Back up and restore plain directories, alongside the database sources.

Files source and Archive (P0)
- `files` type: absolute path (not /), options.exclude and
  options.one_file_system; walk + tar.gz with symlinks kept as links,
  special files skipped, unreadable entries fail the run.
- Mirror restore: archive validated first, then everything not excluded
  is wiped (mount points and special files kept) and the archive is
  extracted, retrying without metadata on filesystems refusing chown/chmod.
- Windows-safe platform helpers; helm extraVolumes/extraVolumeMounts.

Universal rclone mapper (P1)
- rclone_target(storage) for s3, blob, gcs, drive, rclone and sftp; sftp
  goes through it; rclone obscure reads the password from stdin.

Snapshots, restic (P2)
- restic in the image; repository per source and channel, password
  derived from the master key (HKDF); stable host, bs:<row> tags,
  translated excludes; exit 3 fails and forgets the snapshot.
- Mirror restore with `restic restore --delete`; restore payload carries
  the encrypted channel; snapshot ids must be full ids.
- Engine in the ping and in scheduled task metadata.

One locked method per source (spec A)
- databases.json declares options.method (archive, snapshot, sync),
  reported in the ping for local sources only.
- Sync: rclone sync per channel onto <folder>/sync/<id>/current, refuses
  an empty source, reports transferred/deleted counters.

Local channel (spec B)
- Snapshots and Sync reach the dashboard's local storage through its
  append-only restic REST server and its WebDAV server.

Security
- Strict rclone config validation: one section, no duplicate keys, no
  command, credential or host-file keys, no quoted values, valid backend
  type, blocked backends.
- Scheduled task metadata (decrypted storages) is no longer logged.

📝 Walkthrough

The pull request adds file-backed databases with archive, Restic snapshot, and rclone sync engines. It adds storage-target generation, restore and status wiring, agent request authentication, deployment mounts, Restic tooling, seed scripts, and extensive integration tests.

Changes: File database support

Layer / File(s) Summary
File operations and engines
src/domain/files/*
Adds archive backup and restore, Restic snapshot and restore, rclone synchronization, exclusions, statistics, locking, and platform helpers.
Configuration and service wiring
src/services/config.rs, src/services/backup/*, src/services/restore/*, src/services/status.rs
Adds the files database type, archive/snapshot/sync methods, engine dispatch, restore handling, status payload fields, and encrypted restore-storage resolution.
Storage targets and validation
src/services/storage/providers/*
Adds Restic and local-storage credentials, provider-specific rclone targets, stricter rclone validation, password handling through stdin, and SFTP target reuse.
Validation coverage
src/tests/domain/files/*, src/tests/services/*, src/tests/storage/*
Adds unit, integration, fixture-driven, and container-backed tests for file operations, engines, configuration, storage targets, and API payloads.

Agent authentication

Layer / File(s) Summary
Key derivation and request signing
src/services/api/client.rs, src/utils/edge_key.rs, src/tests/services/api_client_tests.rs
ApiClient derives an agent key and signs requests with the method, API-prefixed path, timestamp, and body hash. Signed requests include timestamp and signature headers.
Authentication configuration
src/core/context.rs, docker-compose.yml
Context configures ApiClient with the edge key’s agent ID and master key. The compose configuration uses a different encoded edge key.

Deployment and test data

Layer / File(s) Summary
Runtime and file-source setup
docker/Dockerfile, helm/*, databases.json, justfile, scripts/files/seed-1gb.sh
Adds Restic to container images, optional mounted file volumes to Helm deployments, sample file databases, and file-data seeding commands.

Merge Risk: 🟡 Moderate · up to d81b0

File sync backups can delete an existing replica if the source directory disappears or empties after the initial check. Sync backups can also ignore the encryption setting and write unencrypted copies. The development compose file still commits a signing key that can forge agent requests. Resolve these issues or explicitly accept them before merging.

🟠 Major · Make the empty-source guard safe against unmount races. · rclone.rs:19-22

src/domain/files/sync/rclone.rs:19-22
🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Make the empty-source guard safe against unmount races.

read_dir(&root).next() checks the source only before rclone starts. If the mounted volume is unmounted and its mount point is empty, or the source becomes empty before rclone walks it, rclone sync can delete the existing replica. This command also enables --delete-excluded. Rclone documents that sync makes the destination identical and that --delete-excluded deletes excluded destination files. (tip.rclone.org)

The error message promises that an unmounted volume cannot wipe the replica, but this race violates that guarantee. Use an authoritative mount, sentinel, or device-identity check, and fail closed before allowing destructive synchronization. Add a regression test with an existing replica and an empty source.
