2. Go to Configuration → Access Control → API Tokens
3. Click Add
4. Configure:
   • User: root@pam
   • Token ID: backupAutomations (or any name)
   • Privilege Separation: Leave unchecked
5. Copy the secret immediately (shown only once!)

2. Grant Permissions:

1. Go to Configuration → Access Control → Permissions
2. Click Add → User Permission
3. Configure:
   • Path: /datastore/YOUR-DATASTORE-NAME
   • User: root@pam!backupAutomations
   • Role: DatastoreBackup

Usage

Installation Wizard

Run the tool and follow the prompts:

sudo PBSClientTool

You'll be asked for:

1. PBS Server: IP/hostname and port
2. Authentication: API token (recommended) or password
3. Backup Type:
   • File-level only (fast, selective restore)
   • Block device only (full disk image, bootable as VM)
   • Both (recommended) - Files daily + disk weekly
4. Schedule: When to run backups
5. Retention: How long to keep backups
6. Encryption: Optional (recommended for sensitive data)

The installer will test your connection and create automated backup services.

Multi-Target Management

After installation, you can manage multiple backup targets:

Main Menu Options:

1. List all backup targets - View all configured servers
2. Add new backup target - Configure additional PBS server
3. Edit existing target - Update connection/settings
4. Delete target - Remove a backup destination
5. Run backup now - Test or run immediate backup
6. Reinstall PBS client - Reinstall the backup software
7. Exit

Running Backups

Scheduled (automatic):

# Check timer status
sudo systemctl status pbs-backup-default.timer

# View next scheduled run
sudo systemctl list-timers pbs-backup-*

Manual (on-demand):

# Via menu (recommended - shows live progress)
sudo PBSClientTool
# Select option 5 (Run backup now)

# Via systemd
sudo systemctl start pbs-backup-default-manual.service

# Direct script execution
sudo /etc/proxmox-backup-client/backup-default.sh

Viewing Logs

# View recent backup logs
sudo journalctl -u pbs-backup-default.service -n 50

# Follow logs in real-time
sudo journalctl -fu pbs-backup-default.service

# List all backups on server
sudo -E proxmox-backup-client snapshot list

Command-Line Options

sudo PBSClientTool --help       # Show help
sudo PBSClientTool --version    # Show version
sudo PBSClientTool --install    # Install to system

Configuration Files

Multi-target setup:

• /etc/proxmox-backup-client/targets/TARGET.conf - Target configurations
• /etc/proxmox-backup-client/backup-TARGET.sh - Backup scripts
• /etc/systemd/system/pbs-backup-TARGET.{service,timer} - Systemd units

Encryption key:

• /root/.config/proxmox-backup/encryption-key.json - Main key
• /root/pbs-encryption-key-*.txt - Paper backup (print and secure!)

Backup Types Explained

File-Level (.pxar)

• Fast - Usually completes in 2-5 minutes
• Selective - Restore individual files/folders
• Efficient - Deduplication and compression
• Best for: Daily backups, quick recovery

Block Device (.img)

• Slow - Can take 20-30+ minutes
• Complete - Entire disk image
• Bootable - Can restore as VM on Proxmox
• Best for: Weekly backups, disaster recovery

Hybrid (Both)

• Recommended - Best of both worlds
• Files backup daily (fast, efficient)
• Disk image weekly (complete system backup)
• Configure separate schedules for each

Encryption Key - Important!

⚠️ Your encryption key is the ONLY way to restore encrypted backups!

If you lose the key, your backups are permanently unrecoverable.

Best practices:

1. Print the paper backup immediately (/root/pbs-encryption-key-*.txt)
2. Store printed copy in safe location (fireproof safe, safety deposit box)
3. Copy encryption-key.json to password manager
4. NEVER store key on the same system being backed up
5. Test key restoration regularly

Updating PBSClientTool

cd ~/dev/PBSClientTool
git pull
sudo ./pbs-client-installer.sh --install
# Confirm overwrite: yes

Your backup targets and configurations are preserved during updates.

Uninstallation

Remove command only (keeps backups and configs):

sudo PBSClientTool --uninstall

Complete removal (removes everything):

cd ~/dev/PBSClientTool
sudo ./uninstaller.sh
