Though a small operation, they seem to provide tools for doing Ignite style OS backups and restore.

A tar backup will not include certain types of files such as soft links and will probably not be usable.

Mondo is a great tool, it makes bootable recovery CDs.

But you must know that recovering from a tar backup is tedious.

So, install and use dump/restore to make backups. This is a preferred tool for making backups, and you can restore the system from the backup without reinstalling it.

Hi LeongKO

You can use rsync which has options to preserve links ou can also use this passing it to ssh to make it secure.

You can have a bootable cd live like knoppix to boot from in case of disaster, check that this live CD (zillions of them out there) has the tolls for partition creation and a compatible version of rsync to the one you use to backup the system to be used at restore time.

http://www.knoppix.org/

and have a look at man rsync, see if it fits you needs.

We use Microlite BackupEdge and are able to make recovery CD's as well as "clone" a new Redhat server from a "master" (so we can get a new server up and running in about 45 minutes).

hey

1. make a linux bootable floppy
2. boot the system with win98 bootable floppy or cd
3. use norton ghost to make the image file
4. write the image file to a the writable cd

if you want to restore,

boot with a win98 bootabl floppy or cd run norton ghost and convert the image to hdd.
and make the disk bootable

it should work

In my last post, I was wrong (very wrong).

Talking about command line utilities to make backups, dump/restore should not be used (shame). I though that will be as good as vdump/vrestore (tru64).

See:

http://lwn.net/2001/0503/a/lt-dump.php3

www.naspa.com/PDF/2002/1102%20PDF/T0211003.pdf

The star (unique standard tape archiver) command, should be used, because it supports extended headers, for backup acl and files in SELinux enabled systems.

Better late than never.

Cheers.
