At SnapShooter we are no stranger to data. Our customers love using B2 for storing their backups, we love storing our backups there too.
The API works perfectly conforming highly with the AWS S3 API. Making integration a breeze.
If you measure for just data B2 comes out clearly on the top with SnapShooter customers for backup storage, things like MySQL Backups, File backups and database backups.
My only comment that is negative is sometimes uploading can be a little slow.
