Hello,

You can easily enable ransomware protection in your existing backup plan so during new uploads your data will be checked for ransomware. But it won't be possible to check the data that has been already backed up. Here is more information about this feature: https://www.cloudberrylab.com/resources/blog/ransomware-protection-with-cloud-backup/

At the moment there is no such functionality, however, we have such feature on our roadmap to specify network interface. Stay tuned!
