Moving From Cloud Storage to a Synology
Last verified: August 2026
If your photos and files are scattered across Dropbox, Google, and iCloud - and the monthly bills keep creeping up - you may be wondering about bringing it all home to your own Synology NAS. This guide walks you through it, calmly and safely.
Why People Move Their Files Home
There is no single reason folks bring their storage home. Usually it is a mix of three things that add up over the years. Knowing your reason helps you decide how far to go.
None of this means the cloud is bad. The cloud is genuinely convenient and reliable. The point is that once you own a NAS, you get to choose the balance - and for many families that balance shifts toward home.
- Cost over time. A monthly cloud fee never ends. A NAS is a one-time purchase, and adding space costs far less than years of subscription.
- Privacy. Your files sit on a device in your home, not on a company's servers you cannot see.
- Control. You decide how it is organized, who you share with, and what happens to old files.
What to Bring Home vs. Leave in the Cloud
You do not have to move everything, and you may not want to. Some things are perfect for a home NAS. Others are worth leaving in the cloud for the convenience they provide.
- Your photo and video library, which is often the biggest and most costly.
- Documents and files you rarely need to share but want to keep forever.
- Old archives you are paying to store but almost never open.
Downloading Your Data From the Cloud
Every major service gives you a way to download a full copy of your own data. This is the most direct route: get the files onto a computer, then move them onto the NAS.
These exports can be large and may arrive as several big compressed files. That is normal. You unzip them on your computer, check they opened properly, and then copy the contents onto the NAS.
The Cloud Sync Package
Downloading by hand works, but Synology has a friendlier tool. Cloud Sync is a free package that connects your NAS directly to cloud accounts and pulls the files across for you - no computer in the middle.
You install Cloud Sync on the NAS, sign into the cloud account, choose the folders, and pick a direction for the sync. That direction choice matters enormously, which is exactly what the next page is about.
- Dropbox, Google Drive, OneDrive, and many other popular services.
- It signs into your account and copies the files onto a folder on the NAS.
- It can keep running, so new files that appear in the cloud also come across.
One-Way vs. Two-Way Sync
This is the most important technical choice in the whole move, so I want to be very clear about it. When Cloud Sync connects, it asks which way changes should flow. Pick wrong and you can cause real damage.
For bringing files home, use download only. The cloud stays untouched, so it remains your safety net while you get the NAS copy sorted out.
Moving Photos Into Synology Photos
Photos are usually the biggest reason people move, and Synology has an app made just for them. Synology Photos is the NAS's own photo app - a lot like Google Photos or Apple Photos, but the pictures live on your device.
Once set up, it feels much like the photo app you are used to - albums, search, and viewing from your phone - except there is no monthly bill and the originals are in your home.
- Get your photos onto the NAS - by Cloud Sync, or by copying your downloaded export.
- Point Synology Photos at that folder so it organizes them into an album view.
- Install the Synology Photos app on your phone to browse them anywhere.
- Turn on phone backup so new photos you take copy to the NAS automatically.
Moving Files Into Synology Drive
For your documents - the things that used to live in Dropbox or Google Drive - the matching tool is Synology Drive. It is the NAS's own file app, and it can sync a folder on your computer just like the cloud services did.
The everyday feel is familiar: you work in a folder on your computer, and it quietly syncs to the NAS. The difference is where the master copy lives - your home, not a rented cloud.
- Install Synology Drive Server on the NAS and the Synology Drive Client on your computer.
- Choose a folder that stays in sync between your computer and the NAS.
- Your files are then available on the computer and safely stored on the NAS.
- You can reach them from your phone or from outside the house too.
Keeping a Cloud Copy as Offsite Backup
Here is the smartest move most people miss. Instead of viewing the cloud as the enemy, keep a slice of it on purpose - as your offsite backup. This is the best of both worlds.
You can use Cloud Sync in the upload direction, or Synology's C2 cloud backup, to send a copy of the NAS up to the cloud automatically. A small paid plan used purely for backup is money well spent.
- The NAS holds your files at home, with no monthly storage bill for the bulk of them.
- A cloud copy lives somewhere else entirely, safe from fire, flood, or theft at your home.
- If the NAS ever fails, the cloud copy brings your files back.
Don't Cancel the Cloud Until a Second Copy Exists
This chapter is short because it is one firm rule, and it is worth its own page. The moment you delete your cloud data, you may be left with only one copy - the NAS. And one copy is not safe.
Many people simply keep a modest cloud plan as that second copy and never fully cancel. There is no shame in that - it is the responsible choice, and it is usually cheaper than the plan you started with.
- Move your files to the NAS.
- Verify they open correctly on the NAS.
- Set up your second copy - either an offsite cloud backup or a separate drive.
- Only after two good copies exist should you consider clearing the old cloud.
Planning the Transition Timeline
A move like this does not have to happen in one weekend, and it usually should not. Spreading it over a few weeks lets you check each step and catch problems while the cloud is still there as a safety net.
