ZFS-CLONE(8)		     System Manager's Manual		    ZFS-CLONE(8)

NAME
     zfs-clone -- clone snapshot of ZFS dataset

SYNOPSIS
     zfs clone [-pu] [-o property=value]a| snapshot filesystem|volume

DESCRIPTION
     See the "Clones" section of zfsconcepts(7) for details.  The target dataset
     can  be  located  anywhere in the ZFS hierarchy, and is created as the same
     type as the original.

     -o property=value
	     Sets the specified property; see zfs create for details.

     -p      Creates all the non-existing parent datasets.  Datasets created  in
	     this  manner  are automatically mounted according to the mountpoint
	     property inherited from their parent.  If the target filesystem  or
	     volume already exists, the operation completes successfully.

     -u      Do not mount the newly created file system.

EXAMPLES
   Example 1: Creating a ZFS Clone
     The following command creates a writable file system whose initial contents
     are the same as pool/home/bob@yesterday.
	   # zfs clone pool/home/bob@yesterday pool/clone

   Example 2: Promoting a ZFS Clone
     The following commands illustrate how to test out changes to a file system,
     and  then	replace  the  original	file  system with the changed one, using
     clones, clone promotion, and renaming:
	   # zfs create pool/project/production
	     populate /pool/project/production with data
	   # zfs snapshot pool/project/production@today
	   # zfs clone pool/project/production@today pool/project/beta
	     make changes to /pool/project/beta and test them
	   # zfs promote pool/project/beta
	   # zfs rename pool/project/production pool/project/legacy
	   # zfs rename pool/project/beta pool/project/production
	     once the legacy version is no longer needed, it can be destroyed
	   # zfs destroy pool/project/legacy
