Need backup for "My Calendar" on S3 I have tons of info on "My Calendar" Galaxy S3, and Google Calendar sync is one-way only. I actually use a Yahoo email and would prefer to sync both ways to Yahoo or Google, but since I cannot find a solution to this, I just need a backup that I can run periodically. Please help!
You can use Samsung's Kies program.

The link below describes some details of the program.  It includes backup of calendar as well as most other content of your device.
