How To Back Up iPhone & iPad To a Computer When iTunes Is Gone?

I use iCloud for my backups but also use iTunes to back up to my computer. Will there still be a way to back up to my mac once iTunes is gone? I like the option of both just in case one fails. I have found that when I needed to restore a backup from iCloud it takes much longer than from the one on my mac via iTunes. I recently got a new phone & used iCloud & it took several hours to get everything on it.
