The best way to backup your Synology: Cloud Station ShareSync

I am finally back posting on this site 🙂

On today’s blog post I want to talk about backing up your synology. There are a lot of ways to do it, but as free services become paid services, things get more complicated.

In today’s blog post I am going to show you how I back up my synology. It might not be the best way if you are on a low budget, but it works as a charm for me. Also, as they holidays are getting close, It might give you an idea for a present for you or a loved one 😉

Back-up methods for Synology

In an early post I describe my previous back up plan, as well as how to back up your synology to an external drive with Hyper Backup or to a cloud service like Azure.

But i have a better way to do it today, and after all the questions I have received on the comments,, I though it would be best to share it with all of you.

As you probably are aware, Synology has changed the back up services to a service they called hyperbackup.

You can access the hyper back up service from the Menu, if you have it installed:

  1. Click on the menu button synology NAS menu button
  2. The old backup button called “Backup and Restore” has been replaced by “Hyper Backup”. Click on it:

hyber backup synology

and you will see they new backup possibilities:

4. Click on the plus button at the lower left hand corner and click on ” Data back up task”:

add data backup task synolgoy

I have showed you on a previous blog post how to back up  to an external drive with Hyper Backup and to Azure.

And that is the way I did it, but when my USB backup disk died, I gave it a proper burial and never looked back. I am doing it differently now and it is the best change i ever did on the synology.

How I back up my data now in my Synology

I have a Synology DS713+ and I love that little machine. I have countless of times talked to my father about it and showed him to (he is tech nerd as me) and I always wanted to give him a synology as a present.

When my USB backup disk died, that is when I thought of it. I can buy a Synology for my backups and put it my fathers house, so I have my own external cloud backup and he has a machine to play with.

WIN_WIN really. Best purchase ever made. Seriously.

So said and done, I bought it, configured it and put it in his house.

As the Synology is a newer model, I made sure to install the disk with a Btrfs format and I then could have Replication on the backup. You have no idea how many times the replication function has saved me from big disasters….like deleting all the content on my synology….(a story for another day). I will talk about replication in another post, promise.

So, it doesn’t come cheap, but it is by far the best method to backup your files,specially if you can place it in somebody else’s house.

So how do I did it?

Back up to another Synology

I have 3 backups to the remote synology:

  1. A hyper backup
  2. Cloud station ShareSync
  3. A replication on important folders

Cloud station ShareSync

And this is my secret: cloud station ShareSync combined with replication is the best backup system I can think of.

Here is how it works, cloud station ShareSync, syncs the folders between my two NAS and the replication makes hourly, daily, weekly, quarterly and yearly copies of it. Amazing right?

You might be wondering why I dont have replication in the synology i have at home. Well, the disk format is wrong…so I need to reformat my drives before I can activate replication in the DS713+.

I am going to that very soon and I will let you know how it went as soon as I am ready 🙂

The setup

Ok, back to business, lets set up the cloud station ShareSync.

To do that, you only need to configure the remote synology.

First, install the app cloud station ShareSync from the package center.

Once you have it, click on it:

2 cloud station share sync

I dont remember if you needed the cloud station server too. I am guessing, you do, but check without and install it if it doesnt work.

Now, you need to configure the connection to your home synology. Click on the plus sign:

add a new nas

and set up the connection as follows:

  1. You synology name: or quickconnect name
  2. Your home synology username
  3. Your home synology password
  4. and enable SSL data transmission.

Select the folder you want to sync and click on the tool:

select folder sharesync

Select the subfolders:

select subfolders sharesync

and select the permission settings:

  1. Two way sync: both synologies can write files on both home and remote synology.
  2. Upload data only: write files from remote to home
  3. Download data only: write files from home to remote (the one I have)

and you are done!! You now have a copy of your data in another synology. :))

Word of caution!

Be careful with this. If you  select option 1 or 3 on the previous step and you delete files from the home server, they will be deleted on your backup copy too. This is why I have replication set up to aviod that.

But more of that on another blog post 🙂

Have a great weekend!!!

