zsnapd

ZFS Snapshot Daemon written in python

Description

Python daemon that manages ZFS snapshots and send/receive backup. Based on zfs-snap-manager.

* Remote ZFS snapshoting/aging wnd replication back to central ZFS

backup server. Only need to install zfs-utils, zsnapd-rcmd (for secure)

remote ssh key login and sshd on client, and use root ssh key based

* Has connectivity test to skip scheduled actions when the remote site

cannot be contacted. Actually quite useful for ZFS backing up laptops.

Reachability failures are logged of course!

* Uses Python3

* Native systemd support.

* Configuration is stored in configuration files with the ini file

format. Configuration .d parts directories also present

* Triggers the configured actions based on time or a '.trigger' file

present in the dataset's mountpoint.

* Can take snapshots (with a yyyymmddhhmm timestamp format).

* Can replicate snapshots to/from other nodes.

* Push based when the replication source has access to the replication

target.

* Pull based when the replication source has no access to the replication

target. Typically when you don't want to give all nodes access to the

backup/replication target.

* Cleans all snapshots with the yyyymmddhh timestamp schmea format based

on a GFS schema (Grandfather, Father, Son). Timestamp

evaluation based on actual ZFS snapshot creation metadata.

* Supports pre and post commands.
