Local sync

[leadefao]

Hi,
i'm interested in local sync functions but I can only start cloud sessions.
did i missed something?

Hi @leadefao,

Thank you for your question.

Currently, ByteSync doesn't support direct local synchronization out-of-the-box. It is still possible to achieve local synchronization, but it requires running two instances of ByteSync—even if both instances are on the same machine.

I'm actively working on adding direct local synchronization support using a single instance. This upcoming feature will enable managing multiple Data Nodes, each containing one or more Data Sources. Additionally, it will remain possible to synchronize these nodes with remote instances, which themselves can also manage multiple Data Nodes.

Hi @leadefao

Good news! ByteSync now supports local synchronization using a single instance. You no longer need to run two separate instances to achieve local sync.

How it works

When you create a synchronization session, ByteSync can now:

• ✅ Transfer all data locally between your Data Sources (no upload to the cloud)
• ✅ Maintain full end-to-end encryption and complete privacy
• ✅ Use the existing smart delta transfer mechanism for efficient local sync

Current Limitation

While the data transfer itself happens locally, the orchestration and control flow still communicate with the cloud server. This means:

• The coordination logic (session management, synchronization state, etc.) goes through the cloud
• Your actual file data never leaves your local network
• All data remains encrypted throughout the process

This hybrid approach ensures reliable synchronization while keeping your data local. However, I'm planning to add a fully offline mode where even the control flow would be local when there's only one member in the session.

Feel free to try it out and let me know if you have any questions!

Hi,
i've been testing this quite quickly
worked fine!
