Question

我有一个mssql脚本，我想将其用于每日完整备份和日志备份，我无法理解如何添加CHECKSUM值来使其正常工作，任何人都可以帮助我解决这个问题：

DECLARE @name VARCHAR(50) -- database name   
DECLARE @path VARCHAR(256) -- path for backup files   
DECLARE @fileName VARCHAR(256) -- filename for backup   
DECLARE @fileDate VARCHAR(20) -- used for file name  

SET @path = 'C:\Backup\'   

SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),112)  
   + '_'  
   + REPLACE(CONVERT(VARCHAR(20),GETDATE(),108),':','') 

DECLARE db_cursor CURSOR FOR   
SELECT name  
FROM master.dbo.sysdatabases  
WHERE name NOT IN ('master','model','msdb','tempdb')  
   AND DATABASEPROPERTYEX(name, 'Recovery') IN ('FULL','BULK_LOGGED') 

OPEN db_cursor    
FETCH NEXT FROM db_cursor INTO @name    

WHILE @@FETCH_STATUS = 0    
BEGIN    
       SET @fileName = @path + @name + '_' + @fileDate + '.TRN'   
       BACKUP LOG @name TO DISK = @fileName   

       FETCH NEXT FROM db_cursor INTO @name    
END    

CLOSE db_cursor    
DEALLOCATE db_cursor

Answer 1

您的命令应如下所示：

BACKUP LOG @name TO DISK = @fileName with checksum

您可以在以下Enable or Disable Backup Checksums During Backup or Restore (SQL Server)和此处的BACKUP (Transact-SQL)下找到此语法 错误管理选项

Answer 2

我认为您真正想要的是一个RESTORE VERIFYONLY，它将检查已创建的备份文件的状态。

RESTORE VERIFYONLY FROM DISK = @fileName;

如何在日志备份脚本中添加校验和？
