I've a Ubuntu dedicated server at 1&1. I'm new to Linux. I do read a lot of HowTo, and sometime when something is not going properly, i read forums and people get these kind of answers: "Did you backuped your data? There's no uninstall procedure for this software. You will have to Re-Image and start from scratch"...
I would like to know if it's possible to do an image of the server while it's running, on a 2nd partition, so if anything goes seriously bad, i can reload that image and be up & running in a couple of minutes? (Keep in mind that i also don't have any access localy to 1&1 datacenter)
One thing i don't understand also about "Re-Image" is, what do they actually re-image? The whole disk? Or just the OS partition?
thanks for your help
