Add date to SQL database backup filename

Question

I'm using the below to backup a db from a SQL job. Can someone tell me how to add the current date to the output filename? Preferably in YYYYMMDD format.

BACKUP DATABASE [myDB] TO  DISK = N'\\myPath\myDB.bak' WITH NOFORMAT, INIT,  NAME = N'myDB', SKIP, REWIND, NOUNLOAD,  STATS = 10
GO

Thanks!

Answer 1

DECLARE @MyFileName varchar(50)

SELECT @MyFileName = (SELECT '\\ServerToSave\Path\MyDB_' + convert(varchar(50),GetDate(),112) + '.bak') 

BACKUP DATABASE [myDB] TO DISK=@MyFileName ...

I love how all the other posters stole my code ?

Just convert it I just tested and it worked...

Answer 2

Try this.

DECLARE @MyFileName varchar(50)
SELECT '\\ServerToSave\Path\MyDB_' + convert(nvarchar(20),GetDate(),112) + '.bak'
BACKUP DATABASE [myDB] TO DISK=@MyFileName ...

The 112 in the Convert gives you the YYYYMMDD format

Answer 3

Use the following

DECLARE @BackupFileName varchar(20)

SELECT @BackupFileName = '\\ServerName\SharedFolder\DatabaseName_' + CONVERT (VarChar, GetDate(), 112) + '.bak'

BACKUP DATABASE [myDB] TO  DISK = @BackupFileName WITH NOFORMAT, INIT,  NAME = N'myDB', SKIP, REWIND, NOUNLOAD,  STATS = 10
