I would like to be able to set up Kopia to retain, for example, all hourly snapshots for the last 2 days. It might seem that setting it to retain 48 hourly snapshots would achieve this; but with “Ignore Identical Snapshots” turned on, it is possible, and in many cases likely, that this will result in many more than 2 days worth of snapshots. Therefore, I would like an option to discard hourly, daily, weekly etc. snapshots after a given time period, rather than a given number of snapshots.
