Synology Active Backup for Business Review and Walkthrough

Previously I’d already covered Synology’s Microsoft 365 Backup software which I was a big fan of, for simplicity of use and an incredibly cheap price point for a small to medium business as a Microsoft 365 data backup solution.

This time, I’m looking at Synology Active Backup for Business on their new DiskStation 1621xs+. Just like Microsoft 365 Backup, Active Backup for Business is free as long as you have a supported DiskStation model:

The support goes a long way back years wise, which is great to see. They have a comprehensive overview of this application and it’s abilities, but I’ll cover it all more briefly here while sharing my experience setting each type of backup up.

Installing the software on a Synology DiskStation is easily done via Package Center and a very quick activation process that requires a free Synology account:

After activating, you’ll immediately see the overview screen. At a glance, it gives a good idea on the sorts of things you can back up:

PC and Physical Server backups

Backing up a physical PC or Server is pretty easy, and the wizard takes you through the steps. Windows 7 SP1 and above is supported, as is Windows Server 2008 R2 and above, and needs the ‘Synology Active Backup for Business Agent’ installed. After a next, next finish, install, you’ll need to specify the IP/name of your DiskStation, and username/password:

After connecting and confirming the details, the PC is registered against Active Backup for Business, and the agent continues to run in the tray:

The agent will show when you last backed up, and if a backup is currently running:

No backups will run yet though, because we need to create a backup task back on Active Backup for Business. Again, a wizard will take you through this and let you choose what options you’d like for backup. I’m going to just back up everything, with the data compression and encryption options (which are default)

You then define when you want your backup to run – manually, or on a schedule:

I do quite like some of the options here – backup by event of screen locked or signing out is a nice way of making sure it doesn’t interrupt someone using the PC and slow things down while they’re actually working. Also having backup windows, so you can block out the working day if needed.

Next is the retention policy, a good way of reducing space taken – is there a difference between a backup 5 months ago vs 5 months and 1 day? Probably not, and very unlikely that you had something worth restoring on your PC only for 1 day.

At the end of the wizard and a summary screen, you have the option to back up now. I kicked this off, and the agent immediately showed the progress and events related to backing up.

This was a really easy and painless setup to back up a PC, but what about restoring? You can either create recovery media for a full restore, or you can use the Restore Portal to navigate through backups and pick what you’d like to restore:

The bottom time line lets you pick from what point in time you’d like to restore, with a dot showing each available time point.

Then, you can navigate through the disk you need, and go through the folders which match the file structure at the time of backup. Once you’re on the single file, multiple files or folder you want to restore, you can choose the “Restore” option to put the files back in their original location, or somewhere else, and decide if you want to automatically overwrite existing files or not.

Download however, will just download the file you selected like any other browser based download, or multiple files will come through as a single ZIP file.

File Server Backups

If you don’t want, or can’t have an agent on a file share, you can instead remotely back up via SMB or rsync:

After entering the remote server details:

It will verify they work, then let you set up a task:

The options are Multi-versioned, Mirroring and Incremental. They cover the different scenarios you might want to use – Multi-versions will take up the most space, where mirroring can only ever be as big as the source files, and incremental is half way between the two, without the versioning component:

You can then choose what to back up in the file share:

And then finish creating your task by giving it a name, telling where to backup the files to locally, and set a schedule.

The other option you’ll notice here is ‘Enable CSS for SMB File Shares’. If the source share supports this, then the backup can be taken without interruption to access of these files, which has been fairly standard for a while – so turn this on if you can.

The restore process is pretty much the same as PC / Physical Server, so I won’t go into detail on that part.

Virtual Machine

Both VMWare Hypervisor and Microsoft Hyper-V are supported Virtual Machine platforms. As I haven’t touched VMware for years, we’ll look at Hyper-V only. It’s worth noting that cross platform restores are supported – you can restore a Hyper-V VM to VMware vSphere too.

Creating a Hyper-V backup is again an easy process:

First, you’ll need to put in the Hyper-V Host details. If you’re trying to back up VMs on a Windows 10 laptop you have, there’s a few small requirements:

Set up WinRM by running ‘WinRM QuickConfig’ in an elevated command prompt. You’ll need to make sure none of your network connections are set to ‘Public’.

Have a local admin account ready to use, and allow SMB2 through the Windows Firewall by allowing ‘File and Printer Sharing’ on Private networks.

