ZFS Snapshot Daemon written in python
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
log in.
* 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/
* 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.
