We mirror its backup + architecture and patterns closely, and deliberately improve on it in three places + (progress UI, partial-file cleanup, MySQL/SQLite compression) — each called out below. + +## Problem + +The backup/restore system is fragile ("dá vários paus"). Root causes: + +1. **Monolithic code.** `src/main/services/backup.ts` is a single 1436-line file with + `buildXxxCommand()` functions side by side, mixing external-binary logic with + driver-based fallbacks scattered into `ipc/export.ts`. Hard to maintain; easy to + break (e.g. MySQL `--tables` argument ordering is fragile by construction). +2. **Runtime bugs no test catches.** Strong unit tests exist for command building + (`backup.test.ts`, ~7079 lines) but nothing validates a real backup→restore cycle, + so the worst bugs only surface at runtime: + - **Redis:** `redis-cli --rdb` produces an RDB file that `redis-cli --pipe` cannot + restore — the backup is unusable. + - **ClickHouse over SSH:** native CLI wants TCP 9000, SSH maps HTTP 8123 — fails. + - **ClickHouse full dump:** exports DDL only, silent data loss. + - **MongoDB:** >1 collection silently becomes a full-database dump. + - **Logs:** truncated to last 512KB, losing the start of long errors. +3. **Command-centric UI.** The execute step (`StepExecute.vue`) leads with a raw command + preview and a raw stdout/stderr log dump — noisy and intimidating. + +## Goals + +- Refactor `backup.ts` into a maintainable, testable structure (one file per dialect), + mirroring Beekeeper's `backup-clients/` + `restore-clients/` layout. +- Fix the five runtime bugs above as part of the refactor. +- Replace the command-dump execute screen with a clean progress screen. +- Add backup→restore round-trip integration tests so runtime bugs can't silently return. + +## Non-goals + +- No redesign of the entity-selection step (beyond mirroring Beekeeper's component split). +- The configure step changes only to render per-dialect options dynamically from each + client's `settingsSections` — no broader wizard rework. +- No new export formats for the user-facing grid export (CSV/JSON) — that path stays. + +## Decisions + +1. **Architecture:** abstract `BaseCommandClient` + one client per dialect under + `backup-clients/` and `restore-clients/`, wired by a `commandClientsFor(dialect)` + factory — exactly Beekeeper's structure. Adapted to our stack (Vue 3 + Pinia instead of + Vuex; our IPC layer) and **extended** to cover Redis and ClickHouse, which Beekeeper + leaves as `NotImplemented`. +2. **Backup method rule:** + - **General case → official tool always** (`pg_dump`, `mysqldump`, `mongodump`, + `sqlite3`, `duckdb`, `sqlcmd`). If the tool is **not installed**, **do not back up** — + show a clear error telling the user to install it. **No automatic driver fallback in + the general case.** + - **SSH is NOT a reason to use the driver.** For PostgreSQL, MySQL/MariaDB and MongoDB, + a connection over SSH already forwards the DB's TCP port to `127.0.0.1:localPort` + (`ssh-tunnel.ts` + `resolveHostPort()` in `backup.ts:234`). The official tool runs + **through the tunnel** against `127.0.0.1:localPort` — the fast, optimal path and the + common production case. Already works today; keep it. (Beekeeper does the same: + `tunnel.ts` forwards the port, clients inject `--host=localHost --port=localPort`.) + - **Driver path used ONLY where the official tool cannot viably work:** + - **Redis** — always. No official remote logical-dump tool exists: `redis-cli --rdb` + is a binary snapshot only restorable by placing it on the server's disk and + restarting; `--pipe` speaks RESP, not RDB. Driver uses `SCAN` + `DUMP`/`RESTORE` + + `PTTL`, which round-trips over any connection (incl. SSH). + - **ClickHouse** — always. The official CLI needs native TCP 9000 (not tunneled over + SSH, which forwards HTTP 8123) and has no good logical-dump tool; `.dump` yields DDL + only. The driver runs over HTTP and works everywhere, incl. through SSH tunnels. + - **Note:** Beekeeper does **not** implement Redis or ClickHouse