HI AlexSorry, I said this wrong, when making a snapshot a copy is first made to the primary storage, _not management disk_, and once done its moved to the secondary storage and then deleted from primary. This is explained here: https://github.com/apache/cloudstack/issues/6836#issuecomment-1285524454

all snapshots make a local copy to the management server disk before sending it to the secondary storage locations, yes.What exactly do you mean by that?

Async or not. But yes, I believe that is the case. However, when async is enabled you get to use and work on other tasks with the management server, while it does the snapshot process in the background. Whereas having async disabled, you are restricted from doing other task on the management server until the snapshot process completes, that's how I understand it.

On a host that has multiple primary storages (e.g. NFS and some other storage over iSCSI) but no local disks are used, what is considered as 'locally'? Also, by "storage location" do you mean the secondary storage?

This helps with server resource usage. But see attached screenshot for a detailed answer.
