Copy-on-Write filesystems have the nice property that it is possible to "clone" files instantly, by having the new file refer to the old blocks, and copying (possibly) changed blocks.

We will see how to use it on the XFS filesystem.

In this article we will discuss about how to access a RaspberryPi desktop remotely with VNC. We will use a VPS with Docker Scripts and sshtunnels as an intermediary between the server and the client, in order to enable a secure communication between them.
