As the title eluded to! I had a scheduled backup fail today using TI 2009. My first thoughts were "oh dear what's happened here then" as the schedules have worked like clockwork since I installed 2009. The folder where the scheduler backs up to is on my Maxtor external drive and is used only for backups. When I looked on the Maxtor to see if I could see anything wrong I had the shock of my life - the folder along with all it's contents (three weeks worth of backups) was gone. How on earth can this have happened? The folder was two large to have been accidentally deleted - one always get the message "this file is to large for the recycle bin are you sure you want to permanently delete it" I think I would have remembered had I received any such warning. The wife never ever touches the external drive and would not have deleted anything in any event. Short of our dog using the PC and deleting the folder the whole thing is a complete mystery. Even if I had the "delete old archives" box ticked (which it isn't) this would not have deleted the folder. Can anyone shed any light on how this folder can have gone missing? I am running Vista by the way and a complete search of all drives has revealed nothing. Losing this folder isn't the end of the world as I have other copies of the backups kept on the internal slave drive, it's just that I do hate mysteries.
