When I researched what to use for my backup I found rsync.net. They have some nice features nobody else seems to support, like they support ZFS send/receive https://www.rsync.net/products/zfsintro.html
But in the end the price made me go with borgbase.com
I bought my edge grain cutting board there. They have 2" versions as well as up to 6" versions (https://www.holz-liebling.de/produkt-kategorie/schneidebretter/hackblock/) You could look at their pictures to get some hints at what you could do.
