Symptoms

在以下条件适用的情况下，存储在 Data Domain 上的 Avamar 备份将失败：

  • 已执行到新 Avamar 的根到根迁移
  • Data Domain 未集成到原始系统中
  • 从原始系统迁移的客户端的备份失败。
  • 激活到新系统的新客户端可以成功备份到 Data Domain。

失败客户端备份日志文件中的示例错误：

avtar Info <7694>: Server(xxxxxx.xxxxx.com) not responding (possible network congestion?) (300 seconds)
avtar Error <5775>: Internal Error: backtree: bad response 4c8d1d4a37a917cd76137c9afd63a4de44b8b328 74 ADD_HASH_DATA=2 serial=74 seq=0 flags=R:N:0 kind=9 rsp=MSG_ERR_INVALID_PARAMETERS
avtar Info <5726>: Aborting backup due to error (3:EXC_HFSERROR)
avtar FATAL <5399>: Internal error, aborting
avtar Info <9772>: Starting graceful (staged) termination, error reported in nbackmain (wrap-up stage)

 

Cause

该文件中存储的信息与客户端上的哈希缓存中存储的信息以及 Avamar 网格上存储的相关对象之间存在冲突。

 

Resolution

  1. 从客户端（f_cache.dat 和 p_cache.dat）上的 var 目录中删除文件和哈希缓存。

  2. 重新运行到 Data Domain 的备份。

备份现在应该已经成功了。
