Looking to boost backup flexibility? Learn how Synology sync to Google Drive allows multiple account integration, making data syncing smoother and smarter.
Quick Search:
Ever found yourself juggling files between your Synology NAS and multiple Google Drive accounts? If so, you're not alone. Many users need to sync data across several cloud accounts but quickly hit a wall with Synology’s default setup. In this guide, we’ll explore how to set up Synology Cloud Sync to multiple Google Drive accounts via built-in feature or MultCloud, giving you the flexibility and control you need.
Before diving into the how-to, let’s answer the “why”. Why should anyone bother syncing Synology with Google Drive in the first place?
Accessibility Anytime, Anywhere
Google Drive is accessible from any device with an internet connection. Syncing ensures your NAS-stored files are available wherever you go.
Data Redundancy and Protection
Backups aren’t optional—they’re essential. By syncing with Google Drive, you protect your valuable data against local failures.
Streamlined Workflow for Teams
Collaborating with remote teams? Cloud-syncing your files ensures everyone stays on the same page—literally.
What is Synology Cloud Sync?
Cloud Sync is a built-in tool in Synology’s DSM (DiskStation Manager) that allows real-time or scheduled synchronization between your NAS and cloud services.
Supported Cloud Services
It supports a wide range of providers, including Dropbox, OneDrive, Google Drive, Amazon Drive, and more.
Here’s where things get tricky.
Account Restrictions
Cloud Sync connects to only one Google account per sync task. While you can create multiple tasks, doing so within a single UI can be limiting.
No Native Multi-Account Sync Support
There’s no out-of-the-box feature in DSM to manage multiple Google Drive accounts easily in parallel, especially not with unified control.
Let’s get into all feasible ways.
Despite the limitations, it is possible to use the built-in method creatively.
Login to DSM and find Cloud Sync in the main menu. Open it to get started.
Click + to add a connection. Choose Google Drive and authenticate using your Google credentials.
Select which NAS folder to sync, set direction (bidirectional, upload, or download), and choose schedule and bandwidth.
To add another Google Drive, repeat the steps above but link it to a different shared folder. This creates a workaround for syncing to multiple accounts.
Pros and Cons of This Method

Here’s where things get easier and more powerful. MultCloud is a cloud management platform that lets you connect multiple cloud services, including NAS, Google Drive, Dropbox, and more—all in one dashboard. You can connect your Synology NAS via WebDAV or FTP and manage its sync behavior through MultCloud’s web interface.
Head to MultCloud.com and register. It’s free for basic use.
In MultCloud, add a “NAS” source by entering your Synology WebDAV or FTP details.
Add all your Google Drive accounts under the Add Cloud section.
Tab Cloud Sync option, select source, and check "Multi-select" to select different Google Drive accounts as destinations. Finally, click "Sync Now" after configuring sync settings.
Advantages of MultCloud for Multi-Account Sync
Let’s make this easy.
Built-in Cloud Sync for Simplicity
If you only have two or three accounts and don’t mind configuring separate tasks, the built-in tool works just fine.
MultCloud for Advanced Multi-Drive Management
If you’re syncing to 5+ accounts or need automation, filtering, and reporting, MultCloud is a no-brainer.
Avoid File Conflicts and Duplication
Make sure your sync rules (upload only, two-way sync, etc.) don’t cause file loops or duplicates.
Monitor Sync Logs Regularly
Always check the logs in DSM or MultCloud to ensure your tasks are completing successfully.
Use Scheduling and Bandwidth Limits Wisely
Don’t choke your internet. Set schedules to run overnight or during low-traffic hours and cap upload/download speeds if needed.
Syncing your Synology NAS with multiple Google Drive accounts via built-in feature or MultCloud doesn't have to be a tech nightmare. Whether you go the manual route using DSM or opt for the smoother, centralized experience with MultCloud, you’ll gain control, flexibility, and peace of mind knowing your data is always accessible and backed up. Choose the path that fits your needs—and let your cloud work smarter, not harder.
1. Can I sync to more than two Google Drive accounts using Synology Cloud Sync alone?
Yes, but you’ll need to set up separate shared folders and tasks for each account manually.
2. Is MultCloud safe to use with Synology NAS?
Yes, MultCloud uses 256-bit AES encryption and OAuth for authentication, making it secure for file sync and transfer.
3. What’s the difference between Cloud Transfer and Cloud Sync in MultCloud?
Cloud Transfer moves data one-way, while Cloud Sync keeps files in both locations updated, supporting two-way sync.
4. Does Synology support scheduling syncs with Google Drive?
Absolutely. You can schedule tasks hourly, daily, or weekly within the Cloud Sync app.
5. Can I sync only specific folders or file types with MultCloud?
Yes! MultCloud offers filters that let you include or exclude certain file types or folders during sync.
