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 a 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.
There is no limit to the number of policies you can create.
