As others have pointed out, just get a VPN and run your torrents through that. I’ve used AirVPN and ProtonVPN. Both are P2P friendly and even offer inbound port forwarding. It would be easier to setup and likely cheaper too. Proton is incorporated in Switzerland and has servers all over the world.
For my use, it actually cost less to use B2 than the home backup product. The bulk of my data is Linux isos so I’m not really worried about losing it.
I do use ZFS and I just backup the files with restic. To restore a file in a zfs snapshot I would have to download the entire thing to a spare HDD, even if I only need to recover a few files. Restic has snapshots too and is designed to be used with cloud providers like B2.
I’ve used backblaze b2 for almost 8 years now and it just works. I’ve never had any data lost by them in that time.
I just recently switched over to Storj.io as it a bit cheaper at only $4/TB as compared to B2 at $6/TB. Both are S3 compatible and work with just about every backup software out there. I have used Borg, Kopia and now Restic to do backups of important data. All 3 tools deduplicate all your data and reduces the amount of storage used. They also do encryption client side and are open source. They also have a built-in verification mechanism that checks the data is intact.
Works great. Setup a month ago and imported over 600 documents, both digital and scanned. Makes backup a lot easier too as everything is in one place now.
It was AT&T
I went that route with an unlocked ASUS zenfone and it turns out that phone is impossible to replace the screen on because replacement parts are not available where I live. I had to buy a new phone without a headphone jack. Check for parts availability before buying something from a smaller brand.
GrayJay just came out into the testing phase. It not only supportsYouTubee but also Nebula, Odysee, Twitch, PeerTube and a few others with more to come. Works great so far. grayjay.app. Built by Futo, a nonprofit company which Louis Rossmann works for. His video here
I use restic with a wrapper script to automate it on all of my machines. The backend storage can be anything that speaks S3, so B2, or iDrive would both work. I currently use Storj for my backend. It’s globally distributed storage, so no single point of failure geographically and it’s cheap. Backblaze is also a great company, but I’ve grown a little skeptical since they went public.
