Go to Applications from the left side menu and then to Backup SLAs
Provide a policy name
Select your application from the list
Specify backup rule details - especially backup destination and schedules
The second part is a schedule for policy:
Change tab from Policies to Schedules
Create a new schedule for application policy - create it just like other schedules, enter name, choose execution time (time or interval) and days of the week. *optionally you can select policy if already exists
Now your application backups will be done periodically according to your policy.
