Azure Backup Agent for QNAP
This backup agent should only transfer over the wire the changed bits of a modified file.
We are looking into the requirements. Can you please elaborate the scenarios?
Paul Chu commented
QNAP offers an agent to back up data to Azure Storage.
Does this work for you?
Silvio Di Benedetto commented
Right! QNAP is a storage for SMB but also for Enterprise with many agents. With firmware 4.1 is possible use SMB 3.0, so a perfect repository for VM.
In this scenario a company could use the storage to save files to Azure without intermediate.
