(repository root) which matches: - Local build setup (docker build -f docker/backup/Dockerfile .) - Dockerfile COPY commands (COPY docker/backup/backup.sh ...)

Follows the established two-step pattern used by other services: 1. Create storage directories (create-backup-storage.yml) 2. Deploy configuration files (deploy-backup-config.yml) Changes: - Add RenderBackupTemplatesStep for rendering backup.conf and backup-paths.txt - Add CreateBackupStorageStep for creating /opt/torrust/storage/backup/etc - Add DeployBackupConfigStep for deploying config files via Ansible - Add backup::release() orchestration module (checks if backup enabled) - Create two Ansible playbooks following established patterns - Update release workflow to call backup::release() between mysql and caddy - Add backup error variants: CreateBackupStorageFailed, DeployBackupConfigFailed - Add ReleaseStep::CreateBackupStorage enum variant - Fix helper function placement (before #[cfg(test)] to avoid clippy error) - Add 'isdir' to project-words.txt for Ansible stat module field - Update UserInputs domain model to include backup field Architecture alignment: - Follows DDD layer separation (domain, application, infrastructure) - Matches prometheus/grafana/caddy release step patterns - Backup skipped gracefully when user_inputs.backup() is None - Comprehensive error handling with troubleshooting guidance Test results: -

From: Jose Celano Date: Tue, 3 Feb 2026 19:15:25 +0000 Subject: [PATCH 23/45] fix: [#315] Correct SQLite database path in backup configuration - Fix incorrect SQLite database path from lib/ to lib/database/ - The tracker database is stored in lib/database/ subdirectory, not lib/ - Update backup_templates.rs to use correct path when generating backup config - Fix backup template build directory path from storage/backup/etc to backup/etc - Add comprehensive backup verification guide for E2E testing - Document actual backup file structure and naming conventions - Add backup service reference to manual E2E testing README - Update environment context to pass backup config through initialization - Improve test coverage for backup template rendering with backup config - All tests now properly configure backup via EnvironmentTestBuilder Verification: - Manual backup execution now works correctly with SQLite - Database backup file created and compressed successfully - Config backup archive contains all expected files - All linters and pre-commit checks pass --- docs/e2e-testing/manual/README.md | 11 + .../e2e-testing/manual/backup-verification.md | 386 ++++++++++++++++++

This allows Dockerfile COPY commands to use simple relative paths (backup.sh) instead of full paths from repo root (docker/backup/backup.sh). Changes: - workflows/backup-container.yaml: context: . → context: ./docker/backup - docker/backup/Dockerfile: Reverted COPY commands to simple paths Rationale: Docker COPY is always relative to build context, not Dockerfile location. By setting context to ./docker/backup, files are referenced naturally from the Dockerfile's perspective.

Adjust retention_days if disk space becomes an issue + +3. **Schedule backups during off-peak hours**: + - Backup briefly stops the tracker (~10-15 seconds) + - Schedule when user traffic is lowest + - Avoid peak usage times + +4. **Test backup restoration occasionally**: + - Verify backups are actually restorable + - Document restoration procedures + - Test with staging environment first + +5. **Keep configuration and database backups in sync**: + -
