If I have a home server connected to Proton Drive for example, would that be sufficient to back up my data?
And I would argue that all data should be encrypted now, even the working copy. If you have data that’s worth backing up, you probably don’t want it in the hands of criminals or weirdos either.
It’s so easy to set up, just tick a box during os install most times. Then if you do rcline just use an encrypt on top of your remote, make sure your conf is backed up, and you’re golden
If you tick the encryption box during install, you will have to enter the decrypt password at every boot and that means that if the power goes out for long enough (UPS doesn’t keep the server up for hours), I (and my family) will not have access to the self hosted stuff until I’ll be home and this is why I encrypt only the data partition and not the boot one.
You can decrypt via ssh at boot. I used dropbear to accomplish that on my machine
