要编写一个自动备份 SQL Server 数据库的脚本，可以使用 SQL Server Management Studio (SSMS) 或者 Transact-SQL (T-SQL) 脚本。以下是一个简单的 T-SQL 脚本示例，该脚本将数据库备份到指定的文件路径：

-- 设置要备份的数据库名称
DECLARE @DatabaseName NVARCHAR(100)
SET @DatabaseName = 'YourDatabaseName'

-- 执行备份
BACKUP DATABASE @DatabaseName
TO DISK = @BackupPath
WITH FORMAT, 

-- 如果存在相同名称的备份文件，使用 FORMAT 选项会覆盖旧文件
MEDIANAME = 'BackupMedianame',
NAME = 'BackupName';
-- 输出备份成功信息
PRINT 'Backup completed successfully.'
