Synology Diskstations are used in homes and organizations to store a large amount of data in a central storage location, which can be accessed by users through a LAN (Local Area Network). The idea is to provide single copies of files for multiple users. We’ve gathered the top five cloud backup services to help do just that.

It’s obvious that Synology devices store a large amount of data and losing that info could be disastrous. For home users, Synology NAS devices can be used to save:

  • Multimedia files
  • Security systems
  • Smart TVs
  • Other devices

While for organizations, these devices can be used to access data from a centralized location. Mainly because as a centralized location for data storage, there is no duplication. That is why it becomes vital to backup data on Synology devices.

While there are many online backup services available, ones that offer backup for Synology devices are surprisingly few. Plus, since you’re probably going to backup a large amount of data, it’s also important to choose an affordable and secure cloud backup service. To help you make the right decision, I have curated five of the best cloud backup options for Synology.

How This Article is Setup

I’d like to take a second to explain how this article is setup and its purpose. This article is not a full review of each service, rather, I’m trying to present:

  • A summary of each Synology backup service
  • A small snippet about why I liked each one
  • A list of pros and cons

Of course, after reading this piece, I do advise that you take the time to try out each service’s free offer, whether it be a trial period or free account. Before you make a final decision with whom to backup your Synology NAS device with.


With CrashPlan, you get unlimited storage for $5.99 per month, and that is one of the reasons, among many others, why this cloud backup service is at the top of our list.

Crashplan vs Carbonite: Is This The Best Service

Backing up Synology drives through CrashPlan isn’t as easy as backing up data from personal computers. It takes a little bit of research, and I would recommend doing it with someone who has handled things like this before. Since CrashPlan is based on Java, the first thing you need to do is install Java on your system.

Download CrashPlan, then install it and start Synology via its web interface.

If you’ve already downloaded the backup service, it should be visible in the package center. Yes, it can all be a little confusing the first time around, but if you are using a Synology device, I am pretty sure you are already used to this. Plus, I am confident you wouldn’t mind spending a few extra minutes backing up files, if it means securing your data. CrashPlan also retains unlimited file versions and deleted files are easy to recover.

Why We Like CrashPlan:

Let’s touch on security; CrashPlan offers several layers of protection to make sure your data is always safe. First, there is an account password, and apart from that, CrashPlan also provides 448-bit local encryption, the key to which is set by a user. This key never gets sent to CrashPlan’s server, as data is encrypted first on your local machine and then sent over to their server.

  • Unlimited file storage
  • Integrates with Synology devices
  • Private encryption


  • Complicated installation process
  • Lacks syncing or sharing options
  • Difficult to handle for novices


ElephantDrive comes pre-installed on many Synology disk stations. Synology backups are available on all the tiers, including the lite one, which offers 2GB of free storage. ElephantDrive comes integrated with Synology drives, which means you don’t have to worry about handling backend stuff, and setting commands to backup a Synology drive.

You first need to access and install Elephant Drive on a system by going to the Package Installer through DMS.

As soon as you click on it, a setup wizard will open up to guide you through the installation process. And that’s it; there’s nothing else to do. The cloud backup service supports 10-series to 16-series of Synology devices. Apart from the free 2GB plan, paid plans start at $9.99 per month for 1TB of data, and $39.95 per month for 2TB of data.

ElephantDrive also provides features like scheduling, incremental backup, continuous backup and bandwidth throttling. This cloud service is available through desktop, web, and mobile apps as well. While there is no file synchronization, file sharing is still an available option. It retains unlimited file versions which can be accessed by users later.

Why We Like ElephantDrive:

ElephantDrive’s privacy options are impressive too. As ElephantDrive uses Amazon S3 servers to store data. Then there is 256-bit local encryption, and I strongly recommend setting a personal encryption key. There is 256-bit server encryption as well.

Overall, ElephantDrive is an excellent cloud backup option for Synology devices. Especially with the first 2GB being free, but if you have more than 1TB of data to backup, and you don’t mind the extra work, I recommend CrashPlan instead.

  • Supports Linux now
  • 2GB free storage

  • Expensive for large data backups
  • Limited backup settings
  • Capped 5GB file uploads
Starts from $ 833 per month for 1000 GB
Free plan available Save 16 %


HiDrive is powered by Strato, one of Europe’s biggest web hosting services. With an initial 5GB free plan and direct integration with Synology devices, it’s a great option for backing up data.  While the desktop client is very easy to use, it lacks the option to schedule backups or automate them. And this can be a big problem for users who have a significant amount of data which needs to be backed up.

