Complete Guide: Backups between NAS and Google Drive

Last update: August 25, 2026
  • Comparative analysis between the total control of a NAS server and the convenience of the Google cloud.
  • Detailed methodologies for synchronizing and migrating data between local and remote storage.
  • Security strategies to protect files against physical disasters and cyberattacks.

These days, managing the mountain of photos, videos, and documents we generate is a real headache. Many of us start using the cloud because it's convenient, but there comes a point when Google's 15 GB of free storage isn't enough and the monthly fees start to add up. That's where the NAS comes in, that kind of smart hard drive connected to our network that allows us to regain control of our digital lives.

The big question many people are asking is whether it's better to dive headfirst into your own server or continue relying on the tech giants. It's not just about where we store our files, but also about who has the access key and how we ensure that, if something serious happens, we don't lose a lifetime's worth of memories. Let's take a closer look at how to combine the best of both worlds so you're not dependent on anyone.

Clash of the titans: NAS server versus Google Drive

When it comes to control, a NAS wins hands down. Since it's hardware you physically have at home, you can adjust storage capacity , choose drives, and configure security to your liking. In contrast, with Google Drive, you're essentially a guest in their home; you're bound by their policies and payment plans, which significantly limits your options.

However, local storage isn't all sunshine and roses. A NAS is vulnerable to household incidents like fires or floods. Google Drive, being distributed across remote servers, takes that burden off your shoulders. If your home suffers damage, your data remains safe in the cloud, something you could only replicate with a NAS if you had another server in a different location.

Regarding ransomware attacks, both have their tricks. Google offers very powerful recovery tools, but a well-configured NAS with independent backups can be just as robust. Another critical point is long-term data degradation; while Google manages version history automatically, with a NAS you must monitor the lifespan of the disks to prevent file corruption.

How to transfer your data from Google Drive to a Synology NAS

For those who want to stop paying their Google subscription fee and migrate their files to a Synology device, the key tool is Cloud Sync . This application allows you to connect your Google account and automatically transfer all your content to your local server.

  • Installation and linking: First, you need to install Cloud Sync from the Package Center. Once you open it, select Google Drive and authorize access through your browser so the NAS can read your files.
  • Route configuration: It is essential to define the local route (where the data will be stored on the NAS) and the remote route (the Drive folder we want to clone). If you want to copy everything, choose the root folder.
  • Synchronization direction: There are three ways to do this. Bidirectional changes are reflected on both sides; downloading remote changes only brings data from the cloud to the NAS; and uploading local changes does the opposite. For a pure backup, the ideal option is the... remote change download.

A crucial detail is to check the box to not delete files on the destination . If you don't, and you delete something in Google Drive to free up space, the NAS will automatically delete the copy, leaving you without a backup. Additionally, it's recommended to enable the conversion of Google files to Microsoft Office formats and apply file filters to select only what you need, such as photos or music.

Advanced alternatives and external solutions

Sometimes, native tools aren't enough, especially if we want to synchronize the entire system without restrictions. In those cases, services like MultCloud are very useful. It's a cloud-to-cloud management platform that allows you to move data between your NAS and Google Drive without the files having to pass through your computer, which significantly increases transfer speeds.

MultCloud offers various modes, from real-time synchronization to mirror or incremental synchronization . It simply requires creating an account, adding the NAS and Google Drive as services, and running the transfer task. It's a powerful option for those who handle large volumes of data and don't want to rely on their home internet bandwidth.

Tips for beginners and home users

For those starting from scratch, like someone who buys a DS423+, the biggest challenge is often organization. Many complain that massive Google downloads leave files completely disorganized . The solution is to use smart sync tools instead of manual downloads, making it easier for older or less tech-savvy people to access their photos without complications.

If you're on a tight budget and don't need a Plex server or complex features, a single-bay NAS might suffice, although you'll lose data redundancy. For peace of mind, the wisest approach is to apply the 3-2-1 rule: three copies, on two different storage devices, and one of them off-site , either in the Google cloud or on another remote NAS.

Having a hybrid system is the smartest strategy, as it combines the privacy and cost savings of a local server with the disaster recovery offered by Google Cloud infrastructure. By properly configuring one-way synchronization and maintaining off-site backups, we create a digital environment where our memories are protected against hardware failures, human error, and exorbitant subscription costs.
