While not really a question but more a suggestion. It would be nice if the server time is shown in the Snapshot Pro plugin while you're setting the time for backups to happen.
Might even be good if there could be a dropdown to select time zone so you know you're setting the backup time correctly, e.g. My server is set for UTC (for good practise reasons) but I live in a different time zone which also has daylight savings. I want to know if it's using the WP time zone or the server time.
Anyway my 2 cents.
