-## ⚪ [ruvds-backup-daily-kreknin] — ежедневный backup RUVDS → kreknin (rclone SFTP), параллель `[vds-backup-rsync-kreknin]`
+## 🟢 [ruvds-backup-daily-kreknin] — daily rclone SFTP RUVDS → kreknin live (run #1 ✓ 2026-05-24 11:46:51, 20 sec, all 5 components synced)

-**Status:** ready
-**Where I stopped:** (not started — создан 2026-05-24 параллельно soak'у `[iis-migration-to-ruvds]`)
-**Next action:** см. [ruvds-backup-daily-kreknin.md](ruvds-backup-daily-kreknin.md) полный sketch. Order: (1) install rclone single-binary на RUVDS, (2) generate SSH key для kreknin auth + user добавляет pubkey в kreknin `/volume1/homes/vitya/.ssh/authorized_keys`, (3) написать `C:\ProgramData\backup\run.ps1` (snolla sync + IIS config snapshot + cert export + ntfy notification + retention prune 7 daily), (4) Register-ScheduledTask `RUVDS-Backup-Daily` SYSTEM-account, 04:30 MSK (за 30 мин до VDS backup 05:00), (5) manual smoke run + verify kreknin path + ntfy push в vds-backup topic.
+**Closed:** 2026-05-24 11:46:51 — full pipeline live, ntfy success fired.

-Pattern параллель `[vds-backup-rsync-kreknin]` 🟢 (VDS Ubuntu + rsync + cron). Differences: Win Server Core → rclone (single .exe) + Task Scheduler + SYSTEM principal. Trigger: пока soak window открыт — даже до full cutover backup нужен для rollback-evidence. **Закрывает Open question "Backup strategy для RUVDS IIS"** из `[iis-migration-to-ruvds]`.
+**Components synced (5):**
+- `sites/snolla` 8.8 GB / 44725 files (`C:\sites\snolla\`)
+- `iis-config/` (`applicationHost.config`)
+- `iis-backup-webconfiguration/` (`Backup-WebConfiguration -Name daily-<date>` export)
+- `certs/` 14 PFX (LocalMachine\My private-key certs, pass `ruvds-backup-pfx`)
+- `ssh-config/` (sshd_config + administrators_authorized_keys)
+
+**Path on kreknin:** `/volume1/NetBackup/ruvds-iis/<date>/`. Retention 7 daily snapshots (pruned by rclone purge step 4).
+
+**Schedule:** Task `RUVDS-Backup-Daily`, daily 04:30 MSK as SYSTEM, 2h timeout.
+
+**Notifications:** ntfy `vds-backup` topic (shared с VDS backup для phone-side aggregation). Title differentiator: `RUVDS backup OK/FAILED (<date>)`.
+
+**Scripts:** `scripts/ruvds-backup-daily-kreknin/` — `setup.ps1` (one-time install: SSH key + rclone + configs + ScheduledTask) + `run.ps1` (live backup logic) + README.
+
+**Findings (Decisions log):**
+- rclone SFTP без host-key validation (rclone go-sftp library не parsит ssh-keyscan format корректно — key mismatch даже на fresh keys; key-auth = sufficient для нашего threat model)
+- `Invoke-Rclone` wrapper нужен — `$ErrorActionPreference='Stop'` + rclone NOTICE на stderr = PS terminating error; wrapper switches к Continue для rclone calls
+- `Backup-WebConfiguration -Force` параметр отсутствует на этой версии IIS module — используем `Remove-WebConfigurationBackup` если exists + plain `Backup-WebConfiguration`
+
+**Open follow-ups (не блокер):**
+- PFX export pass `ruvds-backup-pfx` — temporary. TODO: pass-equivalent на Windows (gpg4win + pass-bash, или derived от machine-creds).
+- Retention prune ещё не сработал (1 snapshot today, < 7); проверится в day 8.
+
+**Atomic revert:** см. `scripts/ruvds-backup-daily-kreknin/README.md` §Atomic revert.
+
+**Closes** "Backup strategy для RUVDS IIS" Open question в `[iis-migration-to-ruvds]`.

+- rclone `--log-file` указывал на тот же путь что и `Start-Transcript` → file lock. Убрали `--log-file` (transcript captures всё необходимое).
+- rclone NOTICE на stderr + `$ErrorActionPreference = 'Stop'` = PS terminating error даже c `2>$null`. Решение: `Invoke-Rclone` wrapper-функция temporarily switches к `ErrorActionPreference = 'Continue'`.
+- ssh-keyscan'енный known_hosts не proходит rclone go-sftp library (key mismatch). Решение: убрать `known_hosts_file` из rclone.conf, полагаться на key-auth.

