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 BACKUP DATABASE [AdventureWorks] TO DI...
通过在BACKUPTransact-SQL 命令中指定WITH COMPRESSION (ALGORITHM = ZSTD)选项以进行特定备份。 通过将备份压缩算法服务器配置选项设置为 3。 对于使用该WITH COMPRESSION选项的所有备份,此选项将默认备份压缩算法设置为 ZSTD。 备注 ZSTD 算法目前为预览版,仅在 SQL Server 2025 (17.x) 预览版中可用。

If the backup command is specified WITH COMPRESSION or the backup compression default server configuration is set to 1, MAXTRANSFERSIZE will automatically be increased to 128K to enable the optimized algorithm. If MAXTRANSFERSIZE is specified on the backup command with a value > 64K, the provided...
Backup Compression in SQL2008 performs very well and it is easy to use. You could either use “With Compression” along with the “Backup” command or simply enable default backup compression through sp_configure by setting ‘backup compression default’ value to 1. It ...
