Note: Using beadm Utility (Tasks)

You can use the beadm utility to create and manage snapshots and clones of your boot environments.

Note the following distinctions relevant to boot environment administration:

* A snapshot is a read-only image of a dataset or boot environment at a given point in time. A snapshot is not bootable.

* A boot environment is a bootable Oracle Solaris environment, consisting of a root dataset and, optionally, other datasets mounted underneath it. Exactly one boot environment can be active at a time.

* A clone of a boot environment is created by copying another boot environment. A clone is bootable.
