Configuration Backup

The xCat internal configuration can be saved with the dumpxCATdb command. It will create several CSV files with the database content. Please note that xCAT relies on several other files on the system that should be part of the backup.

$ /opt/xcat/sbin/dumpxCATdb -p /install/custom/backup/201609
