    Can Time Machine store its backup simultaneously to multiple drives? How is it possible that i might use more than one drive to store a TM backup?

    By saying alternate you dont mean anything like RAID... correct? Suppose i have 2 drives in which TM backup files are stored. If one of those 2 drives fails -God forbid- the files that will be in the working drive will have the ability to be opened and used because they are unique files... correct?

    Also... in Sierra, have there been any improvements to the TM app when compared to Yosemite TM version?

    Yes exactly. It is nothing like RAID. It backs up to drive one one hour, then drive two the second hour, and so on. So you always have two complete TM backups.

    Hmm that is not what i understood. So you have 2 identical backups! I thought that files are placed in multiple drives in order to manage a lot of files.
    Suppose i have a 4TB drive i wish to backup using TM. Can choose 2 x 2TB drives (as my multiple choice) so that TM can backup the files there? (do i make sense?)

    No... it will not span one backup over multiple drives like that. It will only do the same backup on two drives. So if you have 4TB of data on a drive, you will need at least a 4TB drive for a TM backup. Or two 4TB drives for two TM backups.
