Thanks for pointing that out. Existing backup jobs need to be modified to use the new path to the local DB’s.
If Duplicati could somehow test if the Duplicati Server instance is started with the SYSTEM account, it could change the storage location from %APPDATA%/%LOCALAPPDATA% to %PROGRAMDATA%.
Not sure if there could be any security issues, %PROGRAMDATA% contents are accessible for all users, the systemprofile isn’t. Hopefully there are no big issues with that, because
--portable-mode has the same effect.
Note that using %PROGRAMDATA% is also discussed in GitHib issue 2222 and 2826, maybe these can be combined in a single fix.
