Sync Vault 2.0 is not a routine update. It rewrote the core sync engine of the Obsidian plugin — upgrading from file-level timestamp comparison to global state management based on Yjs + IndexedDB.
In plain terms: your vault no longer relies on “whoever saved last wins.” Every change is now precisely tracked, auditable, and recoverable.
What’s New in 2.0: From Files to State
The Achilles’ heel of traditional sync plugins is the clock. Your Mac might be 3 seconds ahead of the cloud, your phone 10 seconds behind. When two devices edit the same file simultaneously, timestamp-based decisions produce incorrect overwrites.
Sync Vault 2.0 solves this with the GlobalStateManager. It uses Yjs’ CRDT algorithm with IndexedDB local persistence to record a metadata snapshot after every successful sync — creating a “baseline.” All subsequent sync decisions only compute incremental changes since the last baseline.
The result:
- Sync decisions drop from full comparison to incremental delta — only real changes are processed
- Clock domain isolation eliminates sync loops caused by time inconsistencies
- Conflicts are auto-merged, deletions are traceable and recoverable
Your AI Can Now Read Your Cloud Knowledge Base
Sync Vault 2.0 ships with a built-in MCP Server (Model Context Protocol) — the single biggest differentiator from competing plugins.
Claude, ChatGPT, Cursor, and any MCP-compatible AI assistant can directly read, search, and analyze files stored in your Baidu Drive, Alibaba Cloud Drive, Quark Drive, and more. Not a handful of context files — full access to your cloud file system.
Combined with the CLI, you can orchestrate automated workflows: scheduled indexing, semantic search, AI summary generation. Your LLM isn’t limited to “a few thousand tokens of conversation” — it understands your entire knowledge base.
Cloud Is the Source of Truth, Local Is the Workspace
This is Sync Vault’s architectural principle, executed more thoroughly in 2.0.
1+N Architecture:
- 1 = Cloud Center: Public cloud storage as the single persistent layer
- N = Live Nodes: Your Mac, Windows laptop, phone — all hot-data nodes
Each device doesn’t need to store full files locally. VFS (Virtual File System) keeps only KB-sized .osvc stubs on disk, preserving the native directory structure and icons. Click a stub and content is silently hydrated on demand.
Your phone can hold a terabyte-scale attachment library. That’s not an exaggeration.
2.0 Performance Improvements
- Alibaba Cloud Drive instant upload (秒传)
- Significant small-file upload optimizations for Baidu Drive & Alibaba Cloud Drive
- Video annotation index and file snapshot performance optimizations
- P2P real-time sync (WebRTC) with baseline-based incremental sync
Broad Cloud Compatibility
Baidu Drive, Alibaba Cloud Drive, Quark Drive, 115 Drive, OneDrive, WebDAV, Tencent Cloud COS — the most comprehensive Cloud Provider adaptation layer in the market, covering virtually all major cloud storage services in China.
All transfers are protected with AES-GCM end-to-end encryption.
FAQ
What’s the difference between Sync Vault 2.0 and 1.x?
1.x relied on file timestamps for sync decisions, which caused loops in multi-device scenarios. 2.0 introduces Yjs CRDT + IndexedDB state management for incremental sync, automatic conflict resolution, and recoverable deletion.
Which AI tools does it support?
Any MCP-compatible AI assistant, including Claude, ChatGPT, and Cursor.
Is my data safe on cloud drives?
Yes. AES-GCM end-to-end encryption ensures that even Sync Vault’s developers cannot read your content.
Is there a storage limit?
No. Sync Vault uses your existing cloud storage. Baidu Drive, Alibaba Cloud Drive and others offer TB-scale free or low-cost storage.
