How to do backup

[cljoly]

I couldn't find anywhere how to access to data stored in the calendar.

I would like to copy a file (on a computer, USB key, ...) with my events to back them up.
I prefer do not to use online services.

Is there a solution to do backup this way?

You can use another app called "Calendar Import-Export" for this. Another option would be to use cal caldav server.
