| | Many commercial and open source solutions exist to solve the problem |

| | of creating backups that can be restored to "bare metal". 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. You can find the iso image for this disk here:: |
