zelta(8) System Manager's Manual zelta(8) NAME zelta - perform safe, recursive ZFS operations locally and remotely SYNOPSIS zelta -V | \--version | version zelta SUBCOMMAND [OPTIONS] [ARGUMENTS] DESCRIPTION zelta provides tools for ZFS replication, backup verification, dataset recovery, and policy-based automation. All operations work recursively on dataset trees and support both local and remote execution via ssh(1). Remote dataset endpoints follow scp(1) conventions. Operations can be performed without installing zelta on remote systems--only standard ZFS utilities and SSH access are required. Examples: Local: pool/dataset@snapshot Remote: user@example.com:pool/dataset@snapshot See zfs(8) for dataset naming conventions. SUBCOMMANDS For detailed usage of each subcommand, run zelta help or see the re- spective manual page. zelta -? Display help message. zelta -V, --version, version Display version information. Comparison zelta match source target Compare two dataset trees and report matching snapshots or dis- crepancies. See zelta-match(8). Replication zelta backup source target Replicate a dataset tree. Creates snapshots if needed, detects optimal send options, and replicates intermediate snapshots. See zelta-backup(8). Recovery zelta clone dataset target Create a writable clone of a dataset tree. See zelta-clone(8). zelta revert dataset Rewind a dataset to a previous snapshot by renaming and cloning. Preserves current state. See zelta-revert(8). zelta rotate source target Preserve divergent dataset versions through rename and clone op- erations. See zelta-rotate(8). Automation zelta policy [options] Execute replication operations based on configuration file defi- nitions. See zelta-policy(8). OPTIONS AND ENVIRONMENT Configuration follows a hierarchy from lowest to highest precedence: 1. Internal defaults 2. `/usr/local/etc/zelta/zelta.env` 3. Policy configuration (`zelta.conf`) 4. Environment variables 5. Command-line arguments See zelta-options(7) for details. FILES /usr/local/etc/zelta/zelta.conf Default policy configuration file. /usr/local/etc/zelta/zelta.env Global default setting overrides. EXAMPLES The following examples use "sink" as the source pool and "tank" as the backup target. Replicate a dataset to a remote host: zelta backup sink/data/project backupuser@backup-host.example:tank/backups/project Compare local and remote dataset trees: zelta match sink/data remote:tank/backups Revert a dataset to its previous snapshot: zelta revert sink/data/project Update a target that has diverged: zelta rotate sink/data/project backupuser@backup-host.example:tank/backups/project Back up everything defined in policy settings (zelta.conf). zelta policy EXIT STATUS Returns 0 on success, non-zero on error.
