虚拟桌面基础架构 （VDI） 的 VMware 映像备份失败，显示 avvcbimage 错误 <0000>：[IMG0009] Create Snapshot：快照创建或快照前/后脚本失败。

/usr/local/avamarclient/var/vmimagew.log中的错误如下所示： 
avvcbimage FATAL <0000>: [IMG0002] The datastore information from VMX '[3PAR11_CITRIX02] Virtualmachine/Virtualmachine.vmx' will not permit a restore or backup.
avvcbimage Info <9772>: Starting graceful (staged) termination, Too many pre-existing snapshots on the datastore will not permit a restore or backup. (wrap-up stage)

Cause

代理 数据存储区检查 功能已在 avvcbimageAll.cmd 中启用。不建议将此功能用于使用 VDI 的 Avamar 映像备份。

要验证上述功能是否已启用，请在代理服务器上运行以下命令：
  
cat /usr/local/avamarclient/var/avvcbimageAll.cmd | grep -i skip_datastore_check

If enabled, The output should be as below:
 

cat /usr/local/avamarclient/var/avvcbimageAll.cmd | grep -i skip_datastore_check
#--skip_datastore_check=false


 

Resolution

对于此问题，我们有两种可能的解决方法：
  • 在代理服务器上 avvcbimageAll.cmd 编辑。取消注释 skip_datastore_check行并将其值设置为 true。
cat /usr/local/avamarclient/var/avvcbimageAll.cmd | grep -i skip_datastore_check
--skip_datastore_check=true
  • 或者为 VDI 备份创建特定数据集并添加以下标记：
[avvcbimage]skip_datastore_check=true
