primarily a duplicate of Red Hat's RPM repository, it can be regenerated with satellite-sync.

Red Hat recommends the entire /var/satellite/ tree be backed up. In the case of

disconnected satellites, /var/satellite/must be backed up.

Backing up only these files and directories would require reinstalling the RHN Satellite Server

ISO RPMs and reregistering the Satellite. In addition, Red Hat packages would need to be

resynchronized using the satellite-sync tool. Finally, you would have to reinstall the

/root/ssl-build/\ rhn-org-httpd-ssl-key-pair-MACHINE_NAME-VER-REL.noarch.rpm.

Another method would be to back up all of the files and directories mentioned above but

reinstall the RHN Satellite Server without reregistering it. During the installation, cancel or skip

the RHN registration and SSL certificate generation sections.

The final and most comprehensive method would be to back up the entire machine. This would

save time in downloading and reinstalling but would require additional disk space and back up

time.

4. Using RHN DB Control

RHN Satellite Server with Embedded Database requires a utility for managing that database.

Red Hat provides just such a tool: RHN DB Control. This command line utility allows you to do

everything from make, verify, and restore backups to obtain database status and restart it when

necessary. You must be the oracle user to invoke RHN DB Control. To begin, switch to the

oracle user:

su - oracle

Next, issue the following command:

db-control option

4.1. DB Control Options
