[Fix] Backups: one failing backup no longer aborts the whole scheduled run

[RichardAnderson]

Guards each backup inside backups:run so a single failure is logged and skipped rather than killing the command and silently skipping every later due backup, and adds a migration that clears pre-existing orphaned rows and constrains backups.server_id and backup_files.backup_id with cascading foreign keys so the condition cannot recur.

The delete in the migration

The migration removes backups rows whose server_id matches no row in servers, then backup_files rows whose backup_id matches no row in backups. These are leftovers from before #1198, when deleting a server did not delete its backups and no foreign key existed to stop it — exactly the rows that produced Attempt to read property "project_id" on null and killed the nightly backups:run. The delete is not optional housekeeping: a foreign key cannot be added to a table that already violates it, so without it the migration fails outright on MySQL (ERROR 1452) and Postgres, breaking the upgrade. The second statement sweeps all dangling backup_files, not only those under the orphaned backups, because any dangling row blocks the backup_files foreign key regardless of how it got there.

It is safe for four reasons. It uses the query builder (DB::table(...)->delete()) rather than Eloquent, so no model events fire and Backup::deleting — which walks and deletes files — never runs; this was verified empirically by running up() under a wildcard event listener with Bus::fake() and Queue::fake(), giving zero Eloquent events, zero dispatched jobs and zero queue pushes. It is targeted rather than a truncate: both statements use whereNotExists, and a legitimate server → backup → backup_file chain was confirmed to survive intact. The rows it removes are unusable by definition — their server no longer exists, the schedule can never run again, and Vito has no route to the archives they reference. And it touches database rows only; the remote archives on S3/Dropbox/FTP/local are left untouched, which is both intended and enforced, since tests/Arch/MigrationsTest.php forbids SSH::, Http::, dispatch( and App\Jobs inside migrations.

Note that this half is not reversible: down() drops both foreign keys and restores the original column type, but deleted rows cannot be recovered from within the migration.

📝 Walkthrough

Walkthrough

The backup command continues after individual failures, logs failure context, and reports started and failed totals. A migration removes orphaned records, widens backup_files.backup_id, and adds cascading foreign keys with test coverage.

Changes

Backup reliability and referential integrity

Layer / File(s)	Summary
Backup execution failure handling app/Console/Commands/RunBackupCommand.php, tests/Unit/Commands/RunBackupCommandTest.php	RunBackupCommand catches backup exceptions, logs backup and server identifiers, continues processing, and reports started and failed totals. Tests cover failure continuation and updated command output.
Backup relationship cleanup database/migrations/...delete_orphaned_backups_and_add_foreign_keys.php, tests/Feature/BackupTest.php	The migration deletes orphaned records, widens backup_files.backup_id, and adds cascading foreign keys. Feature tests cover orphan deletion and server deletion cascades.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to a5557

The scheduled backup command now skips an individual failure instead of aborting later work, but a failure after backup state is persisted can still leave a backup permanently marked as creating without a queued job. This is a bounded correctness risk requiring explicit owner awareness or follow-up.

broadcasting or dispatch setup rolls back or marks the created file as failed,
preventing a persisted CREATING file without work to complete it.

method within a single DB::transaction() callback, preserving their existing
order and queries. Keep all schema changes outside this transaction.
