A Unified Archive type is a collection of archive attributes which serve a common use case. The two types of Unified Archive types are clone and recovery.
Both clone archives and recovery archives are created and managed by the archiveadm command. This command provides for selection of zones to be included or excluded from an archive, as well as allowing for ZFS dataset exclusion.
By default, an archive includes all datasets associated with the selected zones, unless they are specifically excluded during the archive creation process. For a non-global zone, the archive will contain the zone boot environment datasets and all delegated datasets assigned to it. For a global zone, the boot environment datasets are archived as well as all datasets not associated with a zone. Note that process includes entire top-down pools. Any number of datasets may be excluded from the archive. See Unified Archives Creation for more information.
