Re: in a way, but
Your process is admirable, but not in the realm of technical capability of Aunt Kath. Remember the comment thread you are replying to basically says that about 3% of disks will fail without any malicious ransomware, so it is hard to have sympathy for those without backups. That's why I think of who the victims are. The average El Reg commentard is too super DevOps skilled to fall for the phishing schemes that deploy this ransomware. But our Aunt Kath will go right ahead. So the people most at risk of infection would have no clue what rsync or hard links mean and the concept of incremental backups isn't even on their radar.