The Hyper-V Backup Task wizard will give you hints as to where you might be stuck, and at the end you’ll have your host listed:

The Hyper-V Virtual Machines will then be automatically detected and listed, but they’re not configured for backup yet – we need another task. Clicking ‘Create Task’ will start by asking you where you want your backups:

Then you can choose the Hyper-V VMs to back up:

One selecting, we have several settings we can configure:

The default options are shown.

Maximum quantity of concurrent backup device(s) can be up to 10.

Enable Changed Block Tracking – Only transfer blocks that have changed since the last backup, rather than all blocks to reduce backup times drastically.

Enable application-aware backup – Use Volume Shadow Copy to ensure consistency with backups

Enable data transfer compression – Suggested for slow networks to improve transfer rates

Enable data transfer encryption – Self explanatory :)

Enable source datastore usage detection – to prevent running out of space

Enable backup verification – Checks the backup when complete

Once you’ve selected the options you want, you’ll see the familiar Schedule Backup Task window, retention policies etc:

I always prefer an agentless backup where possible, so it was good to see no agent was required to backup Hyper-V VMs.

Backing up a Windows Server 2019 VM was rather quick – especially since the laptop hosting the VM was connected via Wifi.

Restoring is again pretty simple, you can navigate to the location of the backups and see a copy of the vhdx for each VM, with other files I expect keep other incremental change data:

The Restore Wizard starts by letting you pick witch platform you’re restoring to- Synolgoy Virtual Machine Manager gives extended options for management and recovery and is recommended for flexibility in production environments. For a lab, you should be able to get away without it:

Restore Type – Instant Restore and Full Virtual Machine Restore are the two choices:

You can then pick which VMs you want to restore and which restore points:

Restore Mode lets you choose if you’re replacing the current live VM, or restoring to a different location as a copy:

Finally, the summary screen with the option of automatically powering on the VM when complete.

Phew! That’s the runthrough of the backup types and restore options Active Backup for Business supports.

The dashboard gives a great ‘at a glance’ overview of everything going on, and we even have de-duplication of data! This is what it looks like with some real data in it, compared to the first screenshot of this post:

There’s a bunch of other first party Synology apps available too:

Plus third party apps:

And with solutions like Docker, you can use your Synolgoy to host many other solutions available in containers, and run them off this little black box.

I’ll say the same thing about Synology Active Backup for Business I did in my Synology Microsoft 365 Backup Review – this is pretty impressive for ‘free’. Yes, you have to buy the Synology DiskStation itself, and you’ll need disks, but that’s it. Even if you use it as a single nightly backup for having a local and quickly accessible restore point to provide as much business continuity as possible, it’s an entire solution at an incredibly cheap price point.

Because you can do both Microsoft 365 data AND Hyper-V VMs on this single device, it should be an option that any small to medium business should investigate. The interface is easy to use, the logs show detailed information about what’s going on – and even for a home business setup, it’s very much a set and forget event.

Azure AD Password Protection Setup Summary

Microsoft have a nice way of preventing the use of bad passwords. Yes, all passwords are bad, but some are worse than others :)

Azure Active Directory Password Protection is a service that looks at password changes and blocks passwords it deems as weak. This could be from checking it’s an easy password to break using a dictionary attack, or other easily guessable variants. It leverages Microsoft online services to do so, which requires some setup and agents installed on the on-premises environment.

Microsoft’s documentation for this is detailed and fairly easy to follow, but I thought I’d do a quick rundown.

Installing the agents:

  • There are two agents – the ‘Azure AD Password Protection DC agent’ and the ‘Azure AD Password Protection proxy service’. Both can be downloaded here.
  • The ‘Azure AD Password Protection proxy service’ needs to be installed on all Domain Controllers (DCs), but the ‘Azure AD Password Protection proxy service’ only needs to be installed somewhere once. You CAN install it on a Domain Controller, and you can install it on ALL Domain Controllers, but Microsoft highlighted this as a potential security risk allowing any DC internet access. At least two installs of this is recommended for redundancy.
  • The ‘Azure AD Password Protection proxy service’ can’t be installed alongside (on the same server) as ‘Azure AD App Proxy Service’ – which is probably the same utility server you’d think of putting this on.
  • After installing the ‘Azure AD Password Protection proxy service’ you’ll need to run a few PowerShell commands to register it with global admin rights – you don’t need to create a service account for this, it’s just a one time registration process.

    The commands are:

    Register-AzureADPasswordProtectionProxy -AccountUpn ‘’
    (run this on each install)

    Register-AzureADPasswordProtectionForest -AccountUpn ‘’
    (run this after the first install only)
  • Installing the ‘Azure AD Password Protection DC agent’ is easier again, but will need a reboot of the DC to start working.
  • Both clients automatically update themselves.

