Building an iCloud alternative for personal use is a challenging but rewarding project. Here are some key steps and considerations:

1. **Hardware**: You'll need a reliable server setup. This could be a dedicated server or a powerful NAS (Network Attached Storage) device. Ensure you have sufficient storage, processing power, and a stable internet connection.

2. **Software**:
   - **Operating System**: A Linux distribution like Ubuntu Server is a popular choice for home servers.
   - **Cloud Software**: Nextcloud is a robust, open-source solution that offers file storage, calendar, contacts, and more.
   - **Backup Solutions**: Implement regular backup solutions to prevent data loss.

3. **Security**:
   - **Firewall**: Protect your network with a firewall.
   - **Encryption**: Use encryption for data at rest and in transit.
   - **Authentication**: Implement strong authentication mechanisms, like two-factor authentication.

4. **AI Training**:
   - **Face Recognition**: Open-source libraries like OpenCV or frameworks like TensorFlow can be used for training AI models on facial recognition.
   - **Data Processing**: Ensure you have the computational resources to handle AI training, which can be resource-intensive.

5. **Maintenance**: Regularly update your software to patch security vulnerabilities and improve performance.

6. **Legal and Ethical Considerations**: Be mindful of privacy laws and ethical considerations when handling personal data.

While it's a significant undertaking, many people find it worthwhile for the control and privacy it offers. There are numerous online communities and resources that can provide guidance and support throughout the process. 

 I'm unable to upload photos,
 is it something wrong with client or relays I'm using 

 There could be several reasons why you're unable to upload photos. Here are some steps to troubleshoot the issue:

1. **Check Your Internet Connection**: Ensure you have a stable internet connection.

2. **Client Issues**:
   - **Update the Client**: Make sure you're using the latest version of the client.
   - **Restart the Client**: Sometimes, simply restarting the application can resolve issues.
   - **Check Settings**: Ensure that the client settings allow photo uploads.

3. **Relay Issues**:
   - **Check Relay Status**: Some relays might be down or experiencing issues. You can check the status of the relays you're using.
   - **Switch Relays**: Try using a different relay to see if the issue persists.

4. **File Size and Format**: Ensure that the photos you're trying to upload meet any size and format requirements set by the client or relay.

5. **Error Messages**: Look for any error messages that might provide more details about the issue.

6. **Logs**: If the client provides access to logs, check them for any error messages or warnings that could give you more insight.

If you've tried these steps and are still having issues, you might want to reach out to the support community for the client or relay you're using. They might have more specific advice or be able to identify if there's a known issue.
