Rolling Back
You can replace a folder or LUN with an earlier version by rolling back to a snapshot. When
you roll back to a snapshot, the entire folder or LUN is replaced with the version captured by
the snapshot. All snapshots that were taken after the snapshot that was used for rolling back
are deleted. For information about how to roll back to a snapshot, see

Clones
You can copy a snapshot to become a new independent data set (that is, a new share or
LUN). Changes made to the clone do not affect the parent (“origin”) and changes made to the
parent do not affect the clone. To handle storage in an efficient way, common blocks of data
between the parent and the clone are shared. Because the clone is linked to the parent in this
way, the parent cannot be deleted when a clone exists. Additionally, the clone cannot be
migrated to a volume that does not contain the parent. For information about how to clone
snapshots, see
