# Backups and recovery

> Protect presentations, uploads, settings, and databases.

## What to back up

* The complete `/app_data` volume
* The external database when `DATABASE_URL` is configured
* Deployment configuration without exposing secrets in an unsafe location
* The exact Presenton image tag or digest used by the backup

`/app_data` may contain presentations, uploads, generated assets, exports, templates, settings, authentication state, the default SQLite database, and local presentation memory.

## Recovery procedure

1. Stop writes to the affected deployment.
2. Create a safety copy of the current data before restoring anything.
3. Restore `/app_data` and any external database from matching backups.
4. Start the same Presenton version used when the backup was created.
5. Verify sign-in, presentations, uploads, providers, editing, export, API, and MCP as applicable.
6. Upgrade only after the restored deployment is healthy.

<Warning>
  A backup is not complete until it has been restored successfully in a separate test environment.
