Synology NAS Setup

CopySync can work with your Synology NAS in two different ways: via WebDAV or with direct Synology Drive API integration.

🚀 New: CopySync can now integrate directly with the Synology Drive API. You can connect using the address and QuickConnect ID without dealing with WebDAV.

Part 0: Direct Integration (Easiest Method)

If you have the Synology Drive package installed, you don't need to deal with WebDAV. Simply enter the following details in your CopySync settings:

Sync Method Synology Drive

Address / QuickConnect ID YOUR_ID or 192.168.1.x

Note: This method requires the "User Home Service" to be enabled on DSM.

💡 Synology NAS devices come with a built-in WebDAV Server package. This guide is for DSM 7.x.

Requirements

Security Tips

⚠️

Always use HTTPS. Unencrypted data transfer over HTTP is not secure.

✓

Use a Let's Encrypt certificate. You can get a free certificate from DSM > Control Panel > Security > Certificate.

🔒

Enable 2-factor authentication and consider creating a separate user for CopySync.

Troubleshooting

Connection times out

Make sure port 5006 is open on your router. You can set up automatic port forwarding from DSM > Control Panel > Router Configuration.

Certificate error

If using a self-signed certificate, we recommend switching to Let's Encrypt. Temporarily, your device may need to mark the certificate as trusted.

Access denied (403)

Make sure your user has read/write permission to the WebDAV folder. Check from DSM > Control Panel > Shared Folder > Permissions.
