aws_session_token = "your_session_token"

s3 = boto3.client("s3", aws_access_key_id=aws_access_key_id, aws_secret_access_key=aws_secret_access_key, aws_session_token=aws_session_token)

# Upload a file to your S3 bucket
def upload_to_s3(file_path, bucket, s3_key):
    with open(file_path, "rb") as f:
        s3.upload_fileobj(f, bucket, s3_key)
    print(f"Uploaded {file_path} to s3://{bucket}/{s3_key}")

# Backup your chat logs
chat_logs_file_path = "chat_logs.json"
s3_bucket = "your_s3_bucket"
s3_key = "backups/chat_logs.json"

upload_to_s3(chat_logs_file_path, s3_bucket, s3_key)

This code example shows how to upload a file (e.g., chat logs) to an Amazon S3 bucket using the boto3 library. You can schedule regular backups of your data and application configurations to minimize the risk of data loss.

For disaster recovery, consider using cloud-based services like AWS, Google Cloud, or Azure that offer built-in redundancy, automated backups, and recovery tools.
