Redhat 8.0 recovery
Posted 22 July 2003 - 04:40 PM
I am very new to redhat and attempting to create a backup of one system that can be recovered to another system of the same type and configuration.
Attempted to use tomsrtbt and when I attempt to recover my dd created tape it does not see my /dev/sda
also have attempted to use.. HAL91 -- minimalistic Linux distribution
which says you can install modules but I have not been able to get the optional kernel modules to install keep getting out of space.. arg...
this is frustrating shouldn't be this hard. Any ideas or suggestions would be greatly appreciated.

First get the Gentoo LiveCD and follow the instructions I posted in this thread (and are replicated in the Gentoo install guide) to mount your various Linux partitions however instead of mounting them all and then chrooting, mount them one by one and, using another device with enough capacity to hold the rather large tar files created by this process, tar the contents of each partition like so:
cd /mnt/gentoo tar czvf /path/to/temp/device/partitionname.tgz . umount /mnt/gentoo mount /next/partition ..
Recovering the system is the exact reversal of the backup procedure (with the addition steps of mounting the device holding the tar files) except for one important step: you have to add 'p' to your tar parameters to ensure permissions are restored with the files:
tar -zxvpf /path/to/file/partitionname.tgz

The option above looks good but we are just trying to find a fast down and dirty way to do the following:
Load Redhat on a system.
Update the kernel as needed for our 3rd party application.
Install the third party application.
Do some configuration.
backup /dev/sda1 and /dev/sda3 to tape
go to a new machine
use raid manager to configure the disk the same as the last system
recover /dev/sda1 and /dev/sda3 from the tape
Any assistance is greatly appreciated.
