+# Script Name: db2_zfs_backup.sh
+# Description: Creates a raw base backup of PostgreSQL on zcluster.technodrome2 using pg_basebackup in directory mode.

+# Requirements: pg_basebackup, SSH access, rclone or rsync, ZFS dataset available at destination
+# Usage: ./db2_zfs_backup.sh
+# Author: Doc @ Genesis Ops
+# Date: 2025-05-12
