Hugo Queiroz shows off something new in SQL Server 2022:
Backup and restore to simple storage service (S3)–compatible object storage is a new feature introduced in SQL Server 2022 that grants the user the capability to back up or restore their databases using S3-compatible object storage, whether that be on-premises, or in the cloud.
There are some differences from other backup operations, so you should definitely read up on it before using it. One interesting side benefit I got to try out recently is that Pure Storage’s FlashBlade product has an S3 API, allowing you to use that interface for backup/restore operations as well as data virtualization.
