I´m sure that i had multipolygone objects....

I don´t understand it by myself because the geometrie collum should be the same as it was in the original table ( why should there any converting?!).

But I have to admit that I have no chance to check this. The original dataset is lost :(

thanks a lot for answering, I think the only thing I can do is to recreate the multipolygones by hand. After this I´ll try the restore case again and post the behavior of the backup....

best wishes
