Chapter 8. Maintenance568.4.2. Backing up the DatabaseRed Hat recommends performing nightly backups of the Embedded Database and moving theresulting directory to another system via NFS, SCP, FTP, etc. Preferably, this backup system residesoff-site. To conduct a backup, shut down the database and related services first by issuing thefollowing command as root:service rhn-satellite stopThen switch to the oracle user and issue this command to initiate the backup:db-control backup DIRNAMEBackup files are stored in the directory specified. Note that this is a cold backup; the database must bestopped before running this command. This process takes several minutes. The first backup is a goodindicator of how long subsequent backups will take.Once the backup is complete, return to root user mode and restart the database and related serviceswith the following command:service rhn-satellite startYou should then copy that backup to another system using rsync or another file-transfer utility.
