Backing up multiple user data

[Janina Sajka]

Not exactly. rsync will do as you say, but only if those users also
exist on the target system. It cannot create new user accounts, and
shouldn't be able to, either.

Now that I've strayed into 'shoulds,'  I suppose we could posit the
notion of rsync for passwd and shadow, but this just too wacky because
it's dangerous.
