obsync

Use obsync to sync Obsidian vaults on headless Linux servers. Requires an Obsidian Sync subscription and account credentials.

Setup (once)

• obsync login (enter email, password, and optional MFA code)
• For headless servers: export OBSYNC_KEYRING_BACKEND=file
• Optionally set keyring password: export OBSYNC_KEYRING_PASSWORD=mysecret
• Verify: obsync list

Output

• Default: human-friendly terminal output with colors and spinners.
• Use --json / -j for JSON output.
• Use --verbose / -v for debug logging.

Common commands

• Log in: obsync login
• List vaults: obsync list
• Pull vault: obsync pull "My Notes" ~/notes -p "e2e-password"
• Pull and save password: obsync pull "My Notes" ~/notes -p "e2e-password" -s
• Push local changes: obsync push "My Notes" ~/notes -p "e2e-password"
• Watch (continuous sync): obsync watch "My Notes" ~/notes -p "e2e-password"
• Install systemd service: obsync install "My Notes" ~/notes
• Check service status: obsync status "My Notes"
• View service logs: journalctl --user -u obsync@<vault-id>.service -f
• Uninstall service: obsync uninstall "My Notes"

Flags

• -p, --password — E2E encryption password
• -s, --save-password — save E2E password to keyring for future use
• -v, --verbose — enable debug logging
• -j, --json — JSON output to stdout
• --config — path to config file (or OBSYNC_CONFIG env var)
• --version — print version and exit

Notes

• Requires a valid Obsidian Sync subscription.
• E2E encryption uses AES-256-GCM with scrypt key derivation.
• Pull/push compare files by SHA-256 hash — only changed files are transferred.
• Watch mode uses WebSocket for remote changes and fsnotify for local changes (500ms debounce).
• Large files are handled with 2MB chunked transfers.
• Automatic reconnection with exponential backoff (1s-60s) on connection loss.
• The .obsidian/ directory (themes, plugins, settings) is synced.
• For headless servers without a desktop keyring, use OBSYNC_KEYRING_BACKEND=file.
• For always-on sync on headless servers, enable lingering: loginctl enable-linger $USER.
• Config is stored at ~/.config/obsync/config.json.
