How do you protect your backups from Ransomware?
Welcome to Acronis forums! I'd recommend taking a look at Acronis True Image 2019 as this product extends the ransomware protection to data on network shares and NAS devices. In addition to that, you'll be able to back up the whole system (not only files or folders) and your mobile devices.
And here some discussions on the topic (how to prevent ransomware attacks/protect your external locations with data)
Should you have any questions, feel free to post!
