geek-at / zfs_sync.php
Created Feb 28, 2022
PHP script that syncs remote ZFS snapshots to local dataset. Works with encrypted volumes
View zfs_sync.php
Script that syncs remote zfs snapshots to a local zfs target.
Can sync remote encrypted datasets without ever needing to know the key on the local machine.
It will automatically search for the last snapshot in common with the remote host and only sync the differences.
If it doesn't find any local ones or has none in common, it will sync the oldest snapshot of the remote machine.
Meant to be run as cronjob
