I need this as template

At the moment I use https://github.com/JonathanTreffler/backblaze-personal-wine-container

Something like this https://emailengine.app/ ?

I had a dedicated place for comics. I weekly rotated the content and always had entertainment. Maybe I should start doing this again.

But moving to the HDDs and back is pretty slow, because the cache drive contains many many small files. This is why I asked if it is possible to do it this way. Because then it would only be a ssd => ssd transfer.
