Ok , now i have an little Problem .
I create an new Media Pool , named it "December Backups" , i moved all tapes from my December Weekly and Monthly Media Pools in this new Pool . Then i deleted the December Weekly and Monthly Pools .
But now in the new Pool the Tapes looses her original Media Set Information !!!!! Very Bad . I thin the Media Pool Optin is at the Moment not the "yellow of the Egg"
A little bit more Options to organize the Media Pools will be good in the future .
Perhaps , that you have an checkbox where you can say that when you move tapes from one Mediapool to antoher , the original Media Set Information should remain .
Now i have an Media Pool with many Offline Tapes and i dont know to which MediaSet originally belongs to . Inventory is only possible for Online Tapes .
