🔔 Important Notice (2026-08-16): This project has been renamed

1️⃣ Repository renamed

	Old	New (current)
GitHub repo	feiyang-dev/deepseekharnessdesktop-vault	feiyang-dev/dsh-vault
Local remote	https://github.com/feiyang-dev/deepseekharnessdesktop-vault.git	https://github.com/feiyang-dev/dsh-vault.git

The old URL redirects (301) to the new one automatically. All stars / forks / issues / releases are preserved.
If you already cloned the repo locally, just update the remote:

git remote set-url origin https://github.com/feiyang-dev/dsh-vault.git

2️⃣ npm package renamed

	Old package	New package (current)
npm package	@feiyang666/deepseekharnessdesktop-vault	@feiyang666/dsh-vault

• For install / upgrade, use the new package name: dsh plugin --profile web add @feiyang666/dsh-vault
• The old package @feiyang666/deepseekharnessdesktop-vault remains published for a while, but it is no longer maintained and will not receive updates — please migrate soon.
• The desktop client (DeepSeek Harness Desktop) supports both package names and will auto-detect and upgrade installs made with the old name.

---

Overview

When the DeepSeek Harness desktop client detects a plugin load failure, it may force-clear the local ~/.dsh data (chat history, workspace data, settings, credentials, plugin configs) and restore factory defaults. dsh-vault continuously backs up all critical data to a safe location outside ~/.dsh, so your data can be fully recovered even after a wipe.

npm package: @feiyang666/dsh-vault (same series as the @feiyang666/dsh-usage-plugin usage plugin).

Features

Capability	Description
Settings page "Backup Manager"	Adds a "Backup Manager" page to the Web settings: view backup status and history, back up now, one-click restore by scope (All / Chat history only / Workspace settings only), delete backups (with confirmation)
Automatic backup	First backup 6s after startup + debounced backup after session writes/settings changes (2 min) + scheduled backup every 15 min
Backup contents	sessions/ (chat history, zstd binary full copy), storages/ (workspace data), settings.yaml, .credentials.yaml, .anonymous-user-id, profiles/ configs (excluding reinstallable node_modules)
Backup location	~/.dsh-backups/<timestamp>/ — outside ~/.dsh, untouched by data wipes
Wipe detection	On startup, compares backup vs current session count; red alert when data is suspected wiped
One-click restore	Settings page or the backup_vault tool restores by scope (All / chat history only / workspace settings only)
Restore script	Generates restore-latest.ps1; after quitting the desktop app, right-click to run and restore offline
Delete backups	Delete a specific backup by name from the settings page (with confirmation)

Recommended Installation

Either method works and is equivalent. We recommend the desktop app — fully graphical, no command line needed.

Option 1 (recommended): One-click via the desktop app

Install DeepSeek Harness Desktop, open it, then go to "Install Plugins" → Recommended → Data Vault → Install and click "Restart Service Now" to activate.

Option 2: Command line

# Prerequisite: install dsh (npm install -g @deepseek-ai/dsh)
dsh plugin --profile web add @feiyang666/dsh-vault

This plugin is a standard Cordis bundle plugin installed via npm and mounted into a dsh profile:

# 1. Install into the profile (equivalent to the official bundle mechanism)
npm install --prefix "$HOME/.dsh/profiles/web" @feiyang666/dsh-vault

# 2. Register the bundle in the profile's package.json (the dsh.vault row mounts automatically via cordis.patch.yml)
#    Or use your desktop app's plugin manager

Or manually edit ~/.dsh/profiles/web/package.json and add "@feiyang666/dsh-vault" to dsh.profile.bundles.

Usage 1: Settings page "Backup Manager" (Web)

After installing and restarting, open Settings → "Backup Manager":

• Top shows backup directory, last backup time, backup count, and data-integrity status
• "Back Up Now" button triggers a manual backup
• The "Backup History" list offers "Restore" (scope: All / chat history only / workspace settings only) and "Delete" (with confirmation) per item

Usage 2: backup_vault tool (TUI / Web universal)

The plugin registers the backup_vault model tool — just tell the assistant "back me up / check backup status / restore chat history from the latest backup / delete that old backup":

• action: status — backup directory, last backup, backup list, whether a wipe was detected
• action: backup — back up now
• action: list — list all backups
• action: restore (name + scope: all/sessions/data) — restore
• action: delete (name) — delete a backup
• action: make_script — generate a one-click restore script

Manual restore (after quitting the desktop app)

1. Find the backup directory ~/.dsh-backups/
2. If restore-latest.ps1 was generated, quit the desktop app and right-click → "Run with PowerShell"
3. Or manually copy the contents of backup-<timestamp>/ back into ~/.dsh/

Safety notes

• Backups include .credentials.yaml (API keys) — keep the backup directory safe (you may copy it to an encrypted disk / cloud drive).
• Restore overwrites current data — confirm the backup time point first.
• Chat-history files may be locked while DSH is running; it's best to quit the desktop app before restoring chat history.
