我有一個每天從一臺服務器恢復數據庫的過程。 它恢復了數據庫的數據庫備份文件，如果它找到TLog備份文件，它也會恢復它們。數據庫和日誌恢復作業失敗
該過程現在工作一段時間沒有問題。 今天，它失敗 錯誤消息：

你可以看到，它試圖恢復16.9，從凌晨1點，16.9從2AM日誌文件中，16.9從3AM日誌文件， 日誌文件，然後是23PM的日誌文件15.9，以及12AM的日誌文件16.9。
日誌的恢復順序被搞亂了。
我回頭看了一下這個工作的歷史，我們有大約3周的日常執行歷史。 在每個執行過程中，順序都是正確的。 例如：

所以，正確的順序是前一天晚上11點的，當前日，凌晨1點，2AM，和當天的凌晨3點的12AM。
所有日誌都存在於其共享文件夾目錄中。 一切看起來很正常。
你碰巧想到一個想法爲什麼這個工作失敗？
在此先感謝，
