SQL 2008

Is there a way I can delete old backups stored on my local hard drive.

I currently have a folder on the server that I backup to.   I then back this folder up over night.
I want to have say a weeks worth of the backup files on the hard drive and then remove anything over 7 days.

Any advise?

You can add a cleanup task to your maintenance plan that will delete old backups

--The code below does just that and all you need is to addapt it to your folder/file names. I suggest use the PRINT commands until you get exactly what you need.

--delete old weeky bkps

---check if zip file exists on C:\SQL_BACKUP then delete old files from G:
set nocount on
declare @crtdate varchar(255)
declare @sqlcmd varchar(4000)

set  @crtdate = CAST(YEAR(getdate()) AS VARCHAR(4))+ '_' +
case when MONTH(getdate()) < 10
      then '0'+CAST(MONTH(getdate()) AS VARCHAR(2))
      else CAST(MONTH(getdate()) AS VARCHAR(2))
end + '_' +
case when DAY(getdate()) < 10
      then '0'+CAST(DAY(getdate()) AS VARCHAR(2))
      else CAST(DAY(getdate()) AS VARCHAR(2))
--print @crtdate

--test command
--set @sqlcmd = 'EXEC xp_cmdshell ''dir "C:\SQL_BACKUP\SQL_BACKUP_'+@crtdate+'.zip"'''
--print (@sqlcmd)

create table #t (c1 text)
set @sqlcmd = 'insert into #t exec xp_cmdshell ''dir I:\SQL_BACKUP\SQL_BACKUP_'+@crtdate+'.zip'''
--print (@sqlcmd)
exec (@sqlcmd)
--select * from #t
--select * from #t where c1 like ''

if exists (select * from #t where c1 like '')
      -- delete all old backup files from G:\sql_backup directory
      declare @source varchar(255)

      set @source = '*_backup_' + CAST(YEAR(getdate()-7) AS VARCHAR(4))+ '_' +
      case when MONTH(getdate()-7) < 10
            then '0'+CAST(MONTH(getdate()-7) AS VARCHAR(2))
            else CAST(MONTH(getdate()-7) AS VARCHAR(2))
      end + '_' +
      case when DAY(getdate()-7) < 10
            then '0'+CAST(DAY(getdate()-7) AS VARCHAR(2))
            else CAST(DAY(getdate()-7) AS VARCHAR(2))

      --test command
      set @sqlcmd = 'EXEC xp_cmdshell ''dir G:\SQL_BACKUP\'+@source
      exec (@sqlcmd)
      --print @sqlcmd
      set @sqlcmd = 'EXEC xp_cmdshell ''del G:\SQL_BACKUP\'+@source
      exec (@sqlcmd)
      --print @sqlcmd

drop table #t
