Starting to use duplicati again after years of absence (had been using crashplan instead), I thought to think this true indepth.
The one threat I still see is that a particularly nasty Trojan will steal my cloud logins and delete the blocks there. Only real solution I could think of so far is to backup using sftp to a machine that will prevent deletion by changing permissions accordingly (or using a copy on write type FS). But obviously that brings the headache (and expense) of having to maintain such a machine vs simply using Cloud storage…
Is anyone aware of a solution to address this? (I was thinking of reaching out to backblaze to ask if such a limited permission account could be introduced to b2).
Thanks a lot.
