Frequently Asked Questions

Quick answers to common questions about the CloudSync desktop agent and sync service.

The sync agent shows "Connecting..." but doesn't sync

Check your firewall and proxy settings. The CloudSync agent needs outbound HTTPS (port 443) access. If you're behind a corporate proxy, configure it in Agent Settings → Network → Proxy. Also verify your account isn't suspended in the web dashboard.

How much bandwidth does the agent use?

The agent uses delta-sync, so only changed file blocks are transferred. For typical office documents, this means a few KB per save. You can set bandwidth limits in Agent Settings → Network → Bandwidth Throttling. The heartbeat check uses less than 1 KB per minute.

Can I exclude certain files or folders from sync?

Yes. Right-click any folder in the CloudSync panel and select "Exclude from sync." You can also create a .csignore file (same syntax as .gitignore) in any synced folder to exclude files by pattern.

What happens if I edit the same file on two devices simultaneously?

CloudSync detects the conflict and saves both versions. You'll see a notification with options to keep one version, keep both (with a renamed copy), or merge manually. The original file is always preserved in version history.

Does the agent work on Linux servers without a GUI?

Yes. Install via our headless CLI package (apt install cloudsync-cli or dnf install cloudsync-cli). Run as a systemd service with systemctl enable cloudsync-agent. Configure via ~/.config/cloudsync/config.toml or environment variables.

How do I uninstall the desktop agent?

Windows: Settings → Apps → CloudSync → Uninstall. macOS: Drag CloudSync from Applications to Trash. Linux: apt remove cloudsync or dnf remove cloudsync. Your cloud files remain accessible via the web dashboard after uninstalling.
