Proxmox Backup Server (PBS) Integration

This guide explains how to connect Pulse to your Proxmox Backup Server for comprehensive backup monitoring.

Two Ways to Monitor PBS Backups

Pulse can monitor PBS backups in two ways:

1. Direct PBS Connection (Recommended)

Connect directly to your PBS server for full monitoring capabilities:

Benefits:

• ✅ Deduplication factor and storage efficiency stats
• ✅ PBS server health monitoring (CPU, memory, uptime)
• ✅ Datastore usage and namespace hierarchy
• ✅ Sync, verify, prune, and GC job status
• ✅ Backup owner information
• ✅ Faster queries (no PVE proxy overhead)

2. PVE Passthrough (Automatic)

If your PVE cluster has PBS storage configured, Pulse automatically fetches backup data through the PVE API.

Limitations:

• ❌ No deduplication stats
• ❌ No PBS server health data
• ❌ No job monitoring
• ❌ Can be slow for encrypted PBS storage
• ❌ Limited metadata per backup

Recommendation: If you see a banner in the Backups page suggesting you add PBS directly, following this guide will significantly improve your monitoring experience.

Setting Up Direct PBS Connection

Method 1: Agent Install (Recommended)

Install the Pulse agent directly on your PBS server for automatic setup:

# Run on your PBS server
curl -sSL https://your-pulse-server/api/pulse-agent-install?type=pbs | sudo bash

The agent will:

1. Detect it's running on a PBS server
2. Create a pulse-monitor@pbs user with read-only access
3. Generate an API token
4. Register the PBS node with Pulse automatically

Method 2: One-Click Setup Script

From Pulse's Settings page:

1. Go to Settings → Nodes
2. Click Add PBS Node
3. Select API Only tab
4. Enter your PBS server's URL
5. Click copy to get the setup command
6. Run the command on your PBS server

Method 3: Manual Token Creation

If you prefer manual setup:

# SSH into your PBS server

# 1. Create a dedicated monitoring user
proxmox-backup-manager user create pulse-monitor@pbs --comment "Pulse monitoring"

# 2. Grant read-only access (Audit role)
proxmox-backup-manager acl update / Audit --auth-id pulse-monitor@pbs

# 3. Generate an API token (save the output!)
proxmox-backup-manager user generate-token pulse-monitor@pbs pulse-token

Copy the token value and enter it in Pulse:

• Token ID: pulse-monitor@pbs!pulse-token
• Token Value: The UUID shown after running the command

PBS Permissions

The Pulse monitoring user needs minimal permissions:

Role	Path	Purpose
Audit	/	Read-only access to all datastores, backups, and server status

The Audit role provides:

• List datastores and their usage
• View backup groups and snapshots
• Read server status (CPU, memory, uptime)
• View job history and status

It does not allow:

• Creating, modifying, or deleting backups
• Running backup/restore operations
• Changing server configuration

---

Multiple PBS Servers

If you have multiple PBS servers, add each one separately in Settings. Pulse will:

• Monitor each server independently
• Show backups from all servers in the unified Backups view
• Deduplicate if the same backup appears via both PVE passthrough and direct PBS

---

Troubleshooting

"Connection Failed" Error

1. Check URL: Ensure the PBS URL is correct (default port is 8007)

   • Format: https://pbs.example.com:8007

2. Verify token: Test authentication:

   curl -sk -H "Authorization: PBSAPIToken=pulse-monitor@pbs!pulse-token:YOUR_TOKEN" \
     https://your-pbs:8007/api2/json/version
   

3. Network access: Ensure Pulse can reach PBS on port 8007

4. SSL verification: If using self-signed certificates, disable SSL verification in the node settings

Slow Backup Loading

If you notice slow loading for PBS storage accessed via PVE:

• This often happens with encrypted PBS datastores
• The fix is to add PBS directly (this guide)
• Direct PBS connections bypass the slow PVE content listing

Duplicate Backups

If you see the same backup twice:

• This shouldn't happen—Pulse deduplicates by VMID and timestamp
• If it does occur, the direct PBS version takes priority
• Check console for debug logs: localStorage.setItem('debug-pmg', 'true')

---

Data Source Indicator

In the Backups view, PBS backups show a data source indicator:

• "PBS" badge alone = Direct PBS connection (full data)
• "PBS via PVE" = Passthrough via PVE storage (limited data)

Adding your PBS server directly will remove the "via PVE" indicator and unlock full monitoring capabilities.
