Thousands of users save their important data in SQL Server Database. But there is always a anxiety with such question which maximum users asked “Is it safe to save data in SQL Server Database?” If you've read any of the SQL Database Corruption case studies over the last year, you’ve seen NOONE can surely suggest “YES”!!
It is all depends on you to be aware about how they can safe their data from data loss because it is a database & all database suffer with data corruption issues, I am sharing some steps to handle these corruption issues.
First, analyze your full database, what steps need to take if your database gets corrupt? How do you handle database corruption errors? And how do these steps fit in all corruption scenarios?
I read in many forums & articles, everyone suggesting to restore the database from updated backup that fixes the data corruption problem. But in reality this process only fixes the symptom of the issue. So I want to share some useful steps that will help you to safe your database from data loss:
1) First Analysis the Root Cause of the issue: First find out the cause of the corruption and take steps to make sure it won't happen again. It can be done by DBCC CHECKDB command. After running DBCC CHECKDB command on your database, it shows error message through this you can take better steps to correct the problem.
2) Restore From updated backup: This strategy depends on when you take your database backup. If corruption occurs before taking database backup then the backup copy also contains corrupt version of the database and in this case recovery process will become more complicated. In this case restore database from the most recent database backup to a different location and then run DBCC CHECKDB . If no corruption found then you should be able to restore without losing any data. If corruption exists then go for next step.
3) If you don't have backup: If you don't any valid backups or your backup copy also get corrupted the Running repair command should only really be done it should always be your last step as you'll most likely lose data. In this case first you should make a backup of your database - just in case something goes wrong. There is one more strategy which can help you to recover data in case of no backup copy & without data loss that is third party SQL database recovery software. The software helps user to recover corrupt database with fast scanning process. The software almost works in all corruption scenarios & also recovers primary & secondary files of the SQL Server database.
These 3 points surely help you to handle database corruption errors, no matter what may be the cause of database corruption. These points will also guide you to safely recover your corrupt SQL Server database.
