Backup Strategies#

1. Backrest & Restic Google Drive Backup#

Encrypts TrueNAS/DSM network shares with Restic and stores them in Google Drive through Rclone. See Backrest & Restic Google Drive Backup Setup.

2. Proxmox PBS Backup to Google Drive#

Synchronizes the deduplicated PBS datastore from the UNAS-Pro NAS to Google Drive through MMDocker and Rclone. See Proxmox - PBS Backups via NAS with to GDrive.

3. UNAS-Pro to TrueNAS Rsync Pull Backups#

TrueNAS nodes pull shared data from UNAS-Pro on staggered hourly schedules into local ZFS datasets. See Unifi UNAS-Pro Backup Strategy.

UniFi UNAS-Pro Master Backup Strategy: Native Rsync Daemon (Pull) Architecture#

This document defines the complete operational standard, architecture, schedule matrix, node-by-node configuration reference, and disaster recovery procedures for backing up all shared data from the master UniFi UNAS-Pro NAS (10.1.2.2) across the fleet of 5 TrueNAS SCALE storage nodes (HP1, HP2, HP3, HP7, HP8). It is designed to be sufficient to fully reconstruct the entire setup from scratch.

UNAS-Pro Backup Migration Plan: SMB (Push) to Native Rsync Daemon (Pull)#

Antigravity Chat: agy –conversation=4c0c9b6d-2722-4fd6-a4aa-638c75ab46f4

This document is the complete master migration plan for transitioning the UNAS-Pro backup strategy from the UniFi Drive UI-managed SMB (Push) setup to a Native Rsync Daemon (Pull) model.

Because the UniFi Drive UI natively supports Rsync server settings and shared folder modules, migrating to Rsync requires configuring your TrueNAS SCALE servers (HP1, HP2, HP3, HP7, HP8) to pull the backups directly from the UNAS-Pro Rsync daemon over TCP port 873.

NAS Backup Pipeline: Backrest, Restic & Google Drive#

Complete configuration guide for backing up isolated TrueNAS/DSM network shares from the headless Ubuntu VM (HP1Docker) to an encrypted Google Drive repository using Backrest (a Web UI wrapper for Restic) and Rclone. For baseline Rclone installation, remote management, and CLI commands, see the RClone Guide.

1. System Architecture Overview#

• Source Data: 8 explicit network shares mounted via CIFS/SMB on the host VM at /mnt/<ShareName>.
• Backup Host: Ubuntu VM (HP1Docker - 10.1.2.202).
• Backup Agent: Backrest Docker Container running Restic 0.18.1.
• Target Backend: Google Drive (proxmox.app@gmail.com) via a dedicated Rclone remote.
• Security Model: Client-side, zero-knowledge encryption via a dedicated repository password before data leaves the local host.
• Rate-Limit Protections: Powered by a custom Google Cloud Project ID to bypass global multi-user API query restrictions during multi-terabyte data transfers.

2. Directory Structure Setup#

All configuration and container runtime files are centralized on the host under the user deployment directory.
