Well, tar and cpio are good choices because they are available on the |
| 14 |
Gentoo live CD. If you chose another program, you will just need to |
| 15 |
make sure that you have a static binary of it available at recovery time |
| 16 |
(copying this to your recovery media is the best choice). |

I am currently using 'dar' to backup to external USB hard disk. Dar is |
| 19 |
also useful for backing up to DVD media though, because it has good |
| 20 |
support for creating archive 'slices' that will fit nicely on a DVD, |
| 21 |
just in case you decide to backup /home as well. |
| 22 |

It is in portage, but if you are interested, check out |

For 'quick-and-easy' restoring, I'm not aware of anything that really |
| 27 |
automates the process. But generally the steps are: |
| 28 |
|
| 29 |
1. fdisk |
| 30 |
2. mkfs |
| 31 |
3. mount |
| 32 |
4. restore files |
| 33 |
5. chroot |
| 34 |
6. install boot loader |
| 35 |
7. reboot |
| 36 |
|
| 37 |
The difficulty in restoring the files will really depend upon how you |
| 38 |
make your backups (always full, incrementals, differentials, etc). A |
| 39 |
full backup would always be the easiest, as you only need a single |
| 40 |
piece/set of media and one command to do the restore. |
| 41 |
|
| 42 |
The rest of the steps are pretty much exactly the same as for when you |
| 43 |
installed Gentoo, so there shouldn't be any real surprises there. |
| 44 |
|
| 45 |
One last thing, if you've only got a single CD/DVD drive, you are |
| 46 |
probably going to have an issue to have both the live CD and the backup |
| 47 |
media available, since you can't really eject the live CD to insert your |
| 48 |
backup disk. |
