# Upgrades and backups

Keep an instance current, and its data safe.

This guide is a placeholder. The full version is on its way.

## Upgrades

Upgrade with the Compose project name the instance started with. A different name starts a new, empty instance.

## Backups

Back up PostgreSQL, stored files, ClickHouse, Redis and the configuration volume together, so they restore to the same moment.

Never regenerate an instance's secrets to fix a start-up problem: what they encrypt would become unreadable.
