部份差異備份包含唯讀檔案群組 '%1'，因為其中一或多個檔案自進行基底部份備份後並無基底備份。建議進行另一個檔案群組備份 '%2'，並進行新的部份備份。

The partial differential backup is including readonly filegroup '%1' because one or more of its files does not have a base backup since the base partial backup was made. It is recommended that a separate filegroup backup of '%2' is made and a new partial backup taken.
