I’m using Duplicati to back up a Windows PC. Duplicati is set up as a service, SYSTEM account, with no tray icon.
The PC typically goes to sleep after idle in the evening. I have the PC set to wake via a scheduled task at 01:56. That seems to be working: I can see the resume in the Windows event log. Then I have my Duplicati backups scheduled for 02:00. However, they don’t seem to start.
When I log on in the morning, and go to the Duplicati UI I can see the backup has just started. The time it shows that it started is immediately after the wake that I generated by wiggling the mouse. There’s no record in the UI or logs of anything happening at 02:00.
So it seems like when the computer wakes with the wake timer, the Duplicati scheduler doesn’t start. When I wake the computer with the mouse much later, the scheduler does start and immediately starts the missed backup.
I’m a bit of a newbie so maybe I have something set up wrong in Duplicati. Or maybe this is an issue? Anyway, any suggestions for diagnostics that might help?
I notice some earlier posts with similar but not identical issues: they suggest I restart the Duplicati Service on wake, as a workaround. I could do that but it seems it might be worth looking into the problem more first.
Windows 10 2004, Duplicati 220.127.116.11_beta_2020-01-18
