Currently, we have tasks with Windows Task Scheduler that run each night. The tasks pump data from one database to another. Data is also transformed in this process. It is not a one to one copy. The date interval is one month back in time. All this works fine.
But now a new requirement arrives. Once per year we should pump data one year back in time. Preferbly on a Sunday but I saw that Task Scheduler can fix that.
But it is double work as normal nightly pumping also happens. How can I avoid this as the pumping is a demanding process ? The datapump is inhouse software so we have complete control of it.
So it would be great if I could make a normal schedule with a list of exception dates to stop the trigger.
