| | |
|---|
| | Précis |
|---|
| | ------ |
|---|
| | |
|---|
| | 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 |
|---|
| |
|---|
| | 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:: |

|---|
| | |
|---|
| | |
|---|
| | Backup |
|---|
| | ------ |
|---|
| | You will also need access to a place to store and retrieve your images. |
|---|
| | In the examples below, we used a NAS nfs share, though you could also |
|---|
| | use another local hard drive, SAN connected storage or even a USB-connected |
|---|
| | drive. |
|---|
| | |
|---|
| | |
|---|
| | Restore |
|---|
| | ------- |
|---|
| | Example Environment |
|---|
| | ------------------- |
|---|
| | |
|---|
| | In our examples below, we're imaging a CentOS 6.5 machine. The only thing |
|---|
| | we need to image is the *operating system itself*. In this example, we know |
|---|
| | there are 2 partitions of interest: |
|---|
| | |
|---|
| | ``sda1`` - The ``/boot`` partition |
|---|
| | ``sda2`` - The rest of the operating system, in this case contained in LVM containers |
|---|
| | |
|---|
| | The idea is that if the machine were to go dead, a disk failed, or what have you, this |
|---|
| | would be sufficient to get the replacement booting properly again. Presumably, you |
|---|
| | could then restore any data files you have from your standard backup/restore tools. |
|---|
| | |
|---|
| | |
|---|
| | Backup Procedure |
|---|
| | ---------------- |
|---|
| | |
|---|
| | :: |
|---|
| | |
|---|
| | mount nas1:/shared /shared # Mount shared storage |
|---|
| | |
|---|
| | |
|---|
| | |
|---|
| | |
|---|
| | |
|---|
| | Restore Procedure |
|---|
| | ----------------- |
|---|
| | |
|---|
| | |
|---|
| | |
|---|
| | |
|---|
| | |
|---|
| | Conclusions & Limitations |
|---|
| | ------------------------- |
|---|
| |
|---|
| | partitions and data partitions. But ... not tested. |
