For tools, see:

www.systemimager.org/

For simple backup with commands, use star with the -xdev option to save each filesytem, like:

star c -xdev -sparse -acl f=/dev/nst0 /
star c -xdev -sparse -acl f=/dev/nst0 /usr
star c -xdev -sparse -acl f=/dev/nst0 /var
star c -xdev -sparse -acl f=/dev/nst0 /home
star c -xdev -sparse -acl f=/dev/nst0 /oracle
star c -xdev -sparse -acl f=/dev/nst0 /oradata

The star command is not installed by default.

1-For restoration, i must install OS and then restore these files ?
How can i restore them (commands) ?
2-Is "star" command a package that i must download or it exists in the redhat install cds ?

You don't need to install the OS, you can boot with the CD and start in rescue mode to restore the files. Also, I think that your system still will be bootable, so boot in single user and restore the files.

The star package comes with Fedora Core 4, i'm not sure if is available on the Red Hat Enterprise 3 CD's.

Just remember to save every filesytem listed in the df -t ext3 output.

Also, when restoring (if needed), use the -U and -p options. See the man page.

Cheers.
