migration backups.
要将此节点设置为备份，您需要自动复制部署管理器的计算单元范围的配置。
To set up this node as a backup, you need to automatically replicate the deployment manager's cell-wide configuration.
若要向某个用户授予备份和还原权限，请使用“组策略”管理单元。
To grant a user backup and restore rights, use the Group Policy snap-in.