Configuring in Azure Active Directory

  • You’ll need to enable on-premises Azure Active Directory Password Protection on the Azure AD portal – that link should take you right to ‘Password Protection’ but it’s located under Azure Active Directory > Security > Authentication methods > Password protection.
  • Start with ‘Audit mode’ rather than ‘Enforced Mode’ so you can get an idea of how many users might get affected by this change, and allow you to communicate this out before forcing.
  • You can also add custom banned passwords which might include your company name and common terms in your business and industry, to ensure easily guessed passwords aren’t used.

There are other catches to this, like making sure your domain is using DFSR rather than FRSR so please go through the official documenation carfeully.

Once set up, you can either read through the logs on a DC, or run this PowerShell command on each DC to see the results.:


You’ll need to either wait for users to change their passwords, or do some yourself and work out which DC the changes were done against. These stats will give you an idea of how many ‘failures’ were audited, so you can decide how much of a user impact enforcing the policy will be.

You could of course ship these event viewer logs to a central repository, but the service should just do it’s thing and just block users from setting a new password that’s really bad.

Conditional Access Baseline Policies Out, Security Defaults In for Azure Active Directory

Something I stumbled across today – it appears that Microsoft has decided to abandon Baseline Protection Policies, and replace them with a single ‘on/off’ switch called ‘Security Defaults’

Baseline Protection policies (also called Baseline Policies, it seems both terms have been used) were in preview, and were a pre-canned set of policies based on Microsoft recommendations on standard security settings that should be in place – such as forcing any administrator account to use MFA at each sign in, and blocking legacy authentication.

Here’s what the Conditional Access page currently shows. There might be something wrong with the detection though, as I clearly have a Baseline Policy enabled:

It’s not difficult to recreate the Baseline policies, so I’d suggest migrating off of them now while they’re still functional – you don’t want to be left in a state where you didn’t realise MFA for admins was now not being forced.

The replacement Security Defaults option can be found by going to Azure Active Directory > Manage – Properties > Manage Security Defaults (it’s not in the Conditional Access area):

Before flipping this switch to ‘On’, you’ll need to have a really good read of the documentation. There’s a lot this option does, and may break many environments who aren’t ready for this – such as making sure you have no Legacy Authentication requirements, and that all users will register for MFA within 14 days or be blocked from sign-in until they register.

Although I can see this option being turned on by an uninformed administrator and causing some chaos, I like the idea of this. It means a new tenant can now have a single option to start with to implement several critical aspects to protect the tenant against attacks – right now there’s a lot you need to go through to lock it down, and especially for a small business who doesn’t have the time or resources to do this as well as a larger one, a single on/off switch solves a lot of security problems.

Security Defaults is also available to all customers on all tiers – Azure AD Free tier, which means those who have basic needs can now be protected in several ways they weren’t able to do via Conditional Access before.

Security Defaults isn’t listed as being in Preview as far as I can tell, so it may be an option that’s just rolled out and a ready to go. I am guessing there’ll be a bit of kickback around this being a single option that has no other configurable options in it, so we’ll have to wait and see if the product changes, or Microsoft’s vision of a security toggle stays as their goal.

CIAOPS Academy

Today I’m sharing Robert Crane‘s CIAOPS Academy service. He’s an Australian based Microsoft Office Servers and Services MVP, and seems to be rather busy with all his different projects, including the CIAOPS Need To Know podcast.

That podcast I highly recommend as an easy way to keep on on the latest Office 365 and Azure news. Even though I try to keep on top of it myself, they often raise other new features or changes that I hadn’t come across yet.

Beyond that though, the CIAOPS Academy is a service I personally pay for that Robert provides. I am on the lowest tier, but the private Facebook group that Robert runs is an invaluable source of fellow professionals who ask and help all things in the Microsoft tech space.

It’s different to other communities with it’s paywall, as everyone is invested and cares about the topics raised.

There’s also a referral program for signups – sure you can use my affiliate link to CIAOPS Academy or use one that doesn’t help me pay for my own access here. I’m not one to suggest services or products I don’t believe in myself, but I’ve had several questions raised already which has more than paid for the service in my mind.

The bronze level (which is what I use) is enough for me right now, but higher levels give you access to videos and other training materials.

The bonus news I can share here is that there is now a 7 day trial available, which is mentioned at the bottom of the patron page above. If you want to see what it’s about and check it’s worthwhile, you can now do it for free!

