They certainly are not harder than installing early Debian releases (as
I remember it from around 20 years ago, and should not be hard for
anyone building a backup system and server. Installation as an
additional file system should not be notably different from installing a
file system package from main, except for the notice the GPL
incompatibility notice that will pop up during installation.

I would recommend installing from buster-backports to get the current
openzfs release which includes improvements (notably native encryption)
as well as fixes.

Two questions:

    * Most of my backup will be done from a Wheezy system -- can I install ZFS
on Wheezy?

I do not see any ZFS packages for Wheezy:

The simplest answer would be to install Buster and then install 'zfs-dkms' (either Stable or backport, depending upon preference).


    * If I plug the USB drive into another machine without ZFS installed --
hmm, well I guess I'd have to install ZFS to use the drive?

Yes.
