S3 bucket usage increased dramatically

Hi All,
I deleted the backup from my S3 bucket so that Mailinabox could start backing up again, but now I’m facing the issue of data transfer costs. Uploading files to AWS is free, and I wasn’t previously paying for data transfer out (download from S3).

Now my question is: Does Mailinabox download from the S3 bucket?

  • The bucket access is not public.

Thanks in advance for your help. (Screenshots attached)

The backup location currently contains the backups listed below. The total size of the backups is currently 105 GB.
