SQL database corruption is something that doesn’t take place frequently. But when corruption takes place, it can result in fatal data loss and downtime. If you’re fortunate enough you will be able to detect the problem. But sometimes the issues will remain unnoticed until the situation gets out of your hand. This is the primary reason why you have the CHKDSK option.
If you think that the SQL database is corrupted and has become unresponsive or inaccessible, you need to run the command DBCC CHECKDB so that you can determine the root cause of corruption in the SQL database. In such cases, you need to use a repair tool that will help you fix this problem.
However, one of the best things is that you can prevent SQL database corruption from taking place. The SQL Server runs on an advanced algorithm that will anticipate problems and come up with solutions that will fix them. You can use various useful tools as well as utilities so that you can detect the corruption of the SQL database.
How Can You Prevent the SQL Database from Corruption?
If you happen to run a data-driven business, a small issue within the organizational database will cause various problems such as data loss and shutdown of the entire operation. While you need to pay close attention while fixing the problem, you also need to know how you can prevent the problems from coming back. Here are some great ways you can prevent SQL server database corruption.
This is something you always need to remember if you want to prevent database corruption of the SQL server. You might have heard this point hundreds of times, but some people still forget the importance of backup. When you take a backup of the data, you will be able to create the best way to safeguard your valuable information from potential losses. As per G2, backup is extremely important.
Taking backups regularly will also create proper continuity of business. When the database of the SQL server develops a problem, the backups are something that will prove to be your lifesaver. You can also use the backup files so that you can restore the corrupted database of the SQL server. Not to mention, you can also reduce downtime.
Check the Integrity of the Database Regularly
Even if you create a successful backup of the SQL server database files, if you don’t test them and determine their usability, they might not help you in tough situations.
Just taking a backup of the SQL Server database is not sufficient. Instead, you need to have a robust backup that will help you enhance protection against database corruption. This is why you always need to test the backup after you create it.
The best way to test the effectiveness of the backups is by storing the SQL database daily from the recent backup copy. This way you will be able to perform DBCC CHECKDB which will help you validate whether the backups are good or not. Additionally, you can also run an integrity check on the new database of the SQL server to make sure there are no issues present. After you perform the database restore, you can automate the DBCC CHECKDB.
Personalized Cron Jobs
Even if you’re sleeping, you will be able to monitor the database of the SQL server. However, you will have to use Cron which is one of the most famous time-based schedulers. This is an effective utility that will help you create jobs that can be implemented at either odd or even hours.
Personalized Cron jobs can be implemented to detect the problems that are associated with the SQL server database. After implementing, you can start fixing the issues one by one. Consider setting up the Cron jobs at regular intervals so that you can ensure no lag in the uptime.
Regular Updates and Optimization
Consider creating scripts that will identify and monitor all the slow queries in the SQL server database. Most of the time, the slow queries will cause various problems. Not to mention, the overall lag will also consume more than necessary resources. When you develop scripts that will optimize and identify these queries, you will be able to stabilize the SQL server. Make sure you always monitor the server periodically so that you ensure the best performance.
On the other hand, ensure that the connections to the SQL server are not only optimized but also limited. One of the most effective ways to maintain the overall health and longevity of the SQL server is by keeping the server patched and updated. This will help you boost the protection of the against different types of threats such as SQL computer worms, that can affect more than 80,000 SQL servers within a couple of minutes of deployment.
These are the methods you need to follow so that you can prevent corruption of the SQL server database. Make sure you visit our website if you have any more queries.