There is no prize for finishing fast. A slow, checked move is a safe move. The cloud keeps working the whole time, so you lose nothing by taking it a step at a time.
- Week one: set up the NAS, create your folders, install the apps.
- Week two: move photos, then verify a good sample of them.
- Week three: move documents, then verify them too.
- Week four: set up the offsite backup and confirm it runs.
- After that: live on the new setup a while before touching the cloud.
Bandwidth and How Long It Takes
Moving years of photos and files is a lot of data, and it travels over your home internet. It helps to have realistic expectations so you are not alarmed when it takes a while.
A large move can genuinely take days of background transfer. That is completely normal. The good news is that Cloud Sync runs on its own, so you set it going and let it work while you carry on.
- How much data you have - a large photo library can be hundreds of gigabytes.
- Your internet speed, especially your download speed for pulling from the cloud.
- Other use - a big transfer can slow down streaming and video calls while it runs.
Verifying Everything Actually Arrived
This is the step people skip and later regret. A file that copied is not proven until you open it. Before you trust the move, spend real time confirming the NAS copy is complete and healthy.
Only once you have genuinely looked at a good spread of your files and seen them work should you consider the move successful. This is the single check that separates a safe move from a disaster.
- Compare the counts. Roughly how many photos and files should there be? Do the numbers match?
- Open a real sample. Actually view photos and open documents from the NAS, from different years and folders.
- Check the big and the odd. Videos and unusual file types are the ones most likely to have trouble.
- Confirm full quality. Make sure photos are full size, not shrunk copies.
Reorganizing Files As You Move
A move is a rare chance for a fresh start. Rather than dumping years of cloud clutter onto the NAS exactly as it was, use the moment to set up a structure that will actually make sense to you.
Do not let reorganizing stall the move, though. If it starts to feel overwhelming, get the files safely onto the NAS first in their existing structure, then tidy at your leisure. Safe first, tidy second.
- Create a few clear top-level folders: Photos, Documents, Finances, Family, and so on.
- Sort photos into years, or into events that matter to you.
- Let go of duplicates and things you truly do not need - a move surfaces a lot of them.
- Use plain names you will recognize in five years, not cryptic ones.
Sharing Links the New Way
One thing the cloud made easy was sending someone a link to a photo or file. Good news: your Synology can do the same. The sharing lives on your NAS now, but the experience for the person you send it to is familiar.
For sharing to work from outside your home, the NAS needs a safe way to be reached over the internet. Synology offers secure methods for this, and it is worth setting up carefully rather than opening the NAS wide open.
- You can create a share link for a file or folder, much like the cloud did.
- You can protect a link with a password and set it to expire on a date.
- The person you send it to opens it in a browser - they do not need a NAS.
- You stay in control and can turn any link off whenever you like.
Getting Family Onto the New System
If your household shared a cloud plan, the move affects everyone. A little planning keeps the family happy and stops anyone feeling like their photos vanished. Each person can have their own space on the NAS.
The goal is that everyday life feels the same - photos back up from their phone, shared folders are there - just pointed at the home NAS instead of a paid cloud. A short walkthrough for each person makes all the difference.
- Give each family member their own NAS account and private space.
- Install the Synology Photos and Drive apps on their phones.
- Turn on phone photo backup for each person so new pictures are saved.
- Show them where the shared family folder is for things everyone wants.
Comparing Ongoing Costs
The money question is usually what starts these moves, so let us look at it honestly. A NAS is not free - but the shape of the cost is very different from a subscription, and over years that difference adds up.
Over a few years, a NAS often costs less than the subscriptions it replaces - especially for large photo libraries. But do the honest math including a backup, because a NAS with no backup is not really doing the cloud's job yet.
A Sensible Hybrid Setup
If you take one idea from this guide, let it be this. The setup that makes most families happiest is not pure cloud or pure NAS - it is a thoughtful blend that gives you savings, privacy, and safety together.
This is the arrangement I set up for most homes. It captures the real reasons people move - cost and control - without giving up the one thing the cloud did brilliantly, which is keeping a safe copy somewhere else.
- The bulk of your photos and files live on the NAS at home - no big monthly bill.
- A small cloud plan holds a backup copy offsite, safe from anything that hits your house.
- You still share links and access files from anywhere, just through your own NAS.
- Everyday life feels the same, but you own the storage and control the privacy.
A Migration Checklist
Here is the whole move as a checklist you can work through in order. Tick each box only when it is truly done, and you will arrive on the other side with nothing lost.
- Decided what to bring home and what to leave in the cloud.
- Set up the NAS, created folders, and installed Synology Photos and Drive.
- Moved photos - by Cloud Sync (download only) or from a download.
- Moved documents into Synology Drive.
- Verified a real sample of files and photos open correctly and at full quality.
- Set up an offsite backup - a cloud copy or a second drive.
