Does rysnc works for this?
Jacky, Jack
I am going to plan to make a backup with a old server.
Previously, my guys told me that when using dd for clone like command
to make the clone results in hard disk corruption.
I am planning to work like this:
On the new machine:
1. Boot from live cd for else that supports networking.
2. Mount the local hard drive and format as ext3 (label: /)
3. rysnc the old machine root (/) to the new one.
Two machine hardware configuration is identicial, I would like to ask,
does it work?

dd might work like a charm...
Had some controller issues on a Wintendo. Installed old and new disk in a
lab computer. Booted a Linux live CD. Used dd to copy the old 40G SCSI HD
onto a new 150G SATA. Created a new NTFS-partition for extra space for
home folders. Installed the SATA disk into the Wintendo box and booted. I
then moved the home folders, but that's another story...

4. Install bootloader. (man grub-install)
5. Check /etc/udev for rules that might change expected device names. (On
my workstation, changing /etc/udev/rules.d/z25_persistent-net.rules is
critical in order to make networking work from first boot)

YES..!

If everything seems under control, you're just not going fast enough.

I've done this.
* dd is, overall, fine, but takes a bloody loonger time to run and isn't
trivially resized to larger disks.
* rsync will not bring over the boot loader. For that, you may need to either
'dd' the boot loader and the '/boot' partition if you have a separate one,
which is easy to do, or boot with that live CD on the new box, mount the / and
/boot partitions, do a 'chroot' to the mounted /, and run 'grub-install'
