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 SEE ALSO zfs-promote(8), zfs-snapshot(8) FreeBSD 14.1-RELEASE-p8 March 16, 2022 FreeBSD 14.1-RELEASE-p8
