Symptoms

適用於 Microsoft 的 NetWorker 模組 (NMM) 無法手動備份 Active Directory。   

  • 範例命令 - 此命令是從命令列執行
nsradsave -b "PoolName" -s ServerName  -D 9  -l full "DC=amer,DC=lan"

 

輸出範例 
 

C:\Program Files\EMC NetWorker\nsr\applogs>nsradsave -b dd1amerlan -s linux1 -l full "CN=users,DC=amer,DC=lan"

89613:(pid 3080): Unable to initialize SSL library: BSAFE FIPS library path was not set
200170:(pid 3080): unable to initialize multisubnet state: Authentication error; why = Client credential too weak
145072:(pid 3080): Unable to get port range from local nsrexecd: Failed to initialize ports using nsrexecd on dc.amer.lan: Authentication error; why = Client credential too weak
107092:(pid 3080):Version information for C:\Program Files\EMC NetWorker\nsr\bin\nsradsave.exe: Original file name: nsradsave.exe

53362:(pid 3080): Cannot start session with server linux1: Authentication error; why = Client credential too weak

Failed to initialize backup.
Authentication error; why = Client credential too weak

 

Cause

此問題的根本原因是用戶端啟動(手動)備份的已知限制。  

  • 當 NetWorker 伺服器和用戶端在 NSRLA「auth methods」中都有 nsrauth 時,就會發生這種情況,例如:
auth methods:  "0.0.0.0/0, nsrauth"
  • 如果 NetWorker 伺服器為 Linux 且僅使用 nsrauth,也會發生此情況

 

Resolution

此限制記錄在 NMM 管理指南中。

支援的活動目錄備份和恢復類型和配置

NMM 支援:
● 粒度備份,以完整和增量級別執行。
● 粒度恢復,即單個 Active Directory 物件或物件屬性的恢復。

注意:若要備份和還原檔案系統,以及還原系統狀態備份,請使用 NetWorker。

注意:為了成功執行用戶端啟動的備份,請將 NMM 用戶端中的驗證方法變更為驗證方法:

0.0.0.0/0,nsrauth/oldauth。
