Latest stable in docker. Local back up and remote smb (tailscale) second destination.
I’ve found some older mention of this but nothing recent.
Stop/Abort doesn’t seem to do anything other than change the button text.
I’ve tried a couple of times to stop/abort a secondary destination sync but nothing happens. Have had to restart the container both times.
Same!
I must do this from Time to Time when its Stopped or Abort not working.
Exactly the same problem here, version 2.3.0.1 installed via Docker on an Asustor AS6704T.
Internally, Duplicati will ask the library to stop doing whatever it is doing. However, it is not possible to always stop the process, so in some cases it may take a little while before it responds. In some cases, and maybe the SMB library is especially bad here, the stop signal is simply ignored and the processing can hang indefinitely.
With the latest canary release, we have added the option to run in an isolated process. The spawned process then runs the backup. If you click “abort”, this will then kill the process completely so it does not matter if it handles the stop signal. It is still an experimental feature as we might need to tweak some option transfers between the processes.
You can try it out with the 2.3.0.103 release, and we are always happy to hear feedback:
Release: 2.3.0.103 (Canary) 2026-05-22

An unwanted reply, but keeping with the theme of the original post.
I have used Duplicati for over ten years, I run it on multiple systems (laptops, desktops, servers) and I have never had the “STOP” feature work. Ever.
All I do is kill the process, or log out, or restart the machine, which kills it.
The damn thing just doesn’t work and I don’t recommend that anyone spends any time trying to make it work, there seems to be a low-level issue here and the devs will no doubt get to in once they have stamped out the millions of other bugs holding things up.
I appreciate the reply if nothing else to know it’s not an uncommon occurrence.
I am not really setup to test the canary release but will be interested to see if the isolated process makes a difference.
This problem is still there. Cannot stop/abort.
