# 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
```
