替换<DatabaseName>为对应数据库名-- 备份数据库的事务日志到Null设备,即不保存BACKUP LOG [<DatabaseName>]TODISK ='NUL';-- 备份数据库的事务日志到/var/opt/mssql/data/Test.trn文件BACKUP LOG [<DatabaseName>]TODISK = '/var/opt/mssql/data/Test.trn';...
在SQL Server20908里创建一份被压缩了的备份很简单——你能用的T-SQL语言或者是仅包括COMPRESSION这个词的WITH子句。如果使用SQL Server Management Studio,就只需要在备份数据库会话里Options选择键上选择“压缩备份”这一选项。以下就是备份AdventureWorks数据库的示例。 压缩备份 AI检测代码解析 BACKUP DATABASE [Advent...
BACKUP DATABASE TO URL WITH FILE_SNAPSHOT 和 BACKUP LOG TO URL WITH FILE_SNAPSHOT 之间的唯一区别是后者会截断事务日志,而前者不会。 借助 SQL Server 快照备份,在完成 SQL Server 建立备份链时所需的初始完整备份之后,只需单个事务日志备份即可将数据库还原到事务日志备份的时间点。 此外,只需两次事务日志...
