Welcome to the forum @RaptorG
Thanks for continuing this discussion. Unfortunately, many of the previous posters participate less now.
If you read through this (and also [feature request] Changing volume encryption password #2991), much discussion involves where to save the encrypted keyfile, however like so many other features, somebody interested in implementing it needs to volunteer. Thank you for your recent forum help. Do you code too?
As a small side note, Duplicati’s commandline tools don’t use the Duplicati-server.sqlite database, however there are other ways to achieve redundancy, Which to use might depend a bit on what’s simpler and covers all the needed cases, including all the command line tools, and also the Python restore script .
