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?
