Scalingo provides automated daily snapshots for managed PostgreSQL databases, which facilitate rapid restoration by creating a new database instance from a specific point in time. This approach minimizes downtime during recovery but requires updating application environment variables to point to the new host. Alternatively, utilizing manual pg_dump exports p
Recovery Goal and Current Constraint The objective is to recover a production Droplet to a known-good state after a failed system upgrade using a previously captured snapshot. Current documented behavior requires provisioning an entirely new Droplet from the snapshot image rather than performing an in-place overwrite of the existing disk. Operational Implica
Restore path and the version boundary Forgejo's documented recovery workflow is manual: import the SQL dump, unpack the data directory and repositories, restore app.ini, fix ownership. The open decision is which Forgejo binary to run against the restored database. On first startup the server migrates the schema to the binary's version, and downgrades are uns
Apache Airflow ships airflow db backup and airflow db restore to export and reimport the metadata database (PostgreSQL, MySQL, or SQLite) for disaster recovery. The restore command finishes without error, but there is no documented validation step that compares the restored database against the backup file itself — no row-count or checksum comparison is buil
Failed migration leaves the database in an intermediate state When supabase db push fails partway through a migration, the CLI does not roll back automatically. The documented recovery path is supabase migration repair , which marks a migration as applied or reverted in the schema_migrations table without re-running the SQL, or supabase db reset , which dest
Atomic Upgrade Failures Talos OS utilizes the talosctl upgrade command to atomically replace the node's OS image. Because the upgrade process does not support pausing or resuming mid-operation, a failure during the image replacement—such as a network interruption or image corruption—can leave a node in an inconsistent state. Recovery Constraints While the sy
Context An on-premises Azure DevOps Server upgrade fails after the Configuration Tool has applied database schema migrations but before all application-tier services start successfully. The instance is left in a partially upgraded state with no automatic rollback mechanism. Constraints and uncertainty Pre-upgrade backups of SQL databases, file shares, and co
Database and Shared Home Consistency Bitbucket Data Center relies on the synchronization between the database and the shared home directory for system integrity. During a recovery process following a failed upgrade, the database must be restored to a state that matches the specific snapshot of the shared home directory. When an upgrade modifies the database
Assume a Kubernetes 1.29+ cluster with a CSI-capable storage driver and Velero 1.13+ handling backup and restore. A restore can complete cleanly while revealing little about data correctness: Velero recreates API objects from its backup, an etcd snapshot reinstates the API server's stored state, but persistent volumes return only through volume snapshots or
