Where do Synology apps like Calendar store their data?

I have been slowly adding synology apps to my DS1019+ since putting it together back in March. I have been playing around with the idea of using the calendar that you have a review on your site. I don't use Hyperback but instead use a cloud service called IDrive backup which is inexpensive and has no issues backing up the data in named volume directories. I don't see anywhere in Synolgoy's documentation on how to protect calendars or shared calendars with backup. Can you point me in the right direction?

Well it took a while poking around the internet and the answer is that all the data in Calendar is stored in a database and managed by the Calendar application service. If you use Hyperbackup and configure and tick the box in task settings/applications it will stop the service, backup the database and restart the service. Not much option for user alternative cloud services like iDrive natively.
