Sync macbook air to mac mini
I am finding it incredible that there is no easy way to set up a system so that I can easily sync selected data from my macbook air to my mac mini desktop and vice versa. I've been looking around and there are a dozen cloud based systems that charge a bundle for effectively backing up and then synching data. but that is not what I am interested in. I would like a solution to using my macbook air on the road, then when i get home connect to my mac mini my private network and sync the data that I created, updated, deleted.
I have a time capsule but i am finding it difficult to figure out how to make it work? Is it possible for me to sync my air through the lion server on the mac mini and then backup the server with the time capsule? This seems like it should be a simple and painless inclusion in Lion? It is very un- Apple like that it takes a third party service to simply sync two computers that are in the same location and owned by the same person. I understand that iCloud can do this, but I need more than 200 GB of space and I don't want to pay a fortune. After all, don't they market the air as the on the go computer to go with a mac desktop?
Mac mini, Mac OS X (10.7.3)
