示例：还原 Teradata QueryGrid
要还原系统，请运行：
/opt/teradata/tdqgm/bin/restore.sh <backup_file> Enter public address for this manager instance [<public_address>]:
其中，<backup_file> 是备份 ZIP 文件的路径名称，类似于 ~/tdqgm-backup-2016-06-16.zip，<public_address> 是 Teradata QueryGrid 管理器系统的主机名或 IP 地址；例如︰test.mydomain.com 或 198.51.100.20。
结果（注意，出现提示时输入 y）：
A restore from backup removes all data previously saved on this manager instance and
all local manager services are restarted. This manager instance becomes a standalone cluster.
Other managers can join this instance using the join-cluster command.
