How Do SQL Server Backups Work?



The essence of data backup cannot be overemphasized. One of the biggest advantages of adopting Microsoft technology is that your business processes will enjoy fast tasks completion. In essence, if you have a business with a team of employees, adopting Microsoft technology will enable your team to achieve increased output with little effort. For example, if you own a marketing company, you can use Microsoft technology to reach out to different clients regardless of their jurisdictions.

So, in this blog post, we will take a look at how SQL server backups work. But before we dive deeper, let's quickly define what SQL server backups are and also explain the different types of data backups.

What is a SQL Server Backup?

A SQL Server backup can be defined or described as a process of putting your business data into different backup devices to create robust protection for your data. In the context of this blog post, a backup device can be anything from a tape, file, disk, or even the cloud.

Backing up your server has so many advantages not only for your business but also to protect your stakeholders, clients, and employees. Storing an important database of your business in a safe and secure location can potentially protect your business from catastrophic data loss. During a natural crisis, one of the ways to protect your business data is to back it up using the SQL Server database by Everconnect Data Systems. When you are backing your database you can also recover your data in the event of a crisis. Reasons why you need to backup your database are:
  • Media failure.
  • User errors 
  • Hardware failures. This can happen to any computer user. There are times that you would power up your system and you discover that some parts or components of your system have gone bad.
  • Natural disasters. You can create a backup system in different locations within your office using SQL Server backup. In the event of a natural disaster, you are sure that your daughter will be protected.

Types Of Backup In SQL Server

The SQL server has four different types of data backup. In this section, We will take a look at the four different types of data backup that the SQL Server supports.

Full Backup

The first and most popular type of backup in the SQL server methodology is the full backup method. This method has all the entire database backup at the time the machinery was set in motion. It encompasses all the details of your database by its data tables, indexes, views functions, stored procedures, and much more. All the databases will back up at a specific time that you have allocated for the backup process. The full backup method is touted to be the foundation of every restore sequence in the SQL server concepts.

The only exception in this method is that the transaction log will usually be back or separately this is to ensure that you recover your database in the event of any natural disaster or crisis. Without a full backup mechanism in the event of a crisis, the chances of recovering your database would be very slim.

Differential Backup

The next SQL backup method is what is known as the differential backup method. This method is only responsible for the capturing of small changes in your data that were left behind by the full backup method. In simple terms, the differential backup method is usually called upon when there is a need to back up the simple or small changes that were left behind during the full backup process. In the event of a crisis or an outage, businesses can leverage both the full or differential backup processes to recover their databases.

Transaction Log Backup

Another important SQL Server backup method is known as the transaction log backup. This is a fine that you can use to store or transactions relating to your business on a specific database. This backup helps to maintain a record of all the modifications that you have done to your business data. It also captures important information that was released into space in a long time so that you can always use this information while there is a national disaster or crisis. Businesses that omit this backup method can always fall back to the full backup method or the differential backup method whichever one that you decide to stick with, you are good to go.

Copy Only Backup

A Copy Only Backup is a type of backup that does not generally alter the differential. Businesses that understand the usage of the SQL Server backup method can leverage the copy-only backup method of backup to record or capture their business database so that in the event of a crisis they can easily retrieve all important information about that business. The perfect time to do this type of backup is during the middle of the week so that you will not encounter any disruption from the system.


In the digital business economy, businesses are thriving and scaling due to the advantage of the internet. Before the advent of the internet, brick-and-mortar businesses relied on several strategies to grow their business and also offer value to their customers. But in the digital age, the internet has permitted businesses to leverage technology to solve different problems that small businesses face. As a small business owner, there are so many challenges that your business might face. From payroll challenges, accounting, sales, administration, and advertisement, small-scale businesses in the 21st century face a lot of challenges that technology can help to resolve.

SQL Server can help you better manage your team. You can see the positive effects that technology has in the face of the coronavirus pandemic that ravaged the global economy, companies that rely on technology to promote their goods and services were still thriving even though the government had imposed a global lockdown, which resulted in massive loss of job and shutdown of businesses. Therefore, you must adopt or integrate SQL servers into your business processes.
