ZFS-CLONE(8) FreeBSD System Manager's Manual ZFS-CLONE(8)
NAME
zfs-clone - clone snapshot of ZFS dataset
SYNOPSIS
zfs clone [-p] [-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.
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
