That is, +restoring a system *image* back to a disk when the machine will no +longer boot or a disk has to be replaced. Image backups are preferred +when rebuilding systems so you don't have to manually reinstall every +application, system setting and so forth. + +The purpose here was to do just that - create images capable of being +"poured" onto, say, a blank, new hard drive, but *using only standard +linux commands and tools*. + + +General Approach +----------------- + +The idea is to make an image snapshot right after you build a machine, +and anytime thereafter you make significant changes to its operating +system and application configuration. You might do this, say, right +before patching a server so that, if patching breaks the server +to the point where it will no longer boot, you can just "pour" the +previous image onto the disk. + +To do this, we reboot our target machine using the *Linux System Rescue CD*. +This CD has all the tools on it we need to do both image creation and +restoration.
