I stood up a pair of QNAP NAS for both my parents and I, and encrypt-then-backup their photos/documents to my NAS, and vice-versa. RAID 5 or 6 keeps hardware failure at bay, and keeping them tucked away in our respective homes makes fire or flood irrelevent (for this).
QNAP or Asustor has standalone apps my parents can use as well. Without getting your parents involved, you could either pay for remote hosting for your off-site, or trade RAID space with a friend.
