Using a media device assigned to the same partition
Local backups are backups that are performed to a device that is physically
attached to the machine and, in this case, the partition. This type of backup is the
easiest to implement. Figure 20-10 on page 659 illustrates the relationship
between partitions and their respective backup devices for a cloning operation.

Sample backup to DVD
Make sure that you have evaluated any additional hardware resources that will
exist on the destination partition and install the needed device drivers to support
them before performing the backup.
To execute a full system (installation image) backup of this partition to be used
only to reinstall this partition or another partition on this machine, pointing the
backup to the /dev/cd1 device, which uses 2.6 GB media, issue the following
command:
# /usr/sbin/mksbcd -T “D” -t I -f /dev/cd1 -Z 2662
Starting with SysBack Version 5.6.5.0, you can create backups using the UDF
structure on DVD media when using AIX 5.2 and later (as opposed to ISO9660).
Issue the following command to use the UDF format:
# /usr/sbin/mksbcd -T “D” -t U -f /dev/cd1 -Z 2662
Sample boot and install from DVD
To boot and install from a DVD, do the following operations:
1. Place the DVD backup in the drive and activate your partition to begin
booting.
Note: A backup to CD/DVD has additional configuration requirements. There
are also many additional flags, options, and potential considerations of the
/usr/sbin/mksbcd
command. See the
/usr/lpp/sysback/README.udf.dvdcd.txt file for details about using this
feature.
