NAME

zelta - Perform remote and recursive ZFS operations

SYNOPSIS



    zelta SUBCOMMAND

DESCRIPTION

zelta simplifies zfs tasks involving a datasets and their children (“dataset trees”) on local or remote systems. Most zelta subcommands accept a source and target dataset or remote dataset endpoint accessible via ssh(1).

See the zfs(8) manual for more information about dataset names. A source dataset may be pool name (a single element).

Remote dataset endpoints are defined similar to the scp(1) command in the form [user@]host:[dataset].

A local dataset:

apool
apool/filesystem
apool/filesystem@snapshot
apool/filesystem/volume
apool/filesystem/volume#bookmark

A remote dataset endpoint:

twin@example.com:apool
twin@example.com:apool/volume@snapshot
example.com:bpool/filesystem

SUBCOMMANDS

Zelta’s parameters attempt to follow ZFS conventions whenever possible.

zelta help

zelta -?: Displays a help message.

zelta -V, –version

zelta version: Displays the Zelta suite version

Comparison

See zelta-match(8) for more details.

zelta match: Describe the difference between dataset trees.

Replication & Cloning

Note that zelta is designed to be a safe and efficient backup tool that overides ZFS’s destructive and obtrsive operations by default. For detail see zelta-backup(8) or the Zelta Wiki.

zelta backup: Replicate a dataset tree. By default run extra commands to detect optimal zfs send options, snapshot if necessary, and replicate as many intermediate datasets as possible.
zelta sync: Replicate a dataset tree. By default, assume an up-to-date versions of ZFS and replicate only the most recent snapshot.
zelta clone: Clone and mount a dataset tree.

Policy-based Replication

zelta policy: Use zelta.conf to replicate dataset trees using a configuration file.

Other Zelta Functions

The following are additional Zelta utilities that are used internally and/or haven’t been designed for public use.

zelta enpoint: Validate and split an endpoint definiton.
zelta report: An example API reporter.
zelta sendopts: Determine compatible zfs send options between two hosts.
zelta snapshot: Create a recursive snapshot.
zelta time: If time(1) is unavailable, Zelta will use bash’s POSIX time function to time for precision reporting.
