How To Back Up Gmail Email to Synology NAS

synology gmail backup

Are you slowly running out of free storage on your Google account? The 15 GB allotment for Google Drive, Gmail, and Google Photos proves insufficient after using these services daily for years.

What if you primarily rely on Gmail for business correspondence and reach your free quota? Instead of buying more storage, you can leverage a device you already use – Synology NAS – to back up your emails and make more room for incoming and outgoing messages.

You can back up Gmail to Synology NAS using three methods. The following guide covers all the Synology Gmail backup steps and addresses the benefits of backing up Gmail to this secure, cost-efficient storage device.

Benefits of Backing Up Gmail to Synology NAS

A Synology backup for Gmail provides several benefits, including:

  • Freeing up Gmail storage – You don’t need to worry about exceeding the 15 GB storage limit and paying for a quota upgrade to avoid disrupting your email communications. Most Synology NAS devices let you store 16–108 TB of data. You can back up your old (or all) Gmail emails and delete them from Gmail to make more space.
  • Keeping emails in a secure, centralized location – Synology NAS devices provide excellent security, including industry-standard encryption, firewalls, malware and spam prevention, and multi-factor authentication. They can keep your sensitive data safe.
  • Seamlessly restoring Gmail data – Malware in emails, computer bugs, and hardware damage are only some potential causes of corrupted email files. Saving them on your Synology NAS device will prevent data loss.

Now that you know why you should back up Gmail to Synology, it’s time to learn how to do it. These are the best methods to use.

Method 1. Backup Gmail to Synology NAS Using Synology MailPlus

Synology MailPlus is an enterprise solution for storing email from external servers supporting POP3 (Post Office Protocol 3), SMTP (Simple Mail Transfer Protocol), and IMAP (Internet Message Access Protocol) – such as Gmail and Outlook. Besides a browser-based email client, it provides a mail server supporting multiple domains, allowing custom mailbox sizes, and streamlining email administration.

Here’s how to back up Gmail to Synology NAS using MailPlus:

  1. Launch Package Center on your Synology NAS.

Backing up Gmail to Synology using MailPlus is slightly complex, but these steps should help you do it without a hitch. However, the following methods are faster and more convenient.

Method 2. Backup Gmail to Synology NAS With Wondershare UBackit

Wondershare UBackit is a backup manager for Windows for seamlessly backing up emails, files, disks, partitions, and NAS devices. Additionally, it supports disk cloning and lets you schedule and encrypt daily, weekly, monthly, or ongoing backups.

However, UBackit doesn’t back up webmail – you must add your Gmail account to Outlook before using UBackit’s Email Backup feature. Here’s how to do it:

  1. Launch Outlook and go to File.

Method 3. Backup Gmail to Synology NAS AOMEI Backupper Professional

AOMEI Backupper Professional (available on Windows) works similarly to UBackit, letting you back up files, disks, partitions, and emails, perform disk and partition cloning, and schedule incremental, differential, and real-time backups. However, it also supports system backups and provides cloud storage.

Like UBackit, AOMEI Backupper doesn’t back up webmail, so follow the steps from the second method above to connect your Gmail account to Outlook. Afterward, you can back up Gmail to Synology with AOMEI Backupper Professional:

  1. Download and install AOMEI Backupper Professional on your computer.
  1. Launch the program and go to Backup > Outlook Backup. Don’t let the Outlook part confuse you because your Gmail messages will be there after logging into your Gmail in Outlook.
choose outlook backup
  1. Click Add Outlook Data, find your connected Gmail account, select it, and hit OK.

Backing up Gmail to Synology is straightforward with AOMEI Backupper, but UBackit is more affordable. We recommend taking each for a free spin to see how they suit your needs.


Backing up Gmail to Synology NAS is ideal for freeing up your Google account’s storage, avoiding upgrade costs, and saving messages in a secure location. However, some Synology email backup methods are better than others.

Synology MailPlus may be free, but its complexity isn’t its strongest suit. Wondershare UBackit and AOMEI Backupper Professional are faster and more convenient, but UBackit has a more affordable price tag. Leverage their free trials to see them in action and make an informed decision.
