There are a number of ways of doing backup and restore of RHEL fileystems. What you use depends on your configuration and how you wish to do backups.

For example, if you have an XFS filesystem, you could use xfsdump and xfsrestore.

For LVM, you could use vgcfgbackup and vgcfgrestore, lvmdump, lvmsnapshot and more.

For ext3/4, you could use dd, tar, cpio, pax and lots more.

NAME
yum-debug-dump - write system RPM configuration to a debug-dump file SYNOPSIS
yum-debug-dump DESCRIPTION
yum-debug-dump is a program which creates a gzipped file containing a lot of information useful to developers trying to debug a problem. By default it will output a file to the current working directory named yum_debug_dump-<hostname>-<time>.txt.gz. This file contains no pri- vate information but does contain a complete list of all packages you have installed, all packages available in any repository, important configuration and system information. You can view this file using the 'zless' command. You can use the coresponding program yum-debug-restore to act on this file and restore a set of packages (much like dump/restore). FILES
As yum-debug-dump uses YUM libraries for retrieving all the information, it relies on YUM configuration for its default values like which repositories to use. Consult YUM documentation for details: /etc/yum.conf /etc/yum/repos.d/ /var/cache/yum/ SEE ALSO
yum-debug-restore (1) yum.conf (5) http://yum.baseurl.org/ AUTHORS
See the Authors file included with this program. BUGS
There are of course no bugs, but should you find any, you should first consult the FAQ section on http://yum.baseurl.org/wiki/Faq and if unsuccessful in finding a resolution contact the mailing list: yum-devel@lists.baseurl.org. To file a bug use http://bugzilla.redhat.com for Fedora/RHEL/Centos related bugs and http://yum.baseurl.org/report for all other bugs. Seth Vidal 28 April 2008 yum-debug-dump(1)
