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...
Assume that you are using Microsoft SQL Server 2016 and Microsoft SQL Server 2017. You enable Transparent Data Encryption (TDE) on your database, and then you back up the database by using compression. When you try to restore the database from this backup and verify the backup file...
T-SQL创建事务日志备份 使用T-SQL语句来创建事务日志的备份方法如下: USE Master GO BACKUP LOG [AdventureWorks2008R2] TO DISK = N'C:\temp\AdventureWorks2008R2_log_201711122201.trn' with compression,stats=1; GO BACKUP LOG [AdventureWorks2008R2] TO DISK = N'C:\temp\AdventureWorks2008R2_log_2017111...
Transact-SQL For a given backup, you can use either WITH NO_COMPRESSION or WITH COMPRESSION in a BACKUP statement. For a log shipping configuration, you can control the backup compression behavior of log backups by using sp_add_log_shipping_primary_databasesp_change_log_shipping_primary_data...
Following is a sample Transact-SQL statement to encrypt the backup file: SQL Copy BACKUP DATABASE [MYTestDB] TO DISK = N'C:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\Backup\MyTestDB.bak' WITH COMPRESSION, ENCRYPTION ( ALGORITHM = AES_256, SERVER CERTIFICATE = BackupEn...

在“备份策略”菜单中,选择是否启用“SQL 备份压缩” 。 默认已禁用此选项。 如果启用,SQL Server 会向 VDI 发送压缩的备份流。 Azure 备份将根据此控件的值,使用 COMPRESSION / NO_COMPRESSION 子句替代实例级别的默认值。 完成备份策略的编辑后,选择“确定”。 备注 每个日志备份都链接到上一个完整备份,以形成...
Backup Compression and Transparent Data Encryption (TDE) have been two immensely valuable and popular features for customers in SQL Server. In SQL Server 2016, backup compression was enabled for TDE-enabled databases, where if you backup a TDE-enabled database...
