I’d recommend setting your sights on the 3-2-1 rule. 3 copies of your data, 2 different mediums, 1 off-site. Hetzner Storage Box is a good cheap offsite option.
I don’t backup everything to a 3-2-1. I at least have everything on a 2-1 backup scheme. Two copies, one offline. My personal photos and videos are on a proper 3-2-1. I can redownload my movies and music. I can’t retake pictures from my childhood. It saves a lot of money doing it that way. My personal media is less than 1 TB, whereas my whole collection is many TB and would be prohibitively expensive to 3-2-1.
