SQL服務器完整備份作業正在跳過數據庫

Question

我有一個月度作業在我的SQL服務器上運行。

• 它將所有聯機數據庫備份到位置「\ Backupserver \ e $ \ MonthEndBackups \」。

• 運行作業的USP下面這樣：EXEC [usp_dba_BackupDatabases] 3 （http://screencast.com/t/l7IS5TZK）

• 它運行在每月的最後一天。

我們的數據庫分散在多個服務器上，這項工作在這些服務器上運行，這用於工作。

我們將所有數據庫合併到同一臺服務器上（同一個SQL實例），並且此作業似乎沒有備份所有數據庫。我不知道爲什麼？我的作業在發生故障時發出通知（電子郵件）並寫入日誌文件。

但沒有失敗，所以沒有什麼是對日誌和沒有電子郵件通知顯示。

我知道它沒有工作，因爲我沒有看到文件夾中的完整備份。

這裏是計劃設置：

可能是什麼回事？我在沒有備份的數據庫中看不到任何模式。有大型數據庫正在備份。

任何人都可以想到爲什麼會發生這種情況嗎？有什麼辦法來解決這個問題嗎？

嘗試使用下面的選項（固定有可能打破當前的環和also break sp_MSforeachdb的選項，因爲我已經證明here和here和corrected here）：

DECLARE c CURSOR LOCAL FAST_FORWARD FOR 
-----------------^^^^^^^^^^^^^^^^^^ 

... 

WHILE @@FETCH_STATUS <> -1 
---------------------^^^^^ 

此外，please, please, please stop declaring VARCHAR without length。