In summary, if you’re someone who is either new to, or currently managing Office 365 and Azure, this is a great group of people to be a part of. I’m not the only other Microsoft MVP there, which I think shows the value of this service.

Azure AD B2B PowerShell Invites

I’ve written about Azure AD B2B before, as well as then giving those invited users access to SharePoint Online, but there’s been a lot of changes since I started using it. Have a read of my original article if you’re interested to see how I’m using B2B and why.

Azure AD B2B is still in preview, but in Feb 2017 a bunch of improvements were added. Part of these changes were around using the new Azure portal rather than the Classic Portal, and with that is the removal of inviting users via CSV file and uploading it to Azure AD. This was exactly the way I was using it, so I had to change to one of the newer methods.

Although CSV support is gone, it’s been replaced by PowerShell which can just call the same CSV file being used before, so it’s not a huge change. There’s a PowerShell example on this technet page which shows how to do it. There is a catch though, the ability to add the user to groups as part of the import is gone.

The other big change that impacted me was the invitation emails. This is the email that gets sent to the recipient when being invited – it was originally a plain text email from a generic Microsoft address, but it’s now changed to a much more professional looking email. The catch with this is, rather than coming from a generic Microsoft email account, it now comes from the user that sends the invites out. I found this out the hard way when invited parties started seeing my details and photo with the invite!

There’s four approaches I can come up with around this new invite method –

1. Leave it as showing the admin user who does the invites (not ideal)

2. Create and use a seperate service account for these invites, so it comes from a generic looking internal email address (quite good)

3. Get the users themselves to send the invites out – by default, all users have access to invite others to their tenant (worst option, users won’t do this themselves, need training and support, can’t automate)

4. Use APIs and send the invites out on behalf of the user (‘best’ option but requires the most work, most complex)

While I look at option 4, option 2 is a good middle ground and will probably do for most companies.

I’ve written and tested the below script, which works on a single user by user basis. This uses just the Azure AD Preview module for PowerShell, which is at version at the time of writing. To use the method mentioned on that page to install, I had to first install Windows Management Framework 5.0.

$group = get-azureadgroup -SearchString "Put your exact search string here" | where {$_.dirsyncenabled -eq $null}
$newuser = New-AzureADMSInvitation -InvitedUserEmailAddress -InvitedUserDisplayName "Full Name" -sendinvitationmessage $true -InviteRedirectUrl ""
Add-AzureADGroupMember -objectid $group.objectid -RefObjectId $newuser.InvitedUser.Id

This script requires you to first authenticate against Azure AD with the command connect-azuread : the same way you’d use connect-msol for Office 365. More on how to automate that part in an upcoming blog post.

I’ve written this on the basis that you already have a group to add the guest user into, which gives them the permissions required after being invited into your Azure AD tenant. It’s also more a proof of concept script, which shows how to automate these steps enough to then be able to do what you want with it – such as wrap it around a ‘for each’ and feed multiple users into it.

The first thing the script does is get the group name. As objects in Azure AD don’t have to have unique names like on-prem Active Directory, this script will fail if it finds multiple results the same. It’s also making sure the result that comes back is only a cloud based group, because you can only add B2B invited users into Azure AD groups (not ones synced from on-prem).

Next it will send out the invite to the user. This is the important part. If you don’t want an email to go out, you can change the -sendinvitationmessage value to $false.

Finally we’re adding the invited user into the group by ObjectIDs of each object – straight forward.


The end result is a user who will be able to accept their invite, log in and have access to whatever they need to. Note that the way I do this is by having an app and advertising it to the group that also gives permissions to SharePoint Online, so they’ll see the single link on their page.

If you’re mucking about with Azure AD B2B this should give you somewhere to start. The Microsoft Technet pages for Azure AD are very comprehensive now as well as being easy to read, so check them out.

If you have any questions on Azure AD B2B feel free to ask!

Update 23rd August 2017

I’ve now gotten around to making a mass invite script. I used Eric Schrader’s script, and made some of my own modifications.

It will pick up a file in the same path as the script called azure_ad_b2b.csv which needs to be comma delimited with just “InvitedUserEmailAddress,Name”

It will also prompt for the group name which you want to add invitees to, and bomb out if you get more or less than 1 result (because display names aren’t unique fields in Office 365)

Another prompt is for the project URL, which is where you want invitees to be sent to (which for me, is usually a SharePoint Online site). It’s also set to send the invites out from a generic service account, so change “” in the send-mailmessage line to whatever you’re sending as. Feel free to ask any questions!
