Actions to be taken in case of SQL Server corruption for safe data recovery

Microsoft SQL Server is one of the widely used relational database applications of the recent time. Many industries as well as entrepreneurs have been using SQL Server database for its advanced features as well as efficient data storage architecture. Apart from organized storage, SQL Server provides a good response to queries for retrieving the required piece of information. But, there are times, when even this reliable database gets corrupt and you fail to access all your important data. In such critical situations, you need to act very carefully; otherwise you may end up loosing your precious data in the troubled SQL Server database permanently.

No DBA wants his database to go weird and thus implies the best possible data safety measures to guard against any possible instance of corruption. But, there are many unexpected incidents (virus/malware infection, file system corruption, operating system malfunction etc.), which cause corruption to the SQL database and data inaccessibility.

But with SQL recovery software available in the market you can easily recover data from the corrupt SQL Server database. However, before recovering the database or during the process it self, users commit mistakes, which make the database recovery more complex. Hence, prior to the recovery job, it is extremely important to handle the database properly. Below are few points that you must keep in mind, in case of SQL Server corruption:

  • Don't take any weird step of data recovery by being panic
  • Never detach the database
  • Never restart SQL
  • Don't just run repair, without any clue about the corruption
  • Run an database integrity check
  • Perform a thorough root-cause analysis

After encountering SQL corruption, many users severely panic and make silly mistakes that lead to permanent data loss. But, remember that being panic, you are not going to recover your database back. So, stay calm and make a note of the errors as well as the sequence of events, leading to the corruption.

Similarly, in case of corruption, the database floats in a transition state and restarting or detaching the database, you are going to make some unwanted changes to take effect. Hence, it is better advised to perform a through analysis of the error messages, before performing any repairing operation.

Once, you finish analyzing the situation, you can take the help of any reliable SQL recovery software to retrieve the data back. Importantly, these database recovery utilities are completely safe and do not cause any harm to the data in the database.
