what is n8n-backup-manager fr?

n8n Backup Manager is an automatic backup and restore tool for n8n, an open source workflow automation platform. If you self host n8n, the workflows and settings you build live in a local database, and this tool exists to make sure that data is regularly backed up so you do not lose your work if something goes wrong. It runs as a separate service alongside your n8n installation and provides a web based dashboard where you can see backup history, trigger a backup manually, restore from a previous backup, and configure automatic schedules by interval or cron expression. It supports both PostgreSQL and SQLite databases, and can compress backups with Gzip and encrypt them with AES-256, a strong encryption standard. A retention policy can automatically delete old backups after a set point so storage does not fill up, and individual backups can be protected from that auto deletion. Backups can be stored locally or automatically uploaded to cloud storage: S3 compatible services such as AWS or DigitalOcean Spaces, Google Drive, or Microsoft OneDrive. You can set up Telegram notifications so you get an alert whenever a backup succeeds or fails, and the dashboard shows a chart of backup size over time. There is also a backup integrity check that verifies an archive is healthy, though that specific feature only works on Linux and is hidden automatically on Windows and macOS. You would use this if you run your own instance of n8n and want your automation workflows backed up on a schedule without having to remember to do it manually. It runs via Docker and is recommended for Linux servers in production, while Windows and macOS are supported for local development without Docker.
