NBU catalog报错处理办法

现象描述

• 环境说明：

  • NBU 7.7.3 Master Server
  • Windows Server 2008R2 x64操作系统

• NBU Master Server备份catalog一直报错，错误代码2

  • status详细信息如下：

    none of the requested files were backed up  (2)

• 检查系统进程 已运行700+进程，怀疑进程过多导致Master hang死

尝试解决

第一次

根据报错信息，定位C:\Program Files\Veritas\NetBackupDB\staging目录，删除该目录文件，重启服务后手动发起catalog备份，成功。

第二天再发起再次报错，非长久之计。

第二次

报case，协助工程师收集cab。

对于Windows:

C:\windows\system32\chcp 437
C:\Program Files\Veritas\netbackup\bin\support\nbsu -use_reg_cmd 64 (for 64bit)

执行nbsu到network service卡住，询问工程师终止命令，执行如下：

C:\Program Files\Veritas\netbackup\bin\support\nbsu -c -use_reg_cmd 64

产生LOG 的路径:

C:\Program Files\Veritas\netbackup\bin\support\output\nbsu (后缀名是cab)

后操作如下

1. Delete the outstanding nbtelemetry.exe processes in task manager, this in turn stopped the nbtelesched.exe processes.

   tasklist
   taskkill /im nbtelemetry.exe /f

   强制结束进程

2. Once these were deleted, went into directory Program files\Veritas\Netbackup\bin
   Renamed nbtelemetry.exe and nbtelesched.exe to nbtelemetry.exe.old and nbtelesched.exe.old.

   若无法重命名，重启机器再修改

3. Run regedit and go to the following key
   HKLM(HKEY_LOCAL_MACHINE)\Software\VERITAS\NetBackup\CurrentVersion\Config\TELEMETRY_UPLOAD
   Changed TELEMETRY_UPLOAD from YES to NO under the registry editor.

   再次发起catalog备份，正常。

观察几天，进程数不超过100，且备份catalog不报错.

总结

NBU catalog

NetBackup自身有一索引数据库，主要记录每次备份的相关信息。比如从哪个Client备
份的，保留多长时间等。
