Zetaback is a thin-agent based ZFS backup tool. It is designed to:

    * run from a central host
    * scan clients for new ZFS filesystems
    * manage varying desired backup intervals (per host) for
          o full backups
          o incremental backups
    * maintain varying retention policies (per host)
    * summarize existing backups
    * restore any host:fs backup at any point in time to any target host
