Problem with time-machine

Hey guys,

Since yesterday I‘ve got an i7-9700k, designare z390, 5700xt, 2x nvme (Windows and macos) hackintosh up and running.

So far everything works - except time machine. I have the strange behavior when setup and start my backup to may attached Sinologie nas , that the backup will abort with the message that my free space on the nas is not enough .... it would need 4tb space.

My nvme in the hackintosh is only 1tb big and I thin not even 5% is used so far.

When going the extra options I see that my attached 500gb, 1tb, and the other 1tb nvme for Windows are in the exceptions list - and the expected size of the backup there is shown by around 65gb.

Nevertheless it won’t work .... any suggestions to this strange behavior ?

Thanks guys
