use master
declare @DbName varchar(60)
declare @BackSql varchar(1000)
declare myCursor cursor for
 SELECT [name] FROM SYSDATABASES
 where [name] not in ('master','model','msdb','tempdb')
 order by [name]
open myCursor
fetch next from myCursor into @DbName
while(@@FETCH_STATUS = 0)
 begin
  if datename(weekday, getdate())='星期三'  --每周三覆蓋上周三的
   begin
    select @BackSql='Backup DATABASE ['+@DbName+'] to disk=''E:\DbBackUp\'+@DbName+'星期三.bak'' with format'

    select @BackSql='Backup DATABASE ['+@DbName+'] to disk=''E:\DbBackUp\'+@DbName+'AutoBack.bak'' with format'
   end
  exec(@BackSql)
  fetch next from myCursor into @DbName
