Backblaze B2
A quarter of S3's storage price, with free egress to partner networks.
42
sovereigntyB2 is about $0.006 per GB per month — roughly a quarter of S3 Standard — with free egress to Cloudflare and other Bandwidth Alliance partners and generous free egress otherwise. It is S3-API compatible and the company has published its storage-durability statistics for years, which is a level of transparency the hyperscalers do not match. For backups and archives specifically it is very hard to beat on price. It is proprietary and hosted, and the ecosystem around it is small compared with AWS.
