How to Reduce the Risk of SQL Database Corruption


Today we are going to learn how to prevent SQL database corruption. Let’s start with some facts about how database corruption can occur actually. The SQL database corruption could be completely unsystematic. There are ways from which you find the reason for corruption, but sometimes you are on the wrong track and can’t find the primary reason behind the corruption of the database. And that’s why you have CHKDSK command to figure out the reason for complications. It is much better to reduce the risk of corruption so that you don’t have to face these issues. As a user of SQL Server, you should know that your Server is sharp-witted to predict the problem and already have the solution to that issue. While there are a unit ton of articles floating around the net on the way to fix corruption in SQL database, in this article, we are going to discuss the ways to stop SQL database corruption.

In data-driven businesses, the littlest of bug among the structure information will bring entire operations down. Whereas fixing issues is Associate in nursing after-thought, preventing issues is wiser. Here is a unit the highest six ways that you'll be able to implement to stop SQL server information corruption. There are a lot of ways to detect the corruption in SQL database and remove it from the SQL server. But today I am going to explain 5 ways to reduce the risk of SQL database corruption.

  1. You should Backup your database regularly
  2.  Split your database into more than one part.
  3. You should customize Cron jobs for your database
  4. You should optimize your database regularly
  5. You should check your database file size and hard disk size sometimes all database is lost due to this issue.
  6. You should do hardware and software maintenance regularly.
  7. Alternative Solution.

  • Backup your database regularly:

You’ll have detected it some of thousand-fold already; however, this is that the best safeguard against losses. Backups are an excellent facilitate once databases develop issues. In such cases, backup files square measure won’t restore the corrupted databases, thereby preventing period. You must build a backup of your information regularly so that the possibility of SQL information corruption is scaled back. If the database corrupted, then I will suggest the SQL database repair software. Here is show you how you can back up using MS SQL Server.

After pressing the button you will see the following window:

Press the “OK” button. In this way we backup our files.

  • Split your database:

Split your information. Instead of projecting each object in one MDF file and sharing the complete factor over the network, split the data into 2 pieces: the front-end forms, reports, queries, and knowledge access pages, and also the back-end tables containing your knowledge. Place a duplicate of your front-end information on the native disc of every machine and link back to the tables that are present on a fileserver. It implies that way, less knowledge has got to be dragged around the network and exposed to corruption. Your information will run additional quickly and can enable you to create style changes to the face, whereas still, victimization lives knowledge.

  • Customization of Cron Jobs for your database:

Start Cron jobs to run at regular intervals to confirm no lag in the period.To do that, select a database and press tasks and Back Up:

On the Backup window select Script and Script Action to Job:

Go to Schedules page and press the New button:

Add the schedule of your preference:

  • Optimize your database:

Create scripts that may monitor and determine slow running queries within the info. Often, slow Associates in nested queries end in information issues and an overall lag by taking on over necessary resources. Produce scripts that may determine and optimize these queries and stabilize the SQL server. At a regular basis, do not forget to sporadically monitor and tune-in the server for making certain high performance. Certify that the connections to the server square measure restricted and optimized. The most effective way to maintain the general health of the database is to stay updated with the most recent updates, thus don’t forget to install the last service packs.

Here I show you how you can optimize your database select the last database option. After pressing the button “Database” you will see a new window look like below.

In available space section you will see an option to optimize the size of the database.

  • Checking database file size and storage

When you start employing a new SQL server database, information file size won't be a problem.  Also, the possibilities of big databases obtaining corrupt area unit are tiny. Therefore, it's a decent plan to separate databases of enormous sizes and maintain multiple smaller versions. It additionally helps in liberating up adequate space on the server. As shortly as you see that free area is slippery below the perfect price, begin engaged in liberating it up.

  • Maintenance of hardware and software

Regularly perform memory checks, network observation, hardware-error checks, etc. to avoid bugs and hardware failures. This sort of preventive measure should be distributed sporadically to track the standing of all hardware proactively, and if the requirement arises, to repair all detected problems. Virus and malware will prove very dangerous to your SQL server info. Don't fall prey to such malicious attacks and perpetually keep an eye fixed out for dead of the info. Also, from time to time, check for any traces of malware infections inside the info and use a decent code resolution to stay them cornered.
