To apply logged changes to the data in a roll forward set to bring the data forward in time 由于存储聚合数据而引起的多维结构（例如多维数据集）大小的指数增长。
Is the process of redoing logged changes to the data in the roll forward set to bring the data forward in time ）是指重做对前滚集中的数据记录的更改以使数据及时前滚的过程。
The oldest file or page in the roll forward set determines the starting point for the next phase : redo roll forward 前滚集中最早的文件或页将决定下一阶段（重做，即前滚）的起点。
If a restore statement specifies filegroups , files , or pages , only these items are included in the roll forward set 如果restore语句指定了文件组、文件或页，则前滚集中将仅包括这些项。
If the whole roll forward set is consistent with the database , recovery is performed , and the database can be brought online 如果将数据库恢复到前一个时间点并从该点开始使用数据库，则将创建新的恢复路径。
A roll forward set is defined by restoring one or more full backups , such as a database or partial backup or a set of file backups 前滚集定义为包括一个或多个数据备份（完整备份、部分备份或文件备份）的一系列还原操作。
If the roll forward set has not been rolled forward far enough to be consistent with the database and recovery is specified , the database engine issues an error 如果前滚集尚未前滚到与数据库保持一致的地步，并且指定了recovery ，则数据库引擎将发出错误。

In these cases , the database engine issues an informational message stating that the roll forward set can now be recovered by sing the recovery option 还原数据库后，数据库引擎通常会防止意外覆盖其他数据库。默认情况下，如果出现下列情况，还原操作将失败：
However , read - only files that are consistent with the database can be added to the roll forward set without repeating any of the roll forward ; for more information , see 但是，可以将与数据库一致的只读文件添加到前滚集中，无须重复任何前滚；有关详细信息，请参阅
