Like I said I haven’t found my ideal solution yet. I’m using multiple offline harddrives at my home and at my parents home. So my backup is more or less save from most problems/attacks. But its not really up to date and its a lot of manual work always pluging them in when I want to make a backup und copying the files.

I wouldn’t necessarily trust a cloud so I would encrypt my files before uploading and wouldn’t use the cloud as my only solution. Because they guarantee for nothing and could just delete your account or their service. But it can expand your backup with another layer.

(Haven’t found my perfect solution, just some thoughts)