On the flip side, file sharing is an option with HiDrive. Users can create links and give recipients read-only or editing access. Paid plans provide the option to set passwords for file links. HiDrive doesn’t exactly save different versions of a file; it takes snapshots of the entire backup, at specific time intervals.

In the settings, you can choose at what intervals you would want HiDrive to create these backup snapshots. Unfortunately, security lags big time with HiDrive. There is no private encryption, which is disappointing. In fact, there is no server-side encryption either. Files are encrypted when there are in transit, with an SSL encryption. The website and desktop clients also seem to have limited features.

Why We Like HiDrive:

You can install HiDrive on your system if you want. But in most systems, it already comes installed as an add-on, providing a quick way to backup data. It’s one of the few cloud backup services that Synology itself recommends.

If you have photos, you can create photo albums online and share them. I would also recommend this service if you want a pre-installed backup service and don’t have much data to backup.

  • Free 5GB of storage space
  • Comes installed on Synology devices
  • Can do file sharing


  • No private encryption
  • No backup schedulin
  • Isn’t as sophisticated

Glacier Backup

Powered by Amazon, I can say that Glacier Backup is one of the most reliable and affordable services on this list.  It’s in fourth place because it is a very basic backup service, and it can be a little tricky to handle if you’re completely new to Synology disk station and Amazon Glacier. By basic, I mean the service can’t retrieve a file you accidentally lost, or recover a small folder.

When Glacier starts extracting, it takes a long time, since data is retrieved all at once. Glacier is a secondary backup solution which you don’t want to use that often. A perfect fit for Synology users with big archives which need to be secured.

I have to mention this, there’s no app provided which can download or upload data, third-party apps are assigned that very vital task — and work just like any other cloud backup app. Glacier has features like bandwidth throttling, file syncing and scheduling. The pricing varies from $0.007-0.113 per month per GB, and exact pricing depends on the data center you choose to store data inside.

Why We Like Glacier Backup: 

Glacier uses  256-bit AES encryption on the server side — to protect data. There is no private encryption, but you do get an access ID and key upon sign up. You have to enter these credentials along with your main credentials, to log in to an account.

If you do not want to store data in U.S. data centers, you can choose to move it to Europe or Asia. And that is a significant advantage of Glacier.


  • Cheap & affordable pricing
  • Highly reliable
  • Choose your own data center


  • Difficult to navigate for novices
  • Very basic backup features
  • No private encryption


Symform gives all its Synology users 10GB of free storage space, with no strings attached. According to the company’s website, this space can be extended to ‘unlimited free’ storage space, by volunteering your extra Synology storage to Symform.

While testing cloud storage services, there is one lesson I’ve learned – ‘free’ and ‘unlimited’ never go hand-in-hand. So I started researching more about Symform’s unlimited free storage claims. It turns out, for every 1GB of Synology space given to Symform; you get 2GB of cloud space back.

So technically, there is no free unlimited storage, even if you contribute 1TB of space, you’ll only get 2TB of cloud space back. You can also opt for paid plans which start at $10 per month for 100GB of data, and the highest storage plan available is for 1TB, which costs $100 per month.

Also, it’s a little weird giving personal space to a cloud backup company; you never know how they are using it.

Why We Like Symform: 

Since Symform has teamed up with Synology, installing its app is as easy as ElephantDrive’s. You can directly find it in the Packet Manager. There is also 256-bit AES encryption on the server-side, but there isn’t any private encryption available.


  • Free 10GB storage
  • Storage exchange program
  • Easy installation


  • Paid plans are very expensive
  • No private encryption
  • Lacks file versioning/sharing

In Summary…

Synology Diskstations are good at storing large amounts of data, and backing them up is just as important as backing up your personal computers. It’s an unfortunate fact that not many good backup apps exist, which can cater to the needs of Synology users.

Nonetheless, I’ve tried my best to find them. And as you can see, choosing the right cloud backup service will depend on how much you are willing to spend, and how much time you have to maintain these services. Feel free to share any thoughts or comments you may have below, and thanks for reading!

20 thoughts on “Best Cloud Backup for Synology 2020”

  1. Crashplan doesn’t work on on intel based Synology Devices like a DS414 (arm) because the packages were removed. And it has been reported that the Crashplan App crashes every time Crashplan changes things on their side and often some tricks and workarounds are needed to get it back working. Some user wrote in forums that they wonder if it still works after 1-2 weeks. That’s not what I would call a real option

    1. I agree with these remarks – frequently when operating system updates are implemented this breaks totally CrashPlan – and it remains broken until a third party publisher updates it. This is a very significant single point of failure.

      It is because of this that I am reading your article in a bid to find a reliable alternative. I would not recommend CrashPlan as a serious option for Synology NAS backup.

