The numbers you are shared are mind-blowing to me. Can you confirm: Do you pay your bill (1) monthly and (2) by automated credit card payment? If yes, don't the credit card transaction fees paid by Backblaze exceed the amount!? This post has literally inspired me to sign-up. I have put off Internet backups for a long time!

It seems around 0.6€ is where they judge it worthwhile to create an invoice. I have even less data (because I only backup my server there, for my PC I use backblaze personal with payments every 2 years), and they charge me 0.6-0.85€ every 2 months.
