Rclone Bisync can synchronize changes in both directions between a local Linux folder and Sync.

Unlike rclone sync, which has one source and one destination, Bisync detects changes on both sides.

Note: Rclone considers Bisync an advanced command and recommends reviewing changes carefully because incorrect configuration can result in file deletion or conflicts.

Installation

1. Install and start the Sync WebDAV server. Follow these step-by-step instructions.
2. Install Rclone: sudo apt install rclone
   (or install the latest version from the Rclone website: curl https://rclone.org/install.sh | sudo bash)

Configure Rclone

1. Run: rclone config create sync-webdav webdav url=http://localhost:4918 vendor=other user=sync pass='YOUR_GENERATED_WEBDAV_PASSWORD' --obscure
2. Create the local folder you want to synchronize: mkdir -p ~/Sync

Initial synchronization

The first Bisync run requires --resync.

Start with a dry run:

• rclone bisync ~/Sync sync-webdav:/ --resync --dry-run -v

Review the changes carefully. When you're satisfied, run:

• rclone bisync ~/Sync sync-webdav:/ --resync

Future synchronization

For normal subsequent runs, do not use --resync. Instead, run:

• rclone bisync ~/Sync sync-webdav:/

Changes made locally are copied to Sync, and changes detected in Sync are copied locally.

Important

Bisync is not a continuously running desktop sync client. It synchronizes whenever the command runs.

You can run it manually or schedule it periodically.

Only use --resync for the initial run or when Rclone specifically requires a resync. Using it for every run can cause deleted files to reappear.
