My experience with mondo was not good.
I did the DVD image but was impossible to restore the image.
Install a new RH environment is not difficult and short in time.
Provably the best idea is to perform a simple tar backup of the /etc and /home file systems.

you want offline backup then "dd" i guess.

when using 'dd' for disaster recovery purposes, don't forget to also save your partition layout with 'fdisk -l'

Shalom,

In the paid arena http://acronis.com works very well.

We use it for backups and system cloning.

Hi gobi,

We use "Mondo Rescue" for OS backup on tapes/DVD and it works fine. Its great tool like Ignite for HPUX.

I use mkcdrec tool :
you install it and configure easyly the Config.sh file
it makes an iso file that you must be burn on a CD or DVD
and you have your system on this media - you could start and install it after a crash.

I test it it's easy to use and reliable

try www.storix.com

They have different types of bootable backups. You can download and "play" for 30 days. You can also call 4 tech support as well. They DO respond because they want to sell.

o "standalone" This one works great.

o A TSM - I also tried this one but had difficulties. Not because of storix but because of bos software not on my aix tsm server.

o network - Didn't test this one

Well, there are several ways depending on your configuration. I have the luxury of this being my system at home, so I can take the time to do it this way.

I have 2 9GB disks on my FW-SCSI channel.
(Both are bootable)

I also have a USB 360GB disk.

I also have a DDS3 tape drive.

Once a month I do the following:

o I do a shutdown. (SDA is the booted disk)

o I reboot from the SDB disk.

o I mount the SDA disk at /previous_boot_disk

o I cd to it and tar the entire disk to either the tape or to the USB disk.

o I umount the SDA disk and reboot from it.

o I initialize the SDB disk (fdisk / mke2fs -f / fsck).

o I mount the SDB disk at /new_boot_disk.

o I do a umask 0.

o I cd to /new_boot_disk.

o I untar the tape or USB disk's file to it.

o I run LILO.

o I reboot on the SDB disk.

--

With this method:

o I know my original disk works.

o I know (or will find out) that my copy disk works.

o I know (or will find out) that the tar of my previously booted disk is good.

o I can take the tape and the USB disk offsite and know that if something happens that I have a known good backup.

Yeah - there are going to be people laughing themselves silly at my old style way of doing stuff - but it works great and it's cheap.

Hey - I still have a Toshiba T4850CT with a 520MB disk and a 37MHz CPU that is running the Linux 1.2 kernel! It ran for 2 1/2 years without an error!
