Backup and Updates

All persistent Docker data lives in ./data.

Backup

To back up a Docker install, stop the container and copy the data directory:

docker compose down
cp -R data data.backup
docker compose up -d

For local installs, the default database and image cache are under:

data/db/ytzero.db
data/imgcache

Updates

Update a Docker install that uses the published GHCR image:

docker compose pull
docker compose up -d

Update a Docker install that builds locally after pulling new code:

docker compose -f docker-compose.dev.yml up --build -d

Schema changes are applied automatically on startup, so updates do not require manual migration steps. Back up ./data first if you want a safety net.
