# Backup via comando nativo do Gitea:
docker compose exec gitea gitea admin user list
docker compose exec gitea gitea dump -c /data/gitea/conf/app.ini -w /tmp/backup

# Copiar o backup para fora do container:
docker compose cp gitea:/tmp/backup.zip /var/backups/gitea-$(date +%Y%m%d).zip

# Backup manual do banco + volumes:
DATE=$(date +%Y%m%d_%H%M)
docker compose exec -T postgres pg_dump -U gitea gitea \

# Manutenção do banco de dados Git (compactar repos):
docker compose exec gitea gitea admin git fsck-repos --all
