how do you create repeating backup policy?

NBU 7.6.0.3

i created a backup policy that should repeat every hour.

so what i did is schedule the new policy to start today at 1pm up to 3pm. since i chose the schedule type to be "Frequency 1 hour", i was expecting it to execute again.

questions are:

1. since the backup took only 10 minutes, i thought it would execute again 60 minutes later, ie at 2:10pm (this didn't happen)
2. since the backup window is from 1pm to 3pm, i thought the policy would execute again an hour after 3pm (so this one i'm still waiting)

are any of my above assumptions correct?

appreciate any help.
