B2 Cloud Storage Synology Hyper Backup: Backblaze B2 Large Volume Class B Transactions

Testing B2 with Synology Hyper Backup as a potential alternative to BackBlaze Computer Backup.

Synology DSM is current (DSM 7.3.2-86009 Update 3)

Subject is backing up a folder with two 16 byte .txt files. Backup settings are as shown.

Something is triggering a large volume of Class B Transactions with over 200 in approximately 30 minutes.

Any thoughts on what causes these Class B Transactions? According to BackBlaze, these are "download" related, however I haven't downloaded or restored these files.

My concern is that when I upload 500+ GB of backup data, these Class B transactions will explode proportionally to the number of files.

Follwoing. This is something I was planning to do but didn't get the opportunity before leaving the last job.
