When setting up an intervall of 86400s, then KopiaUI will start a snapshot every day at 00:00 UTC. If it happens, that my MBP is alseep at this time, KopiaUI will start the snapshot as soon as my MBP wakes up.

When I schedule snapshots to be run at 20:00 and my MBP happens to be sleeping and missing the next snapshot, KopiaUI will not start a snapshot after it has woken up again. Is that deliberate?

We could add backup window to policies as suggested elsewhere. I’m fully swamped with other things right now but would be happy to review PRs that do it.

Also to answer your question: it’s not deliberate looks like a bug.
