Cause
此问题是由于嵌入在 Avamar 19.3.100-149 WC 和 NC 客户端中的 DD Boost 库版本 7.2.0.5 内部版本654364的兼容性问题导致的。当这些客户端连接到运行 DD OS 7.2.0.40-664052 或更高版本的 Data Domain 系统时,会出现此问题。
Resolution
将所有受影响的 Avamar WC 和 NC 客户端升级到 Avamar 版本 19.4 或更高版本。
完成以下步骤:
- 下载适用于相应操作系统的 Avamar 19.4 Client 软件。
- 在所有受影响的系统上升级 Avamar Client。
- 验证客户端注册是否成功,并连接到 Data Domain 系统。
- 运行测试备份以确认正常运行。
对于具有受影响 DD OS 版本的 Avamar 19.3.100-149 客户端,没有任何配置更改或解决方法可用。
Additional Information
- 使用嵌入式 DD Boost 库时,Avamar 19.3.100-149 客户端与 Data Domain OS 7.2.0.40-664052 或更高版本不兼容。
- 戴尔建议保留兼容的 Avamar Client、DD Boost 和 Data Domain OS 版本,如《Avamar 兼容性指南》中所述。
- 此问题会影响使用 Data Domain Boost 的 Avamar Windows 客户端和非 Windows 客户端。