backup at all (both + return `NotImplementedBackupClient`). Our driver clients for these are original work. +3. **Restore detection (no manifest):** mirrors Beekeeper — there is **no metadata/manifest + file**. The restore client is chosen by the **active connection's dialect** + (`commandClientsFor(connectionType)`); the user picks the backup file (and, for + PostgreSQL, whether it's a file or a directory via the `isDir` setting). Format follows + from the dialect + the user's selection. This drops the manifest entirely from the + earlier draft. +4. **UI — progress screen (we diverge from Beekeeper here, intentionally):** Beekeeper's + `BackupProgress.vue` shows the raw command log + start/end timestamps and **no progress + bar**. We instead show a **progress screen** (the user's explicit request): spinner + + elapsed time + growing output-file size for the official-tool path, a real + percentage/ETA bar for the driver path, and the raw command + log moved behind a + collapsed "Detalhes técnicos" disclosure. IPC handler signatures stay stable. +5. **Partial-file cleanup (we improve on Beekeeper):** on cancel or error, delete the + partial backup artifact (adopt the `deleteOnAbort` pattern Beekeeper already uses for + its native export, but apply it to backups too). Beekeeper leaves partial files on disk; + we don't. +6. **Compression (we extend Beekeeper):** native compression where the tool supports it + (PostgreSQL `--compress`); **optional gzip for MySQL/SQLite** (a checkbox — + `mysqldump | gzip`). No outer-zip double compression. Beekeeper compresses only + PostgreSQL natively and leaves MySQL/SQLite uncompressed. +7. **Testing:** per-client unit tests + Docker round-trip integration tests. + +## Architecture + +New tree under `src/main/services/backup/`, mirroring Beekeeper's `lib/db` layout +(file and class names match theirs 1:1 except the added Redis/ClickHouse clients): + +``` +src/main/services/backup/ +├── index.ts # Public API — same signatures ipc/backup.ts already imports +├── CommandClient.ts # commandClientsFor(dialect) → { backup, restore } factory +├── BaseCommandClient.ts # Abstract base: common flow + shared setting sections +├── models.ts # Command, CommandSettingSection/Control, BackupFormat, etc. +├── models/ +│ └── BackupConfig.ts # BackupConfig class (mirrors Beekeeper) +├── orchestrator.ts # Runs the chosen client; progress, cancel, partial cleanup +├── BinaryFinder.ts # Binary detection (extracted from current findBinary) +├── compression.ts # gzip helpers (only where used; no double compression) +├── types.ts # BackupMethod, ProgressEvent, etc. +├── backup-clients/ +│ ├── index.ts # Re-exports all backup clients +│ ├── postgresql.ts # PostgresBackupClient +│ ├── mysql.ts # MySqlBackupClient (mysqldump / mariadb-dump) +│ ├── sqlite.ts # SqliteBackupClient +│ ├── duckdb.ts # DuckdbBackupClient +│ ├── sqlserver.ts # SqlServerBackupClient +│ ├── mongodb.ts # MongoBackupClient (mongodump) +│ ├── clickhouse.ts # ClickHouseBackupClient (driver — our extension) +│ ├── redis.ts # RedisBackupClient (driver — our extension) +│ └── NotImplementedBackupClient.ts +└── restore-clients/ + ├── index.ts # Re-exports all restore clients + ├── postgresql.ts # PostgresRestoreClient (pg_restore / psql, mode='restore') + ├── mysql.ts + ├── sqlite.ts + ├── duckdb.ts + ├── sqlserver.ts + ├── mongodb.ts + ├── clickhouse.ts + ├── redis.ts + └── NotImplementedRestoreClient.ts +``` + +Native serializers (Redis JSON+TTL via `DUMP`/`RESTORE`, Mongo Extended-JSON) live in +`backup-clients/`/`restore-clients/` for Redis/ClickHouse/Mongo and are migrated out of +`ipc/export.ts:660+` (see "export.ts consolidation"). + +Mirrored tests: +- `src/tests/unit/main/backup/` — per-client unit tests. +- `src/tests/integration/backup/` — round-trip tests. + +### Responsibilities + +- **`index.ts`** — keeps exactly the functions `src/main/ipc/backup.ts` imports today + (`executeBackup`, `executeRestore`, `detectBinary`, `getEntities`, `buildCommand`, + `cancel`, binary-path getters/setters).
