• Backing up and cloning AIX: mksysb, savevg, and low-risk upgrades with alt_disk_copy

  mksysb creates a bootable backup of rootvg (savevg backs up a non-root volume group, not bootable, restored with restvg); lsmksysb reads back what a mksysb image contains without restoring it. alt_disk_copy and alt_disk_mksysb clone or update rootvg onto a spare disk so a bootlist change, not a restore, is the fallback if the new level misbehaves.
