Symptoms

升級至 NetWorker 19.11 後，NMC 資料庫備份失敗。

原則動作記錄中的錯誤： 
108179:savepsm: Replicating database contents to C:\Program Files\EMC NetWorker\Management\nmcdb_stage\pgdata...
108180:savepsm: Unable to execute C:\Program Files\EMC NetWorker\Management\GST\postgres_latest\bin\pg_basebackup.exe in order to copy the database
108181:savepsm: See 'C:\Program Files\EMC NetWorker\Management\GST\logs\pg_basebackup.log' for details

108180:savepsm: Unable to execute C:\Program Files\EMC NetWorker\Management\GST\postgres_latest\bin\pg_basebackup.exe in order to copy the database
108181:savepsm: See 'C:\Program Files\EMC NetWorker\Management\GST\logs\pg_basebackup.log' for details
C：\Program Files\EMC NetWorker\Management\GST\logs\pg_basebackup.log 中的錯誤： 
pg_basebackup: incompatible server version 12.18
pg_basebackup: removing data directory "C:\Program Files\EMC NetWorker\Management\nmcdb_stage\pgdata"

Cause

有了 NetWorker 19.11，Postgres 已更新至 12.18 版。然而， postgres_link 下面 C:\Program Files\EMC NetWorker\Management\GST 仍然連結到Postgres 11.21。

這是錯誤連結的範例：

 <SYMLINKD>     postgres_latest [C:\Program Files\EMC NetWorker\Management\GST\postgres\11.21]

Resolution

請遵循這些步驟以解決此問題：

1） 前往 C：\Program Files\EMC NetWorker\Management\GST。
2） 刪除連結postgres_latest。
3） 重新建立連結以指向 Postgres 12.18 資料夾。

mklink /D "C:\Program Files\EMC NetWorker\Management\GST\postgres_latest" "C:\Program Files\EMC NetWorker\Management\GST\postgres\12.18"
