[Dar-discussions] Differential backup based on catalogue file

[T o n g <mli...@ya...>]

Hi, 

I want to do a differential backup based on a given catalogue
file. I think it should work, but test shows otherwise [1]:

I.e., I see that a file is already backed up, and show up in the
catalogue file, but dar still wants to back it up, even everything
seems to be the same. 

What's happening? How can I do further investigation?

Thanks
