注意:如果您沒有上述儲存集,您就無法還原 NMC,唯一的選項就是 將其重新安裝為全新例項。
2) 在 NMC 伺服器上開啟管理/根命令提示字元,停止 NMC GSTD 服務 (如果執行中):
Windows: net stop gstd
Linux: systemctl stop gst
注意: 使用 工作清單/工作管理員或 ps 命令來確認 gstd 服務已停止
3) 使用 cd 命令瀏覽至 NMC 的安裝 bin 目錄。檢查以確保 recoverpsm 命令列在此目錄內。此命令將用於復原 NMC 資料庫。
Windows:[NMC 安裝目錄\管理\GST\bin
Linux:/opt/lgtonmc/bin
4) 在 NMC 伺服器上執行 recoverpsm 命令:
Options:
-c 用戶端名稱 |
指定來源 NMC 伺服器的名稱。有關更多詳細資訊,請參閱還原。 |
d 目的地 |
指定 recoverpsm 將 NMC 資料庫復原的目錄。使用此選項時,必須手動將資料庫檔從目標目錄複製到為 NMC 伺服器定義的資料庫目錄。確保在複製完成後保留對資料庫檔和憑據檔的相同擁有權和許可權。 |
f |
使用此選項可在開始恢復操作之前刪除資料庫目錄中存在的目前資料庫檔。 |
h |
顯示有關 recoverpsm 命令的使用資訊。 |
O |
使用此選項可省略資料庫認證檔案的復原作業。只有在憑據檔仍然存在並且您不想使用恢復中的憑據檔的極少數情況下,才使用此選項。 |
p 密碼片語 |
使用此選項可在嘗試恢復 AES 加密資料庫檔時指定其他密碼短語。如需更多詳細資訊,請參閱 recover(1m)。 |
s 伺服器 |
指定執行 NMC 資料庫備份的 NetWorker 伺服器名稱。 |
時間 |
使用此選項可復原資料庫,作為指定的日期,以 nsrgetdate 格式。 |
暫存目錄 |
指定備份操作使用的暫存目錄。對於自動備份,請指定存儲集名稱 |
