Db full backup name changing

Posted on 2006-07-20

I have the following procedure running automatically to execute fll backups of a MS-SQL 2005 DB.

DECLARE      @return_value int

EXEC      @return_value = [dbo].[BackupDb] @DB = N'mydbname',
            @ImagePath = N'd:\dbbackups\',
            @ImageFileName = N'mydbnamefull.bak',
            @IsDifferential = 0

SELECT      'Return Value' = @return_value

GO

Is there any way this procedure can change the name of the .bak file to a different name everytime it runs. Let's say adding the date to the name?
Currently, everytime the procedure runs, it replaces the file with the new one. I'd like to keep the old files all the time.

Another option could be adding "something" to the procedure to create a new folder (with new name) everytime and store the .bak file there.

Any way to run this procedure without replacing the previous .bk file?

Hi,

When you assign the name, replace

@ImageFileName = N'mydbnamefull.bak',

with

@ImageFileName = N'mydbnamefull-' + convert(varchar(255), getdate(), 112) + right('00' + cast(datepart(hh, getdate()) as varchar(2)), 2) + right('00' + cast(datepart(mm, getdate()) as varchar(2)), 2) + right('00' + cast(datepart(ss, getdate()) as varchar(2)), 2)+ '.bak'


This will give you a file name that is unique, in the form

mydbnamefull-yyyymmddhhmmss.bak

which should be pretty unique

Hope this helps.

Regards,

Lee

Hi,

On reflection there is always

@ImageFileName = N'mydbnamefull' + replace(replace(replace(replace(convert(varchar,getdate(),121), '-', ''), ' ', ''), ':', ''), '.', '') + '.bak'

Does the same as what I did earlier, but the date format is always numerical which makes it easier searching on a directory listing for the latest as it will always be listed at the bottom if you list things by name. This is because the resultant number is an ever incrementing number.

Regards,

Lee

I'm getting an error (Incorrect syntax near '+'.) when I run  ANY of the solutions stated above.
Is it because I have the following defined in the store procedure?  I have very basic knowledge of this.

--Stored Proc Parameters
@ImageFileName NVARCHAR(100),
0

All codes are working fine ..

declare @ImageFileName nvarchar(100)
SET @ImageFileName = N'mydbnamefull'+REPLACE(REPLACE(CONVERT(varchar,getdate(),113),':',''),' ','')+'.bak'
SELECT @ImageFileName
SELECT @ImageFileName = N'mydbnamefull' + replace(replace(replace(replace(convert(varchar,getdate(),121), '-', ''), ' ', ''), ':', ''), '.', '') + '.bak'
SELECT @ImageFileName
