VaultSail

Sync notes and attachments through Baidu Netdisk with version preservation and password-encrypted device pairing.

中文使用说明 · 电脑与 iPad 配对

Features

• Start bidirectional sync with one click, or preview upload, download and sync changes first.
• Compare files against a verified baseline. Concurrent edits preserve every valid version and create visible conflict copies.
• Verify transferred content with SHA-256. Recover unfinished operations and restore local recovery copies.
• Export a password-encrypted code or file containing your application credentials and authorization. Account-only export and import are the default: each vault chooses its own cloud destination. Sharing an existing remote vault requires an explicit choice at both ends.
• See scan, transfer and verification progress, elapsed time, last completion and remote version locations.
• Keep deletion propagation off by default. Exclude Obsidian configuration, credentials, internal state and recovery folders from note sync.

Baidu Netdisk is the current provider. Transfers are manual, with a 20 MiB per-file limit and concurrency of one. Pairing configuration is encrypted; note contents stored in the cloud are not end-to-end encrypted. Automatic text merging and continuous mobile background sync are not provided.

Install

Requires Obsidian 1.11.4 or newer. The community listing is restored, and 0.1.16 completed the automated review with no blocking errors on October 15, 2026. Its installation link is enabled; the in-app search catalog still needs to propagate the entry. Automated review does not replace real-device validation.

For direct GitHub installation on iPad, install and enable BRAT through Obsidian's community plugins, then add gongteng0215/obsidian-vaultsail and select version 0.1.17. Enable VaultSail in an empty test vault before importing an encrypted pairing code.

For manual installation, download the ZIP or the three individual files from the 0.1.17 release. Place main.js, manifest.json and styles.css in plugins/vaultsail/ under the current vault's configuration directory, then enable VaultSail. The default directory is .obsidian; custom configuration directories are supported.

Connect your first device

1. Obtain your own AppKey and SecretKey from an approved Baidu application. A Baidu login account alone does not grant file API access.
2. Save the credentials in the connection tab and set the application's actually authorized /apps/application-name directory. The default /apps/VaultSail does not imply that access is already approved.
3. Connect through Baidu's official authorization page.
4. Create or bind a remote vault and verify file transfer permissions.
5. Start sync, or preview the changes first.

The remote vault stores vault.json, immutable content under blobs, and version operations under ops. Downloads reconstruct normal note paths. VaultSail does not mirror arbitrary existing files from elsewhere in your drive.

Pair another device

Export an account connection on the connected computer using a password of at least ten characters. Install version 0.1.17 or newer on the target device, import the code or encrypted file, and enter that password. Account and small file transfer checks run automatically, without repeating browser login. The current vault then creates or selects its own remote vault. To sync the same vault across devices, explicitly include its destination when exporting and explicitly bind it when importing. Old codes may still contain a destination; 0.1.17 ignores it unless you opt in. Codes can be imported for 24 hours. Device identity, baselines and task queues remain independent.

Revoked authorization or an invalid refresh token cannot be restored by encryption. Re-export from a connected device or authorize again when required. Legacy non-secret JSON configuration still requires a separate login. See the pairing guide.

Accounts, network and privacy

A Baidu account, an approved application and network access are required. VaultSail connects directly to Baidu OAuth (openapi.baidu.com), file APIs (pan.baidu.com, d.pcs.baidu.com) and official HTTPS download hosts under baidu.com/baidupcs.com to authorize, list, upload and download files. Application and authorization management pages open after a user action.

There is no developer-hosted authorization or sync server. Credentials are stored through Obsidian SecretStorage; plugin settings contain references. The plugin has no ads, telemetry, self-updater or file access outside the vault. It enumerates vault file paths to plan sync and writes only the requested note transfers, recovery copies and internal state. Its clipboard use writes a pairing code or storage path only after you choose to copy; it does not read clipboard contents. Diagnostics exclude credentials, filenames and note contents.

Anyone holding both a pairing code and its password can reuse its authorization. Share them only with your own devices, never in issue reports.

Verification and development

92 automated tests cover authorization, encrypted pairing, file APIs, pagination, concurrent changes, recovery, path safety and configuration privacy. Real iPad import, device storage/Web Crypto, large real-world transfers and long-term shared-token refresh remain unverified by the developer. Simulated checks are not real-device certification. See implementation status and performance measurements.

Use Node.js 22+, then run npm ci, npm test, npm run build and pwsh ./scripts/package-release.ps1. The installation ZIP contains only the three plugin files, never tests, user settings, credentials or notes.
