I had backblaze, and it’s really a bummer they don’t support linux. The closest one I’ve found is Icedrive, but it costs a bit more. I don’t mind paying a bit more though for a FOSS solution (technially not free but yeah). I probably only have 2 TB of actual important stuff but it would be nice to have more for future.
I use Woelkli’s Nextcloud server. It’s free.
me, too, but it only allows 2GB. If you plan to encrypt it for when you aren’t needing it, then you can only use half that as encryption doubles files. I’ve been wondering if Owncloud, NC’s close cousin, has a free account, too. I could use Owncloud for images, I guess.
