My cloud home 4TB time machine max space

hello all,

im new here and I just buy the my cloud home 4 TB to used it for my Time Machine backup and other documents to storage.

no I saw a older video on youtube that you can tell the harddisk how many space there is aloud that de Time Machine back up can use. now I have installed the nas I saw that the interface is diverted then before. and I can’t find it where I can say how many space he can have.

and if its not a option any more can u make 2 partition on the harddisk so that I can use 1Tb voor Time Machine and the other 3 GB for free space.

I hope someone of you all here can help me and gif me the answers I look for.

thanks for the help an replay’s