      1. Same.
        I am reading this article because life is too short to be spending an hour or more every few weeks reworking out how to get CrashPlan on a Synology going again.

  2. lack of native Crashplan support is the reason that I am looking at QNAP. I prefer Synology, but backup is important and there are no affordable, reliable options for Synology devices.

    1. Qnap running in headless mode has a few issues. The qnap release version tends to be a rev behind so when Crashplan updates, you either need to use a workaround install the official release of crashplan or you need to find the old version of crashplan to install on a PC as the head and redirect to manage the Qnap.

      If there’s an easier way on the Qnap, I’ll be glad to learn it?

  3. I support a client using CrashPlan Pro to backup their Synology. While the price is great, and features (security, recovery, versioning, dedupe) are very good, the configuration is convoluted… the Synology CP client needs to be “forwarded” to a desktop (Win/Mac) with the CP client installed… and when Synology updates occur, the config frequently breaks and has to be redone.

    I feel bad having to charge my client every time this happens, since the savings in hosting are offset by the cost of support (but, nobody on their staff has the understanding or time to deal with the unit).

    But it does seem CP is prevalent in the Synology community… like others, I’m looking to see what alternatives are out there.

    1. I read a lot of good posts recommending it. Check out Mike Tabor’s blog for details ( I gave it a try and initially was impressed. But I discovered the backup/sync job went completely missing a few weeks later. I rebuilt the job and 2 days later the job got deleted again. Now, I don’t think this is a Backblaze problem. More likely there’s a bug in Cloud Sync. Unfortunately, I don’t think there’s a way to get it reliably working with the other backup apps Synology offers. So as far as I’m concerned, Backblaze isn’t an option until Synology addresses this issue.

  4. Synology are bringing their own cloud backup solution to market.
    It’s currently in BETA, I’m trailing it at the moment but so far it’s very good.
    Strongly suggest any Synology users give it a try.
    Can’t confirm prices but have heard rumours they are going to be competitive.

  5. Seems Crashplan is closing down the consumer version soon. Need another option before October!

    1. - Chief Editor

      Yeah, they kinda sprung it on us, too, though do note that’s October 2018.

  6. I run a VM with Ubuntu on it and use the Crashplan client to backup my Synology NAS via CIFS mounts (could do NFS too). I was using the consumer version and am now using a single license pro version for close to the same cost. I have over 4Tb I back up and switching backup solutions would mean backing up all that again which would take a long time. Crashplan, even with retiring the consumer version, is still the best solution for me to back up my Synology.

  7. Also, I think the author made a mistake about the inability with Glacier to restore a single file. I also back up to Glacier (I like having multiple backups) and have successfully restored single files before.

  8. Does anyone have any experience with iDrive for Synology? It seems to have a lot of rave reviews for PC backup, and i’ve just seen that it has a Synology package app also. I have a DS415PLAY.

    1. I’m an IT consultant in Denver CO. I have 10+ customers with Synology NAS boxes, all using iDrive to back them up. iDrive is a little bit tricky to install on a Synology NAS, but works very reliably, and makes it quick and easy to restore files.

      I used to use Glacier, but had a VERY bad experience with them. Had a client hit with an encryption virus, and all of their files got encrypted. Had to restore 4+ TB from Glacier. Previously I had restored at most 1-2 GB from Glacier, and while it was slow, it wasn’t too bad – on the order of 3-4 hours. The large restore took at least 1 week to complete, and we then discovered to our horror that about 30% of the restored files were corrupted. I have no idea if this is the fault of Glacier or of Synology’s Glacier client, but needless to say, I’ll never use Glacier ever again.

  9. I have been screwing with Crashplan for Small business for three weeks. It will not reliable backup my NAS, and they won’t take ownership of helping me get it working properly. One helpful Email every other day does not constitute good customer service.

  10. Seriously now why does one wish to be locked in a monthly cloud money wasting exercise when you can get two RAID configured synology boxes or any linux boxes, place them remotely and sync them overnight. No more corruptions, wasted money, full confidentiality, encryption, heart attacks on recovery… fast reliable backup for the masses.
    When you have a lot of data cloud is also very very expensive.


      I like the thinking, but not everyone has remote locations to store Synology boxes. Businesses might, but most businesses are also more equipped to handle the costs of storing files in the cloud, even going with a pricier solution like Microsoft Azure. Coupled with CloudBerry Backup, you can encrypt your files privately and the speed should be excellent thanks to the fact that Azure has dozens of data centers around the world. Different strokes for different folks. There are some other concerns with your suggested approach, too, such as making sure your remotely stored NAS is kept online, not to mention the fact that you’d have to pay for internet service to keep it running.
