Sql Server Deduplication: Importance of Server Deduplication

Overview: Microsoft sql server deduplication

You may have heard the term ‘Sql Server Deduplication‘ or ‘Microsoft sql server deduplication’ many times before in the context of SQL database and data loss prevention, but what is it? The simplest way to define it is that it is a way for a physical or logical server (or both) to store more data than what can be accessed by any individual or group of users. This data loss prevention (DLP) technique is also known as copy-on-read scan or copy-on-write scan. One of the reasons that companies resort to this is because they have dedicated server resources for each user which in turn requires them to save transaction logs to a different location so that the transactions for each user are not mixed up.

What happens when an SQL transaction log is saved to a different location?

It becomes doubly protected since then every time a transaction is saved it is logged separately in the transaction log. If one user tries to access the same data saved in two different locations, the data from both logs will be lost. This is why it is very important for SQL servers to have Deduplication features. When these are available, the data loss that can be expected is considerably minimized.

How Sql Server Deduplication can help?

In order to understand how Sql Server Deduplication can help your company, it is important to know a bit more about the process itself. Basically, when a user tries to make a request or a modification to a table, he will be requiring the amount of space needed to save his data. Since the transaction log copies all of the information into a temporary file on the server before it is committed to the server, there is a possibility that if the client’s session is cut short, the data will be lost along with his entire session.

Now, you may be wondering ‘why would an SQL server need to be used in the first place?’ This is because the data that is stored in such a server is already encrypted. Therefore, even if a hacker manages to somehow get access to the server and gain access to the data that is being stored within, he would be unable to read it due to the encryption that is present. This is one of the most secure ways in which data is kept safe and secure.

Aside from this, there are many other benefits that can come from using a server like this. One of them is the ability to control over the amount of data that is stored within one server. This is because of the built in limitation feature. The amount of data that can be stored in one database is determined by the amount of memory that the system has. If you are looking for a way to improve the performance of your company’s data management system, then using a Dedicated SQL Server is certainly one of the best options to take.

Prevent data loss

While Sql Server Deduplication can definitely prevent data loss from happening, it does not completely eliminate it. There are certain programs or software that can take care of the problem of loss of information from such accidents. However, these programs are not very user friendly and often times they require technical knowledge to properly implement them. Hence, it is always best that users use these tools as the last resort.

Deduping SQL Server table

As mentioned earlier, Microsoft sql server deduplication is just a tool that can reduce the amount of data loss from such accidents. It can not totally solve the problem. Data duplication is only one of the ways by which you can minimize the chances of your company losing important data. You should always make sure that you are constantly monitoring the performance of your entire server and check what could be causing such data loss.

Closing Notes: Microsoft sql server deduplication

In addition to this, it is also very important that you constantly change the application that is running on your SQL server in order to avoid data loss. This is one of the best preventive measures that you can take against data loss. You have to ensure that the application that you are running is not responsible for causing such data loss in case any such event occurs. If you fail to do this, you will be very likely to suffer a huge loss. Hence, always try and find out and eliminate such threats before they cause you a lot of trouble.
