--段落还原：数据库损坏范围比较大，跨多个数据文件甚至跨文件组的时候，我们不得不恢复整个数据库。
--这时如果数据库特别大，数据库恢复时间将会很长。但我们可以使用SQL Server提供的段落还原，来逐步恢复数据库。
--首先备份尾日志：
BACKUP LOG [AdventureWorks] TO DISK =N'D:\BACKUP_TEST\LOG_BACK_TAIL.trn' WITH NO_TRUNCATE ,NORECOVERY,COMPRESSION,STATS=10
--部分还原主文件组PRIMARY：
RESTORE DATABASE [AdventureWorks] FILEGROUP=N'PRIMARY' FROM DISK=N'D:\BACKUP_TEST\AD_FULL.bak' WITH PARTIAL,NORECOVERY,STATS=10
--还原副文件组MST：
RESTORE DATABASE [AdventureWorks] FILEGROUP=N'MST' FROM DISK=N'D:\BACKUP_TEST\AD_FULL.bak' WITH NORECOVERY,STATS=10
--依次还原日志：
RESTORE LOG [AdventureWorks] FROM DISK=N'D:\BACKUP_TEST\LOG_BACK_1.TRN' WITH NORECOVERY,STATS=10
RESTORE LOG [AdventureWorks] FROM DISK=N'D:\BACKUP_TEST\LOG_BACK_2.TRN' WITH NORECOVERY,STATS=10
--还原尾日志并恢复
RESTORE LOG [AdventureWorks] FROM DISK=N'D:\BACKUP_TEST\LOG_BACK_TAIL.TRN' WITH RECOVERY,STATS=10
--此时AdventureWorks数据库中位于PRIMARY和MST文件组中的文件已经可以访问。
--但是位于其他文件组如：TRN文件组中的表还不能访问。
--消息 8653，级别 16，状态 1，第 2 行
--查询处理器无法为表或视图“****”生成计划，因为该表驻留在不处于联机状态的文件组中。

--接下来还原副文件组TRN：
RESTORE DATABASE [AdventureWorks] FILEGROUP=N'TRN' FROM DISK=N'D:\BACKUP_TEST\AD_FULL.bak' WITH NORECOVERY,STATS=10
--如果数据库不是企业版，以上还原将会提示“尚未备份数据库 "AdventureWorks" 的日志尾部。”
--需要再次备份一次日志尾部，意味着还原副文件组TRN的时候整个数据库都处于正在还原状态。所以对于非企业版而言，只能离线段落还原，个人觉得意义不是很大......
--依次还原日志：
RESTORE LOG [AdventureWorks] FROM DISK=N'D:\BACKUP_TEST\LOG_BACK_1.TRN' WITH NORECOVERY,STATS=10
RESTORE LOG [AdventureWorks] FROM DISK=N'D:\BACKUP_TEST\LOG_BACK_2.TRN' WITH NORECOVERY,STATS=10
--还原尾日志并恢复
RESTORE LOG [AdventureWorks] FROM DISK=N'D:\BACKUP_TEST\LOG_BACK_TAIL.TRN' WITH RECOVERY,STATS=10
--此时位于副文件组TRN中的表已经可以访问了。
--段落还原全部完成
