I'm currently running firmware version 4.3.3.0299 Build 20170901 on a TS-253A and Hybrid Backup Sync v2.1.170818 and the B2 storage is nowhere to be found.QNAP Hybrid Backup Sync consolidates backup, restoration and synchronization functions into a single QTS application to easily transfer your data to local, remote and cloud storage. Using QTS 4.3.3 and HBS v2.1.170615 you can now sync the data on your QNAP NAS to/from Backblaze B2.
Any ideia where is the B2 option?
