This n8n workflow automates the process of backing up and updating GitHub files and workflows at scheduled intervals, ensuring data integrity and version control. It begins by retrieving existing files from a GitHub repository, transforms the data for consistency, and creates or updates files with the latest information. Additionally, it interacts with a local n8n instance to manage workflow data, fetching current workflows, downloading raw content from GitHub, and merging information for seamless updates. The workflow is triggered daily at 23:59, making it ideal for maintaining up-to-date backups, synchronizing workflows, and managing version history automatically.
