Veeam Explorer for AD – the search filter is invalid

These blog posts serve more as a reminder to myself than anything else, especially if I can’t find any other information regarding the problem encountered. So as is tradition, my next post is again about documenting an error I’ve witnessed that was simple and easy to resolve but easily forgotten (at least for me it is).

So my job involves a fair bit of demonstrating what features and capabilities Veeam has along with knowledge transfers. I especially love showing off the Veeam Explorer’s, they certainly making restoring application items a breeze for the most part. I find one of the easiest and quickest ways to demonstrate what the Veeam Explorer’s are all about is to demonstrate a quick restore using Veeam Explorer for Microsoft Active Directory.

With full permission granted, I like to make a small adjustment to the ‘description’ field for an inactive user that lives on the domain, making a small typo for example. After making the change, loading up Veeam Explorer for AD, letting Veeam filter out the unchanged data between production and the restore point, finding the change I introduce and attempting to restore the original ‘description’ value back. Usually, this goes without a hitch but this time Veeam came up with the below error.

Collected SQL Server transaction logs do not match any existing database backup: [DB Name]

Experienced this error ‘Collected SQL Server transaction logs do not match any existing database backup: [DB Name]’ recently for a customer, 

Luckily there is a Veeam KB article on for this error which can be found here.
Unfortunately, the solution provided ‘ Start the Backup Job (right click the job > Start).’ didn’t fix the problem. Well to be precise, it worked for about 24 hours and then the error returned.

Implementing the 3-2-1 backup rule with Veeam & Azure

One of the tried and tested rules that can effectively address any failure scenario is called the 3-2-1 backup rule. This backup rule is becoming more and more important as organisations continue to virtualise their mission critical data, making the protection of that data becomes more vital than ever.

The 3-2-1 rule became a popular concept thanks to Peter Krogh, a well-known photographer who wrote that there are two groups of people: those who have already had a storage failure and those who will have one in the future.

In other words, the 3-2-1 backup rule means you should have 3 copies of your production data, on 2 different types of media and 1 offsite.

The purpose of this post is focused on getting your backup data offsite, and how we can leverage Microsoft Azure and Veeam together to help meet the 3-2-1 backup rule.

 

How can I get my data offsite to Azure?

Well, there are currently three main ways to get your data offsite and into Azure Cloud.

Figure 1: Veeam to Azure

Option 1

The first method is to utilise an on-premises storage appliance called a StorSimple. The StorSimple can be deployed either as a physical appliance or as a virtual software appliance which caters for the majority of organisations requirements. By utilising the StorSimple capability to automatically archive Veeam backup data out to blob based Azure storage, we can achieve offsite backups. The StorSimple is a great bolt-on solution for existing Veeam deployments with relatively quick deployments and easier to use interfaces.

The flexible architecture of StorSimple is ideal for customers who want to externalise more than just their backups and is ideal for large volumes with usage of Azure native storage.

Limitations that should be considered are the extra appliance that needs to be deployed and maintained. Also, consider that while there is a virtual software appliance available there is a cost for any physical appliances that are acquired. A faster internet connection is recommended to meet any established recovery point objectives (RPO).

Figure 2: Veeam to StorSimple to Azure

If Veeam requires access to the archived data within Azure, the StorSimple will automatically pull the data back. A fast internet connection is recommended to ensure your offsite backup requirements can be met. No additional Veeam licenses are required for this option.

Option 2

Option two is to externalise with a dedicated link to an Azure site as Site to Site Link (Azure ExpressRoute), SSL Direct Link to Azure or using a private network (vNet) in Azure.

Offsite storage is made available by configuring a link between the on-premises Veeam server and the Azure storage which is used to store the offsite Veeam backup data. Optionally a virtual machine can be created in Azure to provide WAN Acceleration to improve performance.

The benefits of this method is available to all organisations, no appliance needs to be deployed taking up valuable rack space or consuming resources living on your hyper-visor hosts as a virtual appliance. This option also does not require any additional Veeam licenses.

