This is an old revision of the document!
When I started building my personal cloud, I wanted several things:
Manage all my data by myself. I love Google tools, but I really want to have the full control of my data.
Be able to have a backup of my data in two different sites in case of disaster
Have a “cache” of my data at home in order to be able to access it even when my internet bandwith was low.
This is the architecture I set up:
I made a quick test that shows the powerfullness of this cloud:
Take a picture on my smartphone
Wait automatic upload to the owncloud server
Wait download to the NAS through raspberry pi
The picture was available on my NAS at home only 1 minute after it has been taken without any manual action.
