Things to Practice to Effectively Prevent SQL Database Corruption

We seem to be living in a highly digitalized world that depends predominantly on data and analytics. Today, organizations across the world, consume, generate, modify, and even exchange an incredible amount of data. Your business decisions will be adversely impacted if you fail to monitor and keep track of critical data your business has been consuming, generating, exchanging, deleting, or modifying. 

As such, it is of pivotal importance to focus on preserving data integrity, particularly, if you are running a data-driven business. Preventing SQL database corruption will be a critical asset to safeguard you from placing your organization at risk by making irresponsible and risky business decisions.

In this context, you should know that most of the organized data in the world are stored and maintained on databases, right from gigantic scientific data sets to airline reservations. According to experts at Forbes, the metadata not only helps describe data, but also, is indexed often for rapid searches. We know that this metadata Databases help collect, organize, find, and even analyze data. 

SQL database corruption may not occur frequently; however, when it takes place, it may culminate in data loss and downtime. On some occasions, the issues may be detected. However, at times, the problem may go unnoticed until you land up in a major mess. That is why you may opt for CHKDSK for figuring out the precise issue and fixing it. However, you may successfully prevent database issues from taking place. 

Remember that SQL Server is super-intelligent and can anticipate issues and present solutions for fixing them. Moreover, you have easy access to an array of software, tools, and utilities that may come in handy in detecting corruption and eliminating it from the server without compromising anything at all.

Preventing SQL Database Corruption

Database problems and errors may occur all of a sudden, and may give you a panic attack. For allowing things to go on seamlessly and uninterrupted, experts recommend practicing a few things discussed below. It could be quite challenging to detect the precise cause of the error once the database gets corrupted. Even a petty blunder may adversely impact the database and abruptly stop the workflow. It is, therefore, a wise move to proactively prevent errors and server

Create Custom Cron Jobs

You can go on monitoring your database while sleeping simply by utilizing Cron, the super-effective time-based scheduler utility. It is helpful in creating jobs that could be performed at odd hours. You may use Custom Cron jobs for, first of all, detecting anomalies and errors in the database. The Database Administrator may then go about repairing these irregularities one by one. You may focus on setting up Cron customized jobs to proceed at consistent or regular intervals for ensuring no delays or holdups in uptime. Follow these steps.

  • Start SQL Server Agent and SQL Server Management Studio
  • Right-click specifically on Jobs for selecting the New Job option
  • Go to the General tab and enter the job name. Next, write the command for scheduling the task. 
  • Enter the precise schedule for the job. Your next step will be setting up an alert notification.
  • Finally, choose the target server for a specific job.

Consider Using the Repair Option with Caution and Care

You may use DBCC CHECKDB T-SQL for running an effective database error check. It should help repair the database. However, it is mandatory to understand that the DBCC CHECKDB should not be the first parameter to consider for problems associated with the database since it may lead to data loss.

Avoid Upgrading SQL Server

It is pretty common on the part of users to upgrade their SQL Server whenever they come to know that a new version is available. Everybody is over-enthusiastic about the new version as it is supposed to be an excellent combination of new features, speed, bug fixes, etc. However, sometimes upgrading SQL Server may trigger issues while fixing the problems relating to the corrupt database.

Do Not Opt for Server Restarts Frequently

Restarting the server frequently is not the right way to deal with the situation when an issue or error occurs. When objects are corrupt, we find that the database may be inaccessible, it may stop working, and it may crash. If the user does not have the requisite knowledge or relevant information, it is best to do ample research before trying any tricks.

Consider Preventing Dirty Shutdown

Dirty Shutdown seems to be the chief reason leading to database corruption. Hence, it is recommended by experts to shut down the SQL Server carefully. It is the responsibility of the DBA to examine the number of users connected to the server and then go about monitoring it as per the conditions. In this context, you should realize that system maintenance could help detect issues in the database and enhance the overall SQL server performance.

Maintain Backup for SQL Server Database

It is the most critical thing to practice if you are handling the SQL server database. Backups are regarded as insurance for worst-case scenarios. However, backups are the only way to facilitate faster data recovery. DBAs should focus their attention on performing differential data backups. This is best for ensuring no loss of data. You may complete your database backup and choose a suitable recovery model to cater to your unique requirements.


It is a good idea to create and follow some good practices, particularly if you are new and not that adept at database administration. If you are an experienced database operator, you may tally to identify things you are not practicing to prevent SQL database corruption.