Things to consider are the link that is necessary which may impact on performance and possibly workload that may share the link. Costs associated with the Azure ExpressRoute need to be considered as well. This option is not recommended for multi-location infrastructures as it can be complex.

Option 3

The third option is to send backups offsite to Azure using Veeam Cloud Connect.

Veeam Cloud Connect is a technology that enables sending backup data to an offsite location managed by a Service Provider or the organisation themselves.

Figure 4: Veeam Cloud Connect for the Enterprise

There are two flavours of Veeam Cloud Connect:

a. Veeam Cloud Connect for the Enterprise

Veeam Cloud Connect for Enterprise allows enterprise organisations to operate their own Hybrid Cloud by acting as their own service provider, they configure the necessary infrastructure in Azure to receive and manage the off-site backup data.

There are several considerations for this option as it is geared towards enterprise customers. Veeam Cloud Connect for the Enterprise requires the organisation to own the Enterprise Plus edition of Veeam – also if the customer is not in an Enterprise Agreement (EA) with Microsoft, then there is a 100 socket minimum of Veeam Enterprise licenses. If the organisation owns an EA with Microsoft, then there is no socket minimum. In either case the customer must match licenses 1 to 1.

For example, if ACME company has an EA with Microsoft and owns 86 sockets of Veeam Enterprise Plus, they would purchase 86 sockets of Veeam Cloud Connect Enterprise. Without the EA they would be required to purchase 100 sockets.

b. Veeam Cloud Connect

A service provider will host the offsite backup storage in Azure which is presented to organisations with on-premises Veeam. The service provider’s backup data can be encrypted at the source (before it leaves your network perimeter), in flight and at rest. This method is the easiest way to externalise to Azure, its ideal for multi-site configurations and you keep the same interface and console.

Figure 5: Veeam Cloud Connect

Veeam Cloud Connect is included within the Veeam Availability Suite, Veeam Backup & Replication and Veeam Backup Essentials for all organisations at no additional charge and with no additional licensing required. However, organisations will need to acquire a subscription to the appropriate storage resources from a service provider of your choice in order to use it.

 

Understanding Cloud Computing

Great analogy for cloud computing.

Imagine if tap water didn’t exist. Every household would need to dig a well. Doing so would be a pain. Wells are expensive to build and expensive to maintain. You wouldn’t be able to get a large quantity of water quickly if you needed it—at least not without upgrading your pump. And if you no longer needed the well, there would be no store to return it to, and no way to recoup your capital investment. If you vacated the house, or the proper plumbing was installed in your house, you would have invested in a well you don’t need.

Tap water fixes all of that. Someone else spends the money and builds the right plumbing and infrastructure. They manage it and ensure that the water is clean and always available. You pay only for what you use. You can always get more if you want it.

That, in a nutshell, is what cloud computing is all about. It is data center resources delivered like tap water. It is always on, and you pay only for what you use.

Wait on the Database Engine recovery handle failed. Check the SQL server error log for potential causes

When installing Microsoft SQL Server 2014, you might come across a situation where the setup fails towards the end of the installation with the following error,

“Wait on the Database Engine recovery handle failed. Check the SQL server error log for potential causes.”

Error when installing SQL

If you ignore the error and continue with the installation the following will be displayed.complete with failures

After scouring the web for a fix I was able to resolve the problem with the below steps. Some answers asked me to both uninstall SQL Server and delete a specific set of SQL registry entries, I did not delete any registry entries. I fixed the error by only uninstalling SQL 2014 using add/remove programs.

After SQL 2014 was uninstalled, I restarted the server then started the installation by right clicking on “setup.exe” and selecting “start as administrator”. Proceed with the installation normally until you get to the Server Configuration section,

Before change

On the SQL Server Database Engine service, click the drop down option to select a new user.

click advance

Click “Advanced”

click find now and select network service

Click “Find Now” then browse to “Network Service”, select this user and click OK.

After change

It should now look like the above, now continue with the installation.
You should no longer have the issue.