+# ruvds-backup-daily-kreknin — scripts
+
+Ежедневный backup RUVDS (`80.64.31.36` Win Server 2025 Core) → kreknin Synology (`195.19.90.188:/volume1/NetBackup/ruvds-iis/<date>/`) via rclone SFTP.
+
+Live since **2026-05-24**. Schedule: daily **04:30 MSK**. Task name: `RUVDS-Backup-Daily`.
+
+## Files
+
+- `setup.ps1` — one-time install: SSH key, rclone, configs, ScheduledTask.
+- `run.ps1` — backup logic (synced to `C:\ProgramData\backup\run.ps1` by setup.ps1).
+
+## Initial install (rebuilding RUVDS from scratch)
+
+```powershell
+# На RUVDS, PowerShell as Administrator
+mkdir C:\backup-scripts -Force
+# Копируем оба файла из source repo:
+Copy-Item \\tsclient\C\Users\vitya\projects\.admin\scripts\ruvds-backup-daily-kreknin\*.ps1 C:\backup-scripts\
+C:\backup-scripts\setup.ps1
+```
+
+Setup паузится после генерации SSH key — нужно добавить `kreknin-key.pub` в `/volume1/homes/vitya/.ssh/authorized_keys` на kreknin (через SSH/DSM File Station), потом Enter.
+
+## What's backed up (5 components)
+
+| Component | Source | Remote path on kreknin |
+|---|---|---|
+| snolla site content | `C:\sites\snolla\` (~8.7 GB) | `NetBackup/ruvds-iis/<date>/sites/snolla/` |
+| applicationHost.config | `C:\Windows\System32\inetsrv\config\applicationHost.config` | `NetBackup/ruvds-iis/<date>/iis-config/` |
+| IIS native config backup | `Backup-WebConfiguration -Name daily-<date>` | `NetBackup/ruvds-iis/<date>/iis-backup-webconfiguration/` |
+| LE certs (PFX export) | `Cert:\LocalMachine\My` private-key certs (14 PFX, pass `ruvds-backup-pfx`) | `NetBackup/ruvds-iis/<date>/certs/` |
+| SSH state | `C:\ProgramData\ssh\` (sshd_config + administrators_authorized_keys) | `NetBackup/ruvds-iis/<date>/ssh-config/` |
+
+Retention: **7 daily snapshots**. Older — pruned by `rclone purge` in step 4.
+
+## Notifications
+
+ntfy topic `vds-backup` (shared with VDS backup) — phone push:
+- Success: title `RUVDS backup OK (<date>)`, tag `green_circle`, priority `default`
+- Fail: title `RUVDS backup FAILED (<date>)`, tag `red_circle`, priority `high`
+
+## Decisions log
+
+- **rclone, not rsync** — Win Server Core нет cygwin/WSL, rsync.exe = пакет, security surface. rclone single .exe.
+- **SFTP без host-key validation** — rclone go-sftp library не parsит SSH known_hosts с keyscan format корректно (key mismatch error даже на fresh keyscan). Path RUVDS↔kreknin через public internet, но key auth достаточно для нашего threat model. Если threat model меняется — populate known_hosts file from `ssh-keyscan` в правильном format.
+- **`Invoke-Rclone` wrapper** — `$ErrorActionPreference = 'Stop'` + rclone NOTICE на stderr = native command terminating-error в PS. Wrapper temporarily switches к Continue для rclone calls, restores after. Без этого `2>$null` не помогает (PS видит non-empty stderr stream как error).
+- **`Backup-WebConfiguration -Force`** — параметра нет в этой версии WebAdministration module. Используем `Get-WebConfigurationBackup + Remove-WebConfigurationBackup` если exist + plain `Backup-WebConfiguration`.
+- **Cert PFX export pass = `ruvds-backup-pfx`** — temporary. TODO: pass-equivalent на Windows (gpg4win + pass-bash) или derived от machine-creds.
+- **SYSTEM principal, не user account** — Task Scheduler SYSTEM имеет full access к C:\sites\, Cert:\LocalMachine\My, %SystemRoot%\System32\inetsrv\, не требует stored-password. Pattern matches VDS root-cron decision.
+
+## Smoke run (manual)
+
+```powershell
+Start-ScheduledTask -TaskName 'RUVDS-Backup-Daily'
+# Watch:
+Get-Content C:\ProgramData\backup\logs\(Get-Date -Format yyyy-MM-dd).log -Wait
+```
+
+Verify on kreknin:
+```powershell
+ssh vitya@195.19.90.188 'du -sh /volume1/NetBackup/ruvds-iis/*/sites/snolla/'
+```
+
+## Atomic revert (uninstall)
+
+```powershell
+# On RUVDS:
+Unregister-ScheduledTask -TaskName 'RUVDS-Backup-Daily' -Confirm:$false
+Remove-Item C:\ProgramData\backup -Recurse -Force
+# Optionally: Remove-Item 'C:\Program Files\rclone' -Recurse -Force
+
+# On kreknin (via SSH):
+ssh vitya@195.19.90.188 'rm -rf /volume1/NetBackup/ruvds-iis'
+# Remove the RUVDS pubkey line from authorized_keys (one line with 'ruvds-backup' comment).

+    4. Write config.env с ntfy creds (chmod-equiv via icacls SYSTEM+Administrators).
+    5. Deploy run.ps1 (companion file в this folder).
+    6. Register ScheduledTask `RUVDS-Backup-Daily` daily @ 04:30 MSK as SYSTEM.
+
+    User action required between steps 1 и 6: add `kreknin-key.pub` to
