Dear All

If someone knows that which software can be used to make a ghost
image for
the SUSE Linux ..

That will make me more easier to install the OS ..

I had tried to use the Symantec Ghost to make a disk to disk
image,but when
I restored the image ,the system could not be started :(

If you have some experience about this ?

Hi Kalvin,

Use dd - boot with a live DVD. If for example you have an external usb
drive and an internal ata drive then use:

dd if=/dev/hda of=/dev/sda bs=8257536

(this will clone an entire drive - after a lot of sampling found that
bs 8 mb factor was optimal - you can also set hdparm on /dev/hda fo
c1,d1 and u1)

you can also back only those partitions you want - similar as above -

dd if=/dev/hda1 of=/dev/sda1 bs=8257536

Rgds. Otto Rodusek.
How would I clone a system, but only the files / inodes, if I want to
use it on a different HDD? Let's say I have setup a 80GB HDD, with 3
partitions /, /home & /opt and I want to clone it for later use, but in
2 years time I may want to use a 250GB HDD, so the partitioning could be
different then.

You can do this as a file backup with tar, for example.

However, I find it simpler and much more convenient to easily "snapshot"
the partition as a whole.

If dd is not sufficient for that, partimage will be your friend.

In order to restore to a larger disk, later on, qtparted will be handy
(by enlarging the former smaller partition to it's then actual size).

This will only be difficult in the unlikely event that you want to
restore to a "smallerthantoday" partion, later on.
As Operating Systems and Harddisks sizes tend to grow I decided not to
worry about that. ;-))


regards
Eberhard
