Backup&Export all Contacts and Calendar (automated)

I opened a different discussion concerning the disk failure scenario - shouldn’t be too hard to do scheduled backups to a different disk without having to run two Syncloud instances?
My idea is to use FreeFileSync on a User’s PC to backup all the important files regularly. This way one wouldn’t have to physically access the Syncloud device for every backup.
I’d be happy to write something for the wiki once we figured out an easy way.
