System Backups with mksysb

• Creates a complete backup of rootvg.
• If image is saved to tape, the tape is bootable and can be used to completely clone the machine.
• If you need to restore a mksysb image to a machine of a different architecture than the one you made the image on (e.g., POWER-2 to PowerPC), you must use a special clone disk.
• You can also set up a NIM (Network Installation Management) server for network installs.