  1. Hello, not sure if you can help but I have found that I am no longer able to backup from my Rackstation running 6.1???? to an old DiscStation running 4.2 – any way I can do a sync?

  2. if synology cloud is installed on your computer, does it back up every document you work on even from your desktop, document or flash drive?

  3. Hi Ruth,

    Are you hitting limits on the number of files Share Sync can manage in its database? There’s a white paper on the Synology site that gives recommendations for “optimal” operation — 15K file on a single-core ARM to 200K on a quad-core Atom. I find that I can successfully operate well above these limits, but when you go too far, the slower Synology starts dropping sync events. (White paper:

    What class of Synologys are you running, and how many files are you syncing successfully? I’m running a 1515+, with a pair of (very old) 212j systems offsite. One of the 212js, the one with the greater number of files (maybe 100K), sometimes misses events. So I’m looking at replacing the 212js with a 1517+ or similar. I have around 250K files, +/- 10%, I’d guess.

    Yeah, I set up the environment before I read the white paper…


  4. Hi Ruth,

    What about security? How do you ensure that the files on the remote NAS can’t be viewed by anyone but you, including preventing an admin account on the remote NAS being able to view your files?

    I’m asking the question as I’m currently in the process of backing up to a remote NAS via Hyper Backup and it is unbelievably slow.



      1. Ruth,
        I believe David was asking how to backup to a remote NAS while not trusting the admin account on the other NAS to not poke around your files. SSL would protect against sniffing on the wire, but it would not protect against data at rest attacks (snooping). I believe you would want your home NAS to encrypt the files before sending them over the wire. That way they would be encrypted at rest at the other end. Alternatively, the other end could be set up with an encrypted folder where only you know the encryption key, as shown here. I don’t have a lot (any) experience playing with Synology’s encryption options, but I think this is more along the lines of what the OP was asking.

        Also, thank you for all these Synology articles. They are really fantastic!

  5. Hi Ruth. Thanks for your detailed article.
    Now I got a 713+ as well at home and am wondering what kind of “off-site” backup I should get. The cloud-based ones are nice and prices can be affordable. But the thing there is: you don’t really know where your data is!
    I also was thinking about a 2-NAS strategy, one at my sister’s home. Thinking of this strategy I thought: do I really need a 2-bay NAS anymore? I mean: RAID-1 is fine, but I don’t really need it: if the single HDD in the NAS at home would break, I could go getting my other NAS at my sister’s, right?
    What do you think?
    And also, what’s this thing about “replication”? Could you detail it a bit more?

    1. Hi Flavio,
      YOu only need a 2-bay nas if you have a lot of data or you want to have a raid-2 in your back up nas (which is a good thing), but raid-1 will work.
      Replication is amazing, I have to write a blog post!

      1. Hi Ruth – thanks for your reply.
        Well – lots of data can fit in one 3-TB disk 🙂 That would be fine for me, so 1-bay NAS would be ok.
        RAID-2? Seriously? I never really heard of, I only worked with RAID-1 and RAID-5…

  6. Nice write up, thanks!

    Maybe you can help me with below.

    Right now I am running a local and a remote NAS, whereby my local, running Sharesync, is backing up to remote, running cloud station server, and this is working fine.

    However, I now want to set up a local cloud on my LAN so I can automatically synchronise password databases. I installed DS Cloud on my iPhone, Cloud Station Server is running on my local NAS, but I can’t connect from the iPhone (error 712).

    When trying to access the settings for CS server I find I can’t, the app or settings is nowhere to be found even though my local NAS claims the service is running.

    Am I overlooking something, is there an easier way to do this? Appreciate any input you may be able to give, thanks!

  7. “Be careful with this. If you select option 1 or 3 on the previous step and you download files from the home server, they will be deleted on your backup copy too.”

    Sorry – I tried reading this over and over and I don’t think I understand it. If I set up a one way sync (i.e. backup) – where a remote NAS would “download” (Option 3) from the source NAS, why would it delete on backup remote NAS?

    Unless you meant “… If you select option 1 or 3 on the previous step and you DELETE (?) files from the home server, they will be deleted on your backup copy too.”

    Just looking to clarify. Thanks!
