I've never done this before so it seems like right now would be a |
2 |
great time to learn. Thanks in advance. |

I've just done this installation on my laptop. For the most part it's |
5 |
working fine. Still a few things to iron out but it's good enough that |
6 |
I'd like to save the state of the machine so that should something |
7 |
happen I have a way to restore where I am today. Since the disk usage |
8 |
is currently about 4GB it seems like a great time to do it. Is this |
9 |
possible? I think it's essentially what the stage 3 file is that I use |
10 |
when I install, isn't it? If I can keep the whole thing under 5GB then |
11 |
I can write it on a DVD and I'm in a really safe space for a fast |
12 |
reinstall if something happens. |
13 |
|
14 |
From the running system here's what things look like right now: |
15 |
|

laptop1 ~ # df |
17 |
Filesystem 1K-blocks Used Available Use% Mounted on |
18 |
/dev/sda5 15820524 3641240 11375636 25% / |
19 |
udev 10240 172 10068 2% /dev |

/dev/sda6 1320272 189304 1063900 16% /var |
21 |

22 |
shm 1003844 0 1003844 0% /dev/shm |
23 |
laptop1 ~ # |
24 |
|
25 |
My thought is to boot using the install CD, mount a USB drive at |
26 |
/mnt/gentoo, then create a mount point 'backup' on the USB drive to |
27 |
mount each of the 3 partitions I want to back up one at a time. ( /, |
28 |
/var and /home) Then I'll mount each partition by itself and use tar |
29 |
to create a single file for each partition where that file gets |
30 |
written on the USB drive. When I'm done I have 3 files. |
31 |
|
32 |
Restore would be to create the partitions anew, untar, install grub |
33 |
from in the chroot, and reboot. |
34 |
|
35 |
Is this a reasonable way to go? Is there something easier? (That seems |
36 |
pretty easy to me...) |
37 |
|
38 |
I don't want to create images of the partitions because I might want |
39 |
to put the data onto a different drive or in a different |
40 |
configuration. (Like no /var or something.) |
41 |
|
42 |
If this makes sense then what commands would I want to use to do this |
43 |
correctly. Presumably it needs to tar up links, file system |
44 |
permissions, and everything else. Since the Quick Install guide uses |
45 |
|
46 |
tar xjpf stage3* |
47 |
|
48 |
to extract the main directories & files, and assuming the USB drive is |
49 |
sdb1, would I just use |
50 |
|
51 |
mount /dev/sdb1 /mnt/gentoo |
52 |
mount /dev/sda5 /mnt/gentoo/backup |
53 |
tar cjfp ./ROOT.tar.bz2 backup |
54 |
|
55 |
and then repeat for the other two partitions? Or is there more to it? |
56 |
|
57 |
I'm rambling here so I'll hope for a quick answer and then give it a try. |
58 |

Thanks in advance, |
