It doesn't actually give me a breakdown because I still have $170ish in credit from my $300 free trial credits for signing up. The esitmator says $4.50/month though. You do have to change the type over to archival, and if you have many small files and don't do it in one big upload (i.e. many restarts), then you pay easily $60-100 in API calls (for each file, checking date/size comparison for cloudberry to compare if needs to be re-uploaded or not). But once you get it uploaded, it looks like it should be under $5/month moving forward. And with that $300 free credit, you basically get 4 years worth of backup, though I think the credits might expire after 1 year, so just 1 year free maybe? I'll let you know next year
