Description

zfs-replicate sends all ZFS snapshots to a remote host via SSH. zfs-replicate does not create ZFS snapshots.

zfs-replicate is based on autorepl.py used by FreeNAS.

zfs-replicate is related to several other projects which fit other niches:

1. sanoid: A full snapshot management system. Its companion application, syncoid, handles replication with many available options.
2. zfs-replicate (BASH): A very similar project. The major differences are configuration style (our project uses parameters whereas this project uses a BASH script), and the system expectations (e.g., logging controls).
3. znapzend: Another scheduling and replicating system.
4. zrep: A SH script with several control commands for snapshot replication.
