Thanks for hovering over the processes to show the full path of the programs. That’s exactly right for a situation where you have a base version (can’t tell what it is – you can look at changelog.txt if you want the version) then 2.0.4.28 update applied by the Duplicati autoupdater. The base version in C:\Program Files\Duplicati 2 will look for an update, validate it by reading all of its files – this is the read-heavy part, then run updated code. Child WindowsService process then starts Server unless Windows times it out (default of 30 seconds) first, and the Server that runs is the same version as the child WindowsService.
[SOLVED] Is it ok that I see 5 processes of Duplicati in Windows Task manager? explains the process.
A service does not start, and events 7000 and 7011 are logged in the Windows event log gives events.
How to increase Windows service startup timeout period gives them too and says how to raise timeout.
If you were on beta, it’d be easier to just do a .msi install every now and then, but if you stay on canary then the automatic update might make it worth adjusting the startup parameters until it starts and stays.
