Usage Examples

Basic Operations

Standard Backup (Default)

./backup-immich.sh
# Performs complete backup with all default settings:
# - Backs up database and upload directory
# - Uploads to B2 if configured
# - Sends webhook notifications
# - Logs to /home/acedanger/shell/logs/immich-backup.log

Getting Help

./backup-immich.sh --help
# Shows complete usage information including:
# - All available command-line options
# - Configuration requirements
# - Examples and restore instructions

Preview and Testing

Dry Run (Preview Mode)

./backup-immich.sh --dry-run
# Shows what would be backed up without executing:
# - Checks all prerequisites and container status
# - Displays backup file paths and estimated sizes
# - Validates B2 configuration if present
# - Reports any issues that would prevent backup
# - No files are created or modified

Example dry-run output:

=== DRY RUN MODE - NO ACTUAL BACKUP WILL BE PERFORMED ===

Configuration:
  - Database: immich
  - Username: postgres
  - Upload Location: /opt/immich/upload
  - Container: immich_postgres
  - Backup Directory: /home/acedanger/shell/immich_backups

Would create:
  - Database backup: /home/acedanger/shell/immich_backups/immich_db_backup_20250527_140000.sql.gz
  - Upload backup: /home/acedanger/shell/immich_backups/immich_uploads_20250527_140000.tar.gz

Container Status Check:
  ✓ immich_server: Running (would pause during backup)
  ✓ immich_postgres: Running
  ✓ Upload directory: /opt/immich/upload (42GB)

B2 Upload Configuration:
  ✓ B2 configured - would upload to bucket: my-immich-backups
  ✓ B2 CLI found at: /home/acedanger/shell/immich/b2-linux

=== DRY RUN COMPLETE - No files were created or modified ===

Local Backup Only

Skip B2 Upload

./backup-immich.sh --no-upload
# Performs backup but skips B2 upload:
# - Creates local backup files

Automation Examples

Scheduled Backup (Crontab)

# Daily backup at 2:00 AM with logging
0 2 * * * /home/acedanger/shell/immich/backup-immich.sh >> /home/acedanger/shell/logs/immich-backup.log 2>&1

# Weekly local-only backup (no B2 upload) at 3:00 AM on Sundays
0 3 * * 0 /home/acedanger/shell/immich/backup-immich.sh --no-upload

# Daily validation run (dry-run) at 1:55 AM to check system health
55 1 * * * /home/acedanger/shell/immich/backup-immich.sh --dry-run >> /home/acedanger/shell/logs/immich-validation.log 2>&1

Manual Backup Scripts

#!/bin/bash
# emergency-backup.sh - Quick local backup without B2
echo "Starting emergency Immich backup..."
/home/acedanger/shell/immich/backup-immich.sh --no-upload --verbose

#!/bin/bash
# weekly-validation.sh - Comprehensive system check
echo "Validating Immich backup system..."
/home/acedanger/shell/immich/backup-immich.sh --dry-run --verbose

Troubleshooting Examples

Check System Status

# Quick system validation without backup
./backup-immich.sh --dry-run

# If containers are not running:
docker ps | grep immich  # Check container status
docker start immich_server immich_postgres  # Start if needed

# If upload directory missing:
ls -la /opt/immich/upload  # Verify path exists

Test B2 Configuration

# Backup without B2 to test local functionality
./backup-immich.sh --no-upload

# Check B2 CLI manually
./b2-linux version  # Verify B2 CLI works
./b2-linux authorize-account YOUR_KEY_ID YOUR_KEY  # Test authorization

Debug Backup Issues

# Run with maximum detail for troubleshooting
./backup-immich.sh --verbose --no-upload

# Check logs for errors
tail -f /home/acedanger/shell/logs/immich-backup.log

# Validate backup files
ls -la /home/acedanger/shell/immich_backups/

Configuration

The scripts expect a .env file in the parent directory with the following variables:

# Database configuration
DB_USERNAME=postgres
DB_DATABASE_NAME=immich
UPLOAD_LOCATION=/path/to/immich/uploads

# Notification settings
WEBHOOK_URL="https://notify.peterwood.rocks/lab"

# Backblaze B2 settings (optional)
# Get these from your B2 account: https://secure.backblaze.com/app_keys.htm
# B2_APPLICATION_KEY_ID=your_key_id_here
# B2_APPLICATION_KEY=your_application_key_here
# B2_BUCKET_NAME=your_bucket_name_here

# Optional: Backup retention (days)
BACKUP_RETENTION_DAYS=30

Backup Strategy

Based on Immich's official backup recommendations:

1. Database Backup: Uses pg_dumpall with --clean and --if-exists flags
2. Upload Directory: Complete archive of upload location including:
   • upload/ - Original photos and videos
   • profile/ - User profile images
   • thumbs/ - Generated thumbnails
   • encoded-video/ - Transcoded videos
   • library/ - Library metadata
   • backups/ - Existing backup files (excluded from new backups)

Notifications 🔔

The backup script sends notifications to your webhook URL with:

• 🚀 Start notification: When backup begins
• ✅ Success notification: When backup completes successfully with file sizes
• ⚠️ Warning notification: When backup succeeds but B2 upload fails
• 🚨 Error notification: When backup fails

Example notification:

📦 Database: immich_db_backup_20250526_215913.sql.gz (150MB)
📁 Uploads: immich_uploads_20250526_215913.tar.gz (25GB)
☁️ Successfully uploaded to B2 bucket: my-immich-backups

Backblaze B2 Integration ☁️

Setup B2 Account

1. Create a Backblaze B2 account
2. Create a new bucket for Immich backups
3. Generate application keys:
   • Go to: https://secure.backblaze.com/app_keys.htm
   • Create new key with read/write access to your bucket

Configure B2 in .env

Add these variables to your .env file:

B2_APPLICATION_KEY_ID=your_key_id_here
B2_APPLICATION_KEY=your_application_key_here
B2_BUCKET_NAME=your_bucket_name_here

B2 Features

• Automatic upload: Backup files are uploaded to B2 after creation
• Organized storage: Files stored in immich-backups/ folder in your bucket
• Error handling: Script continues if B2 upload fails (local backup preserved)
• Progress tracking: Upload status included in notifications

The B2 CLI tool (b2-linux) is included in this directory and doesn't require separate installation.

Restore Process

For complete restore instructions, see: https://immich.app/docs/administration/backup-and-restore/

1. Database Restore:

   docker exec -i immich_postgres psql -U postgres < immich_db_backup.sql
   

2. Upload Directory Restore:

   tar -xzf immich_uploads_backup.tar.gz -C /target/location
   

Logs

Backup logs and performance metrics are stored in the main shell logs directory (/home/acedanger/shell/logs/).

Monitoring

The backup script includes:

• Progress indicators for long-running operations
• Size validation for backup files
• Container status monitoring
• Automatic cleanup procedures
• Comprehensive error reporting
