my method to backup/clone a system for transfering to another system of the same -march is simple..
| Code: | | tar cvjp --exclude=/dev --exclude=/proc --exclude=/sys --exclude=/stage4.tar.bz2 --file stage4.tar.bz2 / |
then simply scp that tarball to your new system,.. untar it, then simply cd into the /mnt/gentoo/dev directory and run [this will create the necessary nodes. after mount proc & dev then finally chroot to it. that's it; you should know the rest. |
I tried this and have trouble after chroot when I boot into the new system. udev complains
| Code: | | Letting udev process events !! |
and then e2fsck complains it can't find /dev/hda3 and it throws me into root for a manual fsck. When I look into /dev, I can't find hda3. All that's there is | Code: | | console core fd null pts shm stderr stdin stdout tty1 |
.
Any pointers will be welcomed. |

did you recompile your base system?
make sure to compile the kernel and check if you have the require IDE/SATA drivers. |

I compiled the kernel and rebooted and got the same result. dmesg shows that the hard disk, hda, was detected and prints out the correct partition. But /dev still has only generic nodes and, in particular, hda isn't in there. When I try to mount /boot in the root shell that e2fsck throws me into, mount correctly complains that there is no /dev/hda1.
When do these device nodes get created? Would it work if my source backup included /dev?
Thanks.
[EDIT] Re-emerged udev and all is well. Thanks. [/EDIT] |

By the way, I saw a little bug inside my current box.
If you have a /boot, before starting your tar command, double check inside /mnt/back/boot if you have something.
If not, run this command :
| Code: |
# mount -o bind /boot /mnt/backup/boot
|
The bind command is only working for a specific partition at once.
So, I had a / for sda8 and a /boot for sda7. |

| Posted: Thu Oct 30, 2008 7:51 am Post subject: bare metal recovery trick |
|
|
Here is how I keep my bare metal backup of my laptop when i transferred my data to a new drive:
WARNING!! WARNING!! WARNING!! This command if mistyped can HOSE the host system! Always triple check the command before pressing enter!
this does require a lot of space on the host system.
I moved my laptop sata drive to my desktop and ran
| Code: | | dd if=/dev/sda of=/home/jawall/laptop.bare.img bs=512 |
after the data was copied I disconnected the old drive and hooked up my new drive and ran
| Code: | | dd if=/home/jawall/laptop.bare.img of=/dev/sda bs=512 |
This command will take several hours to run so don't get impatient over no status updates it IS working.
To explain the command: dd is a command that does binary copying quite well
is the source file whether it is a device node or image file
is the output file
tells dd to copy the hard drive sector by sector
for more ways to use dd run

This backup the whole HDD and this will recreate the same partition from your old installation.
But if you want to be a little bit more flexible, then the Stage 5 can recover any backup partition from any size.
In fact, I had to backup a 10 Gig of data from /, and then I untar it on a brand new 100 Gig / without any warning or else.
DD is awesome to take an exact copy of a partition or a HDD. |

d2_racing,
I'm a little unclear on your statement here. How is it that Stage 4 crashed your Gentoo? Are you implying that running the script destroyed your functional Gentoo system? I've never had any problems with running the script myself.  |

No, I mean if you restore that Stage, if you have a Framebuffer and other stuff like Gensplash, the Stage 4 doesn't backup at all the /dev directory and other stuff.
With the Stage 5, you don't have this kind of problem. |

thanks it was usefull 
Just two questions
| Code: | | # tar --exclude stage5.tar.bz2 -cvvjpf stage5.tar.bz2 . |
Why is "." so important and why 2 "v" in the tar command.
In your pdf on your website for the stage 5, there are 2 mistakes.
| Quote: | | L'option bind est fonctionne seulement pour une partition a la fois. |
and the command is missing a "-"
| Quote: | | # tar -exclude stage5.tar.bz2 -cvvjpf stage5.tar.bz2 . |
btw when i copy and paste the command i get
| Quote: | | # tar {exclude stage5.tar.bz2 -cvvjpf stage5.tar.bz2 . |
not the minus signs.

|
The . is important, because it will tar the current directory, so basically the /mnbt/backup
And the extra v makes the tar command more verbose. |

Can you add this line to the main guide please

Imho backup should be from remounted rootfs
| Quote: | mkdir /tmp/real_rootfs
mount /dev/root /tmp/real_rootfs |
remounted rootfs have not mounted nothing, empty /proc and /sys. /dev with static files, nothing mounted in /mnt or /media.
| Quote: | mizore /tmp # mkdir real_rootfs
mizore /tmp # mount /dev/root real_rootfs
mizore /tmp # ls -l /tmp/real_rootfs/dev | wc -l
1467
mizore /tmp # ls -l /dev | wc -l

| I have a problem extracting backup. A few days ago I didn't have any problems, but today I just can't extract bz2 file, some files extract but after some time I get error, something about reiserfs_priv (it is reiserfs partition). Could be the reason that I am using different boot CD that I used a few days ago when extracting went smoothly? |

Hi, did you try the latest SystemRescueCD ?
I always use this one when I backup or restore my box. |

Hi, I am using Gentoo minimal cd to boot, filesystem is made with mkreiserfs. The problem is that a few days ago there were no problems with extraction on the same computer. This is error:
| Code: | tar: ./.reiserfs_priv: Cannot mkdir: Permission denied
tar: Error exit delayed from prevoius errors
|
Edit: it is the same with SystemRescueCD. As I understand reiserfs_priv is hidden folder with filesystem files, which can't be modified. What I can't understand is why I didn't have any problems the first time with the same bz2 file on the same partition . |

Thank you d2_racing your guide worked great for me to re-do my raid array from raid1 to raid0 ... I somehow managed to miss my /boot directory (must have forgot to bind it) but installing grub/memtest86 and re-compiling a kernel was super easy. Too me 300min to tar/bzip2 45Gb and 100min to restore. Much better than a full re-install... Thanks again.

In fact, it's universal, I used this method to backup my FreeBSD 7.2 and everything is working #1.
It's the swiss knife for backup |
