As suggested by @daanrademaker, @petrescatraian, and @thomas I tryed out both @Zeitkapsel and @pixelunion as options for my photo backup.
Zeitkapsl looks and works good, but it lacks the ability to cast to my TV and is a bit too expensive for me.
Pixelunion is really good, have decent editing capabilities and I would happily recommend it to others, but the lack of a family plan makes it unsuitable for my needs.
So @jottacloud is still my top contender.
