--- title: Overview --- # Operations Operator-facing runbooks for maintaining a running Themelio instance: backup and restore procedures, migration playbooks, and other day-2 tasks. - [Backup GitLab repositories](./backup-gitlab-repos) — mirror every Git repository (refs, branches, tags, and Git LFS objects) from a source GitLab instance to a target GitLab instance, preserving the group hierarchy. - [Waldur GitLab Sync](./waldur-gitlab-sync) — create and manage GitLab groups, members, and metadata in response to Waldur project lifecycle events. - [Local Stack Known Issues](./local-known-issues) — issues and lessons for the full local stack (`make local-up`), covering both WSL2/VHD and native Linux/loop-device hosts. - [ADR-0025 Validation](./adr-0025-validation) — execute and record the scoped Istio host, workload-identity, ambient mTLS, observability, and affected application regression validations one gate at a time.
