Hi!

I need to send in my laptop due to a crooked case...

I therefore have to make a 1:1 copy of my Harddisk including partitions and everything and put it back on the disk afterwards.

What is the best way to do this?

Thanks!!!

Hallo!

For my system backup, I use the following commands:

Code:
cd /
rsync -RavH /bin /boot /etc /home /lib /opt /root /sbin /service /usr /var [host:]/<path to>/<image destination directory>
cd /<working directory> [<-- (A directory that has some free space to be used by tar verification process)]
tar -cpvW -f /<tar destination directory>/<File Name> -C /<path to>/<image destination directory>

(If necessary)
cd <tar destination directory>
bzip2 -kzp <tar file>


You can include on the above rsync command any directory you want. /service is a directory used by my MTA which is qmail.

Rsync always verifies the data synced. If you specify a host, the connection will be established through ssh.

To restore your system, you have to do the following:

Code:
1. Boot from live CD, create, format and mount your partitions according to the handbook and your previous settings.
2. Install stage 3 from Gentoo startup disk: tar -xvjpf /<path>/<stage 3 file>
3. Remove the directories included in the tar(.bz2) backup file:
   rm -R -f /mnt/gentoo/bin/* /mnt/gentoo/boot/* /mnt/gentoo/etc/* /mnt/gentoo/home/* /mnt/gentoo/lib/* /mnt/gentoo/opt/* /mnt/gentoo/root/* /mnt/gentoo/sbin/* /mnt/gentoo/service/* /mnt/gentoo/usr/* /mnt/gentoo/var/*
4. Install your backup file : tar -xv(j)pf /<path>/<file> (option j is used only if the file is tar.bz2)
5. Chroot and execute grub-install
6. Exit chroot, reboot and you are ready!


The same procedure a bit simplified goes for my data directories.

Kind regards,
orange_juice

I would use partimage... booting the laptop with the Gentoo Livecd 2006.1
In addition to partimage, dd should be used to backup the MBR, and sfdisk for the extended partition entries.

:roll:

for the encrypted partition, partimage can't be used I think.

Maybe
Code:
dd if=/dev/encr-dev of=/mnt/usb/partition-backup

Does your laptop have a network connection? The backups could be to big to store on a USB key

If you boot the laptop from the USB key, then your laptop partitions are not mounted. The partimage binary should be run from the USB key, or a drive not being backupped (The binary can be moved to tmpfs/ramdisk, if there's no space for it on the USB key. I used partimage booting from two 1.44 MB floppies once (1 with the kernel other with busybox+ramdisk).

for ~$10 US you can get an adapter to convert your laptop ide harddrive to a normal 40/80 wire ide cable and then you can stick it right into another computer if you have one

Ditto this, absolutely the fastest solution if you've ever done it before. There are cables that are USB->ide/laptop-ide also if you refuse to shutdown your desktop to plug it in.

For raw images I copy with "dd"

the adapter sounds great... but i have a s-ata drive...
are there adapters for those?

and what about a lan-drive? can partimage work with these?
(and any suggestion as to which one to choose?)

you have a s-ata laptop drive? (do they exist? what kind of connector is it) or a desktop HD?

For desktop: I was at a computer show last weekend and saw a ~20-30$ usb to combination: laptop pata, pata, sata
It was hard for me not to buy it, but I already have a usb->sata and a ide->laptop-ide (is there a technical term for the laptop-ide connector)?

Sadly I've never used partimage, only "cp -A" for mounted volumes and dd for raw backups so I cannot speak to that.

Let's not forget good old "tar" (cf. orange_juice). Good defragmentation also :-)

The filesystems can be whiped out by
Code:
# rm the files
# dd if=/dev/zero of=/mnt/root/bigfile; sync
# rm /mnt/root/bigfile; sync
etc.

Yes they exist, I have one too.

I don't know if the sata connection on the drive is compatible with desktop sata, as I've never tried anything wonky like that with it, but I can assure you that they exist.
