+# Immich Backup Enhancement Summary
+
+## Date: May 26, 2025
+
+## Overview
+
+Enhanced the Immich backup script with notification system and Backblaze B2 cloud storage integration, following the same pattern as the existing Plex backup script.
+
+## New Features Added
+
+### 🔔 Webhook Notifications
+
+- **Start notification**: Sent when backup begins
+- **Success notification**: Sent when backup completes with file details
+- **Warning notification**: Sent when local backup succeeds but B2 upload fails
+- **Error notification**: Sent when backup process fails
+- **Rich content**: Includes file names, sizes, and emojis for better readability
+
+### ☁️ Backblaze B2 Integration
+
+- **B2 CLI tool**: Downloaded and installed `b2-linux` v4.3.2 in immich directory
+- **Automatic uploads**: Both database and upload archives are uploaded to B2
+- **Organized storage**: Files stored in `immich-backups/` folder in B2 bucket
+- **Error resilience**: Script continues if B2 upload fails (local backup preserved)
+- **Configuration**: Optional B2 settings in `.env` file
+
+### 📊 Enhanced Reporting
+
+- **File size reporting**: Backup sizes included in notifications
+- **Upload status**: B2 upload success/failure status in notifications
+- **Detailed logging**: All activities logged to centralized logs directory
+
+## Technical Implementation
+
+### Notification Function
+
+```bash
+send_notification() {
+    local title="$1"
+    local message="$2" 
+    local status="${3:-info}"
+    # Sends to webhook with tags: backup,immich,hostname
+}
+```
+
+### B2 Upload Function
+
+```bash
+upload_to_b2() {
+    local file_path="$1"
+    # Authorizes and uploads to B2 bucket
+    # Returns success/failure status
+}
+```
+
+### Configuration Updates
+
+Added to `.env` file:
+
+```bash
+# Notification settings
+WEBHOOK_URL="https://notify.peterwood.rocks/lab"
+
+# Backblaze B2 settings (optional)
+B2_APPLICATION_KEY_ID=your_key_id_here
+B2_APPLICATION_KEY=your_application_key_here  
+B2_BUCKET_NAME=your_bucket_name_here
+```
+

+## Files Added

+   - Executable file for B2 operations
+
+## Testing Results
+
+✅ **Successful test run showed:**
+
+- Environment variables loaded correctly
+- Webhook notifications sent successfully
+- Database backup created and compressed
+- Container pause/unpause functionality working
+- Error handling and cleanup working properly
+- Notifications include proper emojis and formatting
+
+## Next Steps
+
+### User Action Required
+
+1. **Configure B2 (Optional)**:
+   - Create Backblaze B2 account and bucket
+   - Generate application keys
+   - Add credentials to `.env` file
+
+2. **Test Full Backup**:
+   - Run complete backup: `./immich/backup-immich.sh`
+   - Verify notifications received
+   - Check B2 uploads (if configured)
+
+3. **Setup Automation**:
+   - Add to crontab for scheduled backups
+   - Monitor backup logs in `/home/acedanger/shell/logs/`
+
+## Benefits
+
+- **Visibility**: Real-time notifications of backup status
+- **Reliability**: Off-site backup storage with B2
+- **Consistency**: Same notification pattern as Plex backups  
+- **Monitoring**: Enhanced logging and error reporting
+- **Scalability**: Easy to extend with additional storage providers
+
+## Pattern Consistency
+
+The implementation follows the same notification and logging patterns established in the Plex backup script, ensuring consistency across the backup system.
