This guide covers 4 reliable methods to backup iPhone to Synology NAS - Synology Photos for automatic photo backup, DS File for manual uploads, computer + NAS sync for full backup, and FoneTool for a simpler workflow. No iCloud monthly fees.
You've been paying for iCloud storage for a while now. Maybe 50GB. Maybe 200GB. It adds up, and your data sits on someone else's servers.
Meanwhile, your Synology NAS has terabytes of space just sitting there. So here's the obvious question: can you just backup iPhone to Synology NAS instead?
Short answer: yes. But not in the way you might expect. Let me show you what actually works.
| ❓ Your Situation | 🎯 Best Method | 💡 Why |
|---|---|---|
| Just want photos and videos backed up automatically | Method 1: Synology Photos | Set it once, forget about it |
| Only need to upload a few files occasionally | Method 2: DS File | Quick and manual - no setup required |
| Want to back up your entire iPhone (app data, messages, settings) | Method 3: Computer + NAS Sync | The only way to backup everything |
| Windows user who wants a one-click solution | Method 4: FoneTool | Simple interface, works with your NAS |
Not sure where to start? If all you care about is photos and videos, jump straight to Method 1. It covers what most people actually need. If you want a full device backup, skip to Method 3.
Here's the thing Apple doesn't tell you: iOS simply doesn't allow direct iPhone-to-NAS backups. You can't just open an app and click "Backup to NAS" like you would with iCloud.
✅ What you CAN backup to NAS:
❌ What you CANNOT backup to NAS directly:
For those, you still need a computer in the middle. We'll cover that in Method 3.
✅ What You Need:
👍 Best for: Most people who just want their camera roll backed up without thinking about it.
Synology Photos automatically uploads your photos and videos to your NAS whenever you're on Wi-Fi, which is super convenient but it only handles media files, so messages, contacts, and app data aren't included.
Step 1. Install Synology Photos from the Package Center on your NAS (if it's not already there). Meanwhile, download it from the App Store on your iPhone.
Step 2. Open the app and sign in using your NAS credentials. Tap More > Photo Backup Not Enabled >Enable Photo Backup and grant access to your iPhone photo library.
Step 3. Choose your backup preferences - Wi-Fi only or include mobile data, backup destination folder, whether to backup all photos or just new ones. At last, tap Enable to backup iPhone to Synology NAS.
New photos and videos will now automatically sync to your NAS whenever you're on Wi-Fi.
👍 Best for: When you only need to upload a few specific files - documents, screenshots, or anything else you want to save.
DS File is Synology's file manager app that lets you pick any file from your iPhone and upload it to your NAS. It's flexible and works for anything, but there's no automation - you'll have to do it manually every time.
Step 1. Download DS File from the App Store on your iPhone. Open the app and sign in to Synology NAS using your NAS credentials.
Step 2. Under the Synology NAS tab, select a network shared folder to save backup files.
Step 3. Click the three dots icon and select Upload. You can then select photos or videos from your iPhone. To upload files, switch to Offline Files.
👍 Best for: People who want to back up their entire iPhone - app data, messages, settings, everything.
This method backs up absolutely everything on your iPhone by first using iTunes or Finder on a computer, then copying that backup to your NAS - it's the only complete solution, but it requires a computer and the backup files are encrypted, so you can't peek inside.
Step 1. Connect your iPhone to your computer with the USB cable. Open iTunes or Finder, depending on which operating system you are using. Then, select your iPhone and click Back Up Now. Wait for the backup to complete.
Step 2. Find the backup file on your computer, usually in the following path:
Step 3. On your NAS, create a shared folder create a shared folder to store your backups. You can name it something like "iPhoneBackups".
Step 4. Copy the entire Backup folder to the previously created NAS folder. You can do this manually, or set up Synology Drive to sync it automatically.
👍 Best for: Windows users who want a one-click backup solution that works with NAS.
FoneTool is for Windows users who want zero hassle. No iTunes, no command lines, just pick your NAS as the destination and click backup. You can even browse what's inside your backup later. (Mac users, sorry, this one's not for you.)

🔥 Top recommendation:
Is Synology NAS does everything? The answer is no and here are some limitations:
1. No direct full-device backup. iOS simply doesn't allow it. This is an Apple limitation, not a Synology problem.
2. No iCloud-level automation. iCloud backs up app data, settings, and messages automatically in the background. NAS can't do that - at least not without a computer in the middle.
3. Photo albums aren't preserved. When you backup photos via Synology Photos, they're sorted by date but your carefully curated albums don't transfer over.
4. Restoring is more work. iCloud restore is one click. Restoring from NAS requires a computer and manual steps.
The hybrid approach that works best:
This way, you get the best of both worlds - iCloud convenience for critical data, and NAS storage for your media library.
Before we dive in, let's quickly figure out if NAS is even the right choice for you.
| External Hard Drive | NAS (Synology) | iCloud | |
|---|---|---|---|
| Cost | One-time purchase | One-time purchase | Monthly subscription, forever |
| Who owns the data? | You | You | Apple |
| Access | Plug into computer | Any device on your network | Anywhere with internet |
| Automatic backup? | No | Yes (photos/videos) | Yes |
| 👍 Best for | Simple local backup | Multi-device family backup | Convenience, don't want to think about it |
Here's my take:
Q1: Can I backup my iPhone directly to Synology NAS without a computer?
No, not for a full device backup. iOS doesn't support direct iPhone-to-NAS backups. But you can automatically backup photos and videos using Synology Photos, and manually upload files using DS File.
Q2: Does Synology Photos backup my entire iPhone?
No. Synology Photos only backs up photos and videos. It does not back up messages, contacts, app data, or system settings.
Q3: Can I backup iMessages to Synology NAS?
Not directly. The only way is through a full iPhone backup via iTunes/Finder on a computer, then syncing that backup to your NAS.
Q4: Is backing up to NAS cheaper than iCloud?
Yes. NAS is a one-time purchase. iCloud charges monthly fees forever. Over time, NAS pays for itself, especially if you have multiple devices backing up to it.
Q5: What's the difference between backing up to NAS vs. an external hard drive?
NAS is accessible over your network - any device at home can reach it. An external hard drive is portable and doesn't require a network, but you have to physically connect it to a computer.
