Now with B2 we immediately support Linux and provide a client for it out of the box (written in python). Granted, it is only a command line interface so give us a little time to polish it up and add some features.
Another Linux user here who would love to use a command line Python tool to backup my data to Backblaze: with Python I can see how my stuff is encrypted. That's the only reason I'm not using Backblaze right now: closed source client.
My only interest in B2 is backing up for a lower cost than the ridiculousness of S3: at $0.022/GB, I might as well buy a 3TB hard drive myself, put it at a friend's and push my data there. Every month. At the end of the year, I'd have 36TB in hard drive capacity if I bought drives instead of paying for 3TB of S3 storage.
(All numbers are estimates and "roughly"s. Also I don't have external backups now because I'm too lazy to write the software myself, so there is something to say for paying instead of not having it.)
You are ignoring the Electricity/BW costs spent by your friend which would raise your costs
I use backuplizard for personal data/photos which works out more like cost of a one 2 TB disk per year to me and to me Its easy to pay it instead of owning disks and worry about them breaking,etc
I did the math properly once, the S3 costs still didn't work out by far. I have a server here at home and an external hard drive for it, so I know how much power it draws. Bandwidth is free, but in the calculation I did assume I would pay for bandwidth.
All in all, it's by far the cheapest option to store it at a friend's. Storage providers could also cheapen things a whole lot by offering reduced redundancy and whatever else it is they do to make it so expensive (glacier storage is also more expensive than the price I got). It's a backup after all, I don't need my backup to have five copies on spinning (versus offline, non-powered) disks. If my backup dies, I'll upload it again...
