Weekly Cloud Backup - what day of the week?

I noticed that the hubs that I put under the Protection Service have automagically scheduled the Cloud Backup at the same time of day as the local backup but on an interval of Weekly. What day of the week is the Weekly Cloud Backup done? Is it a week from whenever I initiated the service? I doubt I will remember that. Is there a way to see what day of the week it is scheduled?

I also noticed the Cloud Backup was scheduled on two of the hubs (a C-4 and a C-7) but not on one of the hubs (another C-7). I rebooted that hub and then the Cloud Backup job showed up as scheduled.

@bobbyD Can you tell me who can answer this question?
