Well, then I totally misunderstood the problem. I'm not a researcher, so I don't think I can contribute much to your topic.
However, Ransomware these days can:
Lure on you system for a pretty long time until they take action (14 days or longer)
Encrypt USB Disks, as they are attached
Encrypt network drives
Infect other systems connected to your network
Delete existing backups on many online targets (also cloud)
So even if you do a "cloud" backup and have the credentials on your system to do "convenient" backups, it may just delete them.
A way to overcome this is to have an "append only" backup, so that the older backups are secure. I'm not sure you covered this, but as I already stated: I'm not a researcher.
- Xen9 2y agoI believe that most good to the world would be done by first working out the theory & then developing an applet, EG website, that lasts long, and will automatically determine the best possible backup solution "real-world." This would use Bayesian heuristics, openly available data, user's personal requirements. Non-technical granny can press the buttons, it gives them a printable PDF-sheet that says keep three copies of this; these are your best possible backup rules. For a good design, the problem of changing requirements must be addressed. By mapping every scenario imaginable and implementing support for the transitions, usability would increase significantly. This'd answer your problem – I'd call it paranoia – of ransomware. By the way, qubesos can make at arbitrary times exact or near exact VM image backups, and and move files from one host OS to another, without shutting down, mitigating every non-targeted piece of ransom malware & majority of non-state-backed targeted ransom malware.
