如何在 SQL 中使用存储过程备份数据库？

Question

我正在尝试创建一个备份数据库的存储过程，但是每当我执行它时，我要备份到的文件夹仍然是空的。

这是我的存储过程：

USE [HarvestMan_SoutheskFarm_03_05_22]
GO

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

-- =============================================
-- Author:      Will Sewell
-- Create date: 03-05-2022
-- Description: Procedure to back up a database
-- =============================================

ALTER PROCEDURE [dbo].[BackupDatabases] 
    @name VARCHAR(MAX) = 'HarvestMan_SoutheskFarm_03_05_22' -- DB NAME TO CREATE BACKUP
AS
BEGIN
    DECLARE @path VARCHAR(256) -- path of backup files
    DECLARE @fileName VARCHAR(256) -- filename for backup
    DECLARE @fileDate VARCHAR(20) -- used for file name

    SET @path = 'C:\Users\will.sewell\Documents\Database_Test'

    -- specify filename format
    SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),112)

    BEGIN
        SET @fileName = @path + @name + '_' + @fileDate + '.BAK'

        BACKUP DATABASE @name TO DISK = @fileName
    END
END

我试过更改正在写入的驱动器。

我已经复制并粘贴了我要备份的数据库名称，以确保没有拼写错误。

我假设这可能是权限问题或文件夹中的可见文件。

当我执行存储过程时，我得到：

Processed 24472 pages for database 'HarvestMan_SoutheskFarm_03_05_22', file 'HarvestMan_dat' on file 2.

Processed 1 pages for database 'HarvestMan_SoutheskFarm_03_05_22', file 'HarvestMan_log' on file 2. BACKUP DATABASE successfully processed 24473 pages in 5.039 seconds (37.941 MB/sec).

create proc SqlDBBackup  
as  
begin  
    declare @path varchar(1000);  
    set @path='D:\Backup\SampleDBTest3' + CONVERT(CHAR(10),
        GETDATE(),
        121) + '.bak';  
    BACKUP DATABASE SampleDBTest to DISK=@path;  
end
