20.2.2 System installation options
SysBack provides the following installation options from a full system (installation
image) backup:
Full system installation
This process reinstalls the system by recreating the rootvg volume group and,
optionally, any non-rootvg volume groups.
Recovery installation
This process restores the system on the / (root) and /usr file systems after
booting into maintenance mode. It is most useful in situations where you need
to back out software installations or changes without impacting your other
rootvg file systems.
Both of these installation types can be either prompted or unprompted:
Prompted
This is the default SysBack installation method. The system or partition is
booted from SysBack media to the SysBack Installation and Maintenance
Main Menu. You can then change or customize any installation option before
initiating the installation process.
Unprompted
By pre-configuring certain tasks required for an installation, such as defining
the console and terminal type, you can initiate an installation that requires no
human intervention. In this situation, you will not be prompted to complete any
customization through the SysBack Installation and Maintenance Main Menu.
Customizing an installation
During a prompted installation, all of the following tasks can be customized
through the SysBack Installation and Maintenance Main Menu options:
Change between the 32-bit and 64-bit kernels.
Change between JFS and JFS2.
Turn mirroring on or off and set the number of copies.
Specify to recreate, ignore, or delete non-rootvg volume groups on the
backup.
Specify whether to restore files as non-sparse.
Change any volume group attributes.
Designate a disk as a hot spare.
Change file system attributes or specify a file system to be ignored on restore.
