最近很郁闷遇到好多错误

环境：master  A:windows2003      NBU6.0 MP4 SERVER     接了个小的阵列
      client     B:solaris 10 .5.1     NBU CLIENT  sybase  option           安装了 sybase
         容灾服务器：C  ：solaris 10 5.1  NBU CLIENT        sybase  option     sybase 容灾库
  
   工作原理    A备份B的sybase 形成image 文件存放到A的阵列里来  ，在C的机器上做计划任务定时恢复image文件到容灾库上   使容灾库上的sybase和他本地的sybase数据同步  

经过测试   脚本和方案都可行并且已经运行2个月 

现在出错问题如下  ：能够正常备份 远程本地的sybase库  ！但是在恢复到容灾库上时候出错  下面是他们详细的错误

NBU  detail  :

在容灾库上看到sybase的日志    如下

我判断的结论 1，是sybase 库进程死  ！重启备份库   问题依然
             2，认为是备份没成功 所以手动备份了一次  成功    但是恢复还是失败  

求助 ：请问是什么问题引起的  ？ 该怎么解决    ？   

请注意是恢复失败 ！！不要怀疑脚本  ！他是正确的 ！！
