I literally just started my free trial of Wasabi to see if it can replace ACD on my Windows. we're not their target, AWS S3 and maybe Glacier users are, with their pricing a hair below Glacier's, no API charges, and egress bandwidth undercutting AWS but not B2. before their recent and easy fundraising round, they only had runway to the end of this year. If we assume their technical durability is about the same as Backblaze's (while Backblaze has two data centers now, your data is going to be on one or the other), I don't see any reason people like us doing sane backups that won't use excessive APIs would use them over B2, their 'business durability' is unknown but on general principles has to for now be viewed as much less than Backblaze. And I think I saw something about their maybe later charging more for multi-region class of storage. We don't know if they duplicate your data between the two sites, all they say is 'we use best practices', but given their pricing, I'd doubt it. In the Hacker News topic one of their people said they have two, one in their home state of Massachusetts, one in Northern Virginia.
