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
