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

NAME

     zfs-clone - clone snapshot of ZFS dataset

SYNOPSIS

     zfs clone [-pu] [-o property=value]<?> 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
