zelta-clone(8) System Manager's Manual zelta-clone(8) NAME zelta clone - Perform a recursive clone operation. SYNOPSIS zelta clone [-d depth] [initiator] source/dataset target/dataset DESCRIPTION zelta clone performs a recursive zfs clone operation on a local or in- dicated host. By default, it wil clone the most recent dataset and all of its descendents. The target dataset must not exist. By default, the topmost dataset property readonly=off will be set. Note that ZFS cloning will reset (inherit) mountpoints. Clones must be created on the same pool as the source dataset. When cloning, the source can be readonly and not mounted, making cloning excellent for backup inspection as well as recovery of a dataset from a specific snapshot. If using zelta clone for recovery, consider using zelta backup -rotate to replicate the cloned dataset state to its backup replicas. OPTIONS A source and target dataset parameter are required. source/dataset A dataset, in the form pool[/component][@snapshot], which will be cloned along with all of its descendents. If a snapshot is not given, the most recent snapshot will be used as the clone origin. target/dataset A dataset, which must be on the same pool as the source/dataset, where the clones will be created. This dataset must not exist. initiator A remote host, accessible via SSH, where the clone commands will be executed. -snapshot Snapshot before cloning. See zelta.env.example to adjust the naming scheme. -n, -dryrun Don't clone, but show the zfs clone commands that would be exe- cuted. -q Reduce verbosity. -v Increase verbosity. -d depth, -depth depth Limits the depth of all Zelta operations. EXAMPLES The target clones can be destroyed without affecting their source. Af- ter cloning a dataset with a remote replica, zelta backup -rotate Clone a dataset tree for inspection: zelta clone tank/vm/myos tank/temp/myos-202404 Recover a dataset tree, in place, to a previous snapshot's state: zfs rename tank/vm/myos tank/Archives/myos-202404 zelta clone tank/Archives/myos-202404@goodsnapshot tank/vm/myos Dry Run: Display the zfs clone commands without executing them. zelta clone -n tank/source/dataset tank/target/dataset SEE ALSO ssh(1), zelta(8), zelta-backup(8), zelta-match(8), zelta-policy(8), zfs(8), zfs-clone(8), zfs-promote(8) AUTHORS Daniel J.
