I migrated my backups from Hetzner Object Storage to OVH, because Hetzner had too many service disruptions in the last few months for my taste (no dataloss, only unavailability). My automatic backup afterwards worked without any issues. Plus point, OVH doesn’t charge for traffic or API calls, only for used storage, and has replication jobs, so I can automatically replicate the backups to another bucket in another location.
