DD command to backup and restore
Hi,
Currently I have 2 servers. 1 is already installed with RHEL4(withmyapplications) and the other one is still brand new.
My question is, is it possible to use DD command to backup the whole harddrive for the RHEL4 server and restore it to the new brand server so that I do not have to install it and do the works again from the start.
and if my RHEL4 server is HP prolliant and the 'brand new' server is Sun Microsystems server. is it possible to use the dd command to clone the whole disk and restore it using DD?
Because I did search using a search button on top and came up with this thread about DD, and it seems like it can not be done if I use two different servers or different harddisk brand and size.

I have no idea whether it will bring any difference. Your help is greatly appreciate!
Thank You guys in advance.

I backed up a unix database using
"tar -cvf /dev/rmt1 -N 800 /*"
Normally I would restore this using
"tar -xvf /dev/rmt1 -N 800"
This is reporting an error about
"not enough memory"
I have done a new test backup and restore using the same commands and they work.
ANY IDEAS ? (2 Replies)

NAME
brandelf -- mark an ELF binary for a specific ABI
SYNOPSIS
brandelf [-lv] [-f ELF_ABI_number] [-t string] file ...
DESCRIPTION
The brandelf utility marks an ELF binary to be run under a certain ABI for FreeBSD.
The options are as follows:
-f ELF_ABI_number
Forces branding with the supplied ELF ABI number. Incompatible with the -t option. These values are assigned by SCO/USL.
-l Writes the list of all known ELF types to the standard error.
-v Turns on verbose output.
-t string
Brands the given ELF binaries to be of the string ABI type. Currently supported ABIs are ``FreeBSD'', ``Linux'', and ``SVR4''.
file If -t string is given it will brand file to be of type string, otherwise it will simply display the branding of file.
EXIT STATUS
Exit status is 0 on success, and 1 if the command fails if a file does not exist, is too short, fails to brand properly, or the brand
requested is not one of the known types and the -f option is not set.
EXAMPLES
The following is an example of a typical usage of the brandelf command:
brandelf file
brandelf -t Linux file
