Yes you did. Apologies.

If you pick it up, you can consider (probably after code study) whether or not going “full cron” is best, e.g.

> If time has moved forward, those jobs that would have run in the interval that has been skipped will be run immediately.

sounds to me (and you can confirm – you have more cron skill) that you get a burst of jobs in the Spring.

```plaintext
1:45 job every 30 minutes
1:45 AM
2:15 AM doesn't happen
3:00 AM roughly 15 minutes from previous
3:15 AM roughly 15 minutes from previous
3:45 AM

```

I’m proposing that the chosen interval be maintained, basically just pick the right UTC for the next time.

```plaintext
1:30 job every 30 minutes
1:30 AM
3:00 AM
3:30 AM

```

Duplicati does have a missed-job practice of ASAP run when Duplicati starts. Maybe it could be used,  
but I kind of think staying on requested interval is better. I don’t administer systems. Feedback sought.

Of course almost anything other than the current plan is an improvement, so where it lands may vary.

[Scheduling strategy for backups](https://forum.duplicati.com/t/scheduling-strategy-for-backups/1309/8) has design information from the original author to credit for Duplicati.  
Everybody wishes it were better than it is (ever getting out of Beta?), but the resources are super thin.

I didn’t start the project, I don’t run it (but I do have a little bit of say), and I wouldn’t be writing the code.
