升级安装VMware vCenter 6.7 Update 2后，Veeam备份失败

shengji##### 1. 升级VCENTER到6.7U2后，VEEAM开始不正常了，不能备份，报错全是——未将对象引用设置到对象的实例。

2. 这个其实VEEAM的官方团队已经注意到，并且给出了解决方案：

Solution
Create the following registry value under HKLM\SOFTWARE\Veeam\Veeam Backup and Replication key on the Veeam Backup and Replication server:

Location: HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Backup and Replication
Key type: Multi-String Value (REG_MULTI_SZ)
Value: VMwareOverrideApiVersion
Data: 6.7.2=6.7

3. 重新启动 Veeam Backup Service

4. 备份正常
