This is meant to be a sample article to show you how to create schedules for scenarios where you have the first or last day of a month for running full backups or in a GFS type scenario, etc.
Go to Manage -> Schedules and then click on Create Schedule.
Give the Schedule a Name and a Description.
Then Choose the day of the week (in this case Friday).
Click the box next to the right of the Months (this will add all the months in for you).
Then select the first 7 days of the month since.
This tells the schedule you only want Fridays that fall within the first 7 days of the month. You can use this same logic for end of month backups etc.
