But, this is a basic overview of how to prevent NAS ransomware attacks: https://www.howtogeek.com/435452/how-to-secure-your-synology...
There is better advice elsewhere but this is a good start.

Acronis is Swiss-based and has to comply with the GDPR, due to its direct ties with the European Union. I am a dual US|EU (Croatian) citizen, with legal rights to work/live/retire in Switzerland, so I do not have to worry about storing my information "abroad".
The EU has strict regulations, and they are only going to get stricter. There have even been talks about the EU being allowed to legally break encryption recently. If you are a third-country national (not an EU/EEA/Swiss citizen), then I do not recommend Acronis cloud backup or any other EU/EEA/Swiss service for storing your personal data. America may have its problems, and privacy may be a joke, but at least you have rights and sovereignty there.
It's actually managed by a side project of mine: https://github.com/nicbou/timeline
Itβs called having a network attached storage (NAS) device. I have a Synology NAS, which I backup to, continuously at 5 minute intervals.
Warning: Microsoft image and file backups sometimes do not work.
I recommend Acronis True Image instead, which comes with antivirus. It pretty much always works, never falter never fail. Get the version that allows you to back up to the cloud with blockchain features. You will be happy you did.
