iSeries™ integration of a logical partition combines two operating systems (i5/OS® and the logical operating system). You may be able to use i5/OS or Linux utilities or a combination of both to manage back ups.
When you are planning your back up strategy, refer to Backup and Recovery, as well as Linux documentation. For information on backing up and recovering Linux partitions on eServer™ 5800 servers, refer to Backup and Recover Linux Installations.
