Workaround 

RMAN 備份時出現無法建立檔案 (backupset), 不外乎下三種原因
1. 磁碟空間滿了
2. 目錄名稱不對
3. 網路磁碟機

實際連線至客戶端檢測, Y: disk 果然是網路磁碟機, 而服務裡的 oracle service 是由 Localsystem 啟動
參考 Doc ID 145843.1 , How to Configure RMAN to Write to Shared Drives on Windows NT/2000/2003
需將服務啟動帳號改為 administrator (或 domain admin, 如果有 domain)

修改完成後需重啟服務
