Synology NAS Backup Solution That’s Smart and Powerful

admin · Posted on

Today we will discuss Mail Backup X by InventPure, it’s uses, and how it influences your data management choices. It’s a tool for backing up mail on your NAS. The article shows how Synology backup can become a steady, transparent habit rather than a messy chore.

You already live inside folders that carry more texture than most servers admit. Projects evolve through labels, threaded replies, and sudden bursts of context that arrive at odd hours.

With Synology backup running locally, you hold all of it within reach, without detours or dependencies that slow you down when attention is sharp and time is thin.

You want a tool that meets you where you work. Mail Backup X brings a clean, local first approach to Synology back up on your own network, so you add accounts, set rules, and then watch the archive behave like a colleague who never drifts. It’s a system that respects your structure and gives you quick retrieval when a name, a date, or a fragment of a subject line flashes in your mind.

Mail Backup X on Synology NAS — A Practical Guide

1) Let’s start the preparation steps first. Mail Backup X runs in a container, stores all data in the mapped NAS folder, exposes a single web interface port, and relies on a small browser helper to complete OAuth sign-ins for cloud mail providers. And it’s a good idea to set up all these requirements before creating the actual backup profile.

Here are the things you need to properly setup your Synology NAS backup:

  • DSM access with admin rights and an internet connection.
  • Container Manager (Docker) installed on your NAS. If it’s missing, add it from Package Center.

  • A folder on your Synology NAS for backups and app data, for example: MailBackupData.
  • The browser add-on “Mail Backup X OAuth Helper” on the computer you’ll use to sign into Gmail, Outlook, Office 365, or other OAuth accounts.

2) Plan your layout – Before launching anything, decide:

  • Where to store data: create or pick a shared folder (e.g., MailBackupData).
  • Which port to use: default examples use 18080. If that’s in use, pick another free TCP port and write it down.
  • Network mode: bridge is fine for most homes and offices.
  • If you expect very large Synology NAS backups, dedicate a volume with plenty of free space. Although Mail Backup X compresses archives automatically, storage planning always helps.

3) Install and run the container

  1. Open Container Manager on DSM and go to Registry. Search for MailBackupX and select the official image shown in results. Choose the latest tag and download it.

  1. Configure the container:
    • Name the container, for example mailbackupx.
    • Port: map your chosen NAS Local Port (e.g., 18080) to Container Port 18080/TCP.

  1. Volume: add a folder mapping.
    1. Folder on NAS: MailBackupData
  1. Mount path inside container: /data

  1. Enable auto-restart so it comes back after reboots.
  2. Start the container and wait until its status shows Running.

  1. You’ll now reach the app at http://<NAS-IP>:<local-port> from your browser on the same network (e.g., http://192.168.1.10:18080).

4) First-run checklist

  • Sign in to the web app: Default credentials: admin / admin. You’ll be prompted to change the password immediately. Pick a long, unique passphrase.
  • License or trial: Activate a license key or start a trial from the License screen.
  • Install the OAuth Helper: In your browser, add the Mail Backup X OAuth Helper extension. Keep this browser handy when you connect Gmail, Outlook.com, Office 365, or any provider that uses OAuth.

That’s the whole initial setup done.

5) Add your first Synology NAS backup profile

  1. In the left navigation under Backups, choose Setup New Profile. Pick a source. Examples: Gmail, Outlook/Office 365, Exchange, or IMAP.
  1. Click Sign In. Your browser opens the provider’s page. Complete the login and consent screens. The OAuth Helper hands control back to Mail Backup X on your NAS.
  1. Set the preferences for the backup profile:
    1. Name the profile (e.g., “Gmail – Finance”).
    2. Schedule: choose Automatic for continuous capture, or use Manual / Recurring if you prefer periodic runs.
    3. Folder selection: include the folders you want archived.
  1. Create backup profile. The dashboard shows progress and the profile view shows logs and counts.

You can search your archive by sender, subject, date, or any keyword right from the web interface. When you click View Data, a fast built-in viewer opens so you can read emails directly without using an external mail client.

With auto-restart turned on, the Mail Backup X container comes back online automatically whenever your NAS reboots. To update, simply pull the latest image in Container Manager and recreate the container using the same folders and ports. Your archives stay safe because they live in the mapped NAS directory. Keep access restricted to your local network, or use DSM’s reverse proxy with HTTPS if remote access is required. And when backing up your NAS, always include the MailBackupData folder, since it contains both your archives and configuration files.

8) Quick fixes for common hiccups

  • Cannot sign in to Gmail/Office 365: Install the OAuth Helper extension and retry the sign-in flow from the same browser session as the app window.
  • The site does not open: Check the container is Running, confirm the port mapping, and verify http://<NAS-IP>:<port>.
  • No new mail appears: Open the profile, verify schedule settings, and look at the Activities pane for recent runs or errors.
  • Storage creeping up: Compression helps, but large mailboxes keep growing. Expand the underlying NAS volume or plan profile-level exports for old ranges you want to archive externally.
  • All of the above aligns with the Synology NAS edition’s containerized design, default port mapping, first-time login, license/trial screen, OAuth helper requirement, profile setup flow, built-in search/viewer, standard export/import formats, and automatic compression.

That’s it. You now have Mail Backup X running on your Synology NAS, profiles backing up mail on your schedule, fast search and viewing on the LAN, and flexible import/export for legacy or migration needs. All stored in your own folder on the NAS with automatic compression and without any cloud dependency.

What you ask of Synology backup as a daily practice

You want a single place to gather mail from multiple providers without routing through third party clouds. Other solutions often scatter configuration across different screens, hide key controls behind vague labels, or treat a NAS like a generic server.

Mail Backup X aligns its choices with the way a backup Synology NAS is typically deployed at home offices, studios, and compact teams. You keep predictable storage paths and everything on your box. You keep a web panel that feels straightforward after a single pass.

The free trial version is an excellent way to get started and to test the tool for yourself and for your particular needs.
