Dear CentOs users, I have a centos server with nothing important at the moment, but I would like to install some web-based project management tool (trac for the curious) that would contain important data. And, as my network is growing the configuration of the server is becoming complex. I would like to have a proper backup so that I can restore the whole system easily, should any problem occur. What do you recommend? I'm not an expert on this, so my first idea is that I could do a per application backup and create a tar file of the /etc. The latter especially could be too naive. And, a push-the-button method that handles all in once, not depending on the app number would be much better. Another thing: how I could do this to be safe across a centos upgrade? - Gergely
