Does upload to Backblaze B2 storage cause automatic download?

Thanks for the pointer. I looked in the forum and found the following that is the closest to the problem I have.

High traffic to primary storage (S3) from nextcloud

Hello everyone, I am using nextcloud with a s3-like storage (wasabi) as primary storage and I am wondering about the high download-traffic as there are only a few uploads a day. The bucket is only used by nextcloud (and via nextcloud). Between the storage and nextcloud is minio running on the same server like nextcloud for encryption. Here are the stats for a period of 16days after initial synchronization: Download-Traffic from s3 per Day: 160-175gb Upload-Traffic to s3 per Day: <0.5gb Stor…

No solution there as well. Is there a log file where I could check the S3 API calls being made or the file operations?
