Add SSH credentials as first-class Django data so backup keys can be
uploaded through the control panel instead of mounted into containers.
Credentials can be selected globally or overridden per host. At runtime
the selected key is materialized inside the container with restrictive
file permissions and injected into the rsync SSH command via IdentityFile.
Known hosts entries are handled the same way when configured.
Add control panel views for creating and listing SSH keys, expose the
fields in config forms and admin, document the workflow, and cover global
and host credential selection with tests.
Add linked admin summaries for hosts, snapshots, and backup runs so the SQL-first
backup state is easier to inspect from the Django admin. Hosts now link to their
filtered snapshot and run lists, backup runs link back to their snapshot, and
snapshots show base/run relationships without requiring filesystem inspection.
Cover the new admin display helpers with focused tests.
Add a nullable SnapshotRecord foreign key to BackupRun and populate it
when run_pobsync_backup records a completed or failed snapshot. Keep the
existing snapshot_path for audit compatibility while making run-to-snapshot
navigation explicit in the database and admin.
Add a Django-native snapshot discovery service and management command
that scans backup directories, reads snapshot metadata, and idempotently
upserts SnapshotRecord rows. Expose it through the pobsync command
wrapper, update admin/docs, and cover discovery behavior with tests.
Add explicit Django model fields for global and host backup settings,
including SSH, rsync, source, excludes, and retention configuration.
Populate them from legacy JSON during migration, make the config
repository prefer structured fields, and update import/admin/tests around
the SQL-first configuration model.
Introduce a ConfigSource interface so scheduled backups no longer need
to load host configuration directly from runtime YAML. Add a Django-backed
config source for SQL-driven backup runs, keep file-based config as the
CLI default, and make scheduled prune execution actually apply retention
after successful runs.
Add a Django admin-backed management layer for pobsync configs, runs,
snapshots, and schedules. Keep the existing CLI engine as the execution
source of truth, add import/run management commands, and provide SQLite
default plus optional MariaDB Docker Compose support.
