I got such a quick helpful response to my last question, I'll try again. I'm quite new to linux, but very keen to learn. I routinely run "Live Update" to get updates from Acer, but I'm wondering about the "Software updater". Is it safe to run this? Are there any special considerations before I do run it? Someone will probably tell me to backup my computer, so what backup program is recommended for a novice linux user. Thanks again, Basil
