Back up like an expert with rsync. What's so great about rsync?
First, it's designed to speed up file transfer by copying the differences between two files rather than copying an entire file every time. For example, when I'm writing this article, I can make a copy via rsync now and then another copy later. The second (and third, fourth, fifth, etc.) time I copy the file, rsync copies the differences only. That takes far less time, which is especially important when you're doing something like copying a whole directory offsite for daily backup. The first time may take a long time, but the next will only take a few minutes (assuming you don't change that much in the directory on a daily basis). Another benefit is that rsync can preserve permissions and ownership information, copy symbolic links, and generally is designed to intelligently handle your files. Rssh - FAQ. Contents.

If you’re anything like me, you always want the latest, shiniest stuff running on your machines, even if you’re not supposed to be able to do so. I think that this is what FC12 was trying to tell me by flashing a very brief message along the lines of “You do not have enough RAM to run the graphical installer.” whilst trying to do a clean install on an old P3 800Mhz machine (a quick search confirms that I’m not the first to get this). It subsequently kicks into text mode installer, gets your keyboard, partitioning, root password and timezone settings, then goes off and installs exactly 200 packages without even asking you what you want to install. When it is done doing that, it reboots into runlevel 3 (console) and you get no GUI as you would expect.
Obviously with only 200 packages installed, I doubted that any GUI would have been installed anyway and sure enough, startx confirmed that. yum to the rescue?
