When does an “Every N hours” transfer run?
Short answer: Every N hours (1–24) counted from the previous run, starting with an immediate first run — not fixed clock times. A run still in progress causes the next to be skipped. Use Daily for fixed times.
It runs every N hours (1 to 24) counted from its previous run — the first run happens as soon as you click Start Transfer, and each later run comes N hours after the last one started. It isn't tied to the clock, so a 6-hour schedule started at 10:20 runs around 16:20, 22:20 and so on.
If a run is still going when the next is due, the next is skipped rather than piling up. If you want runs at fixed times of day, use Daily instead.
