Databases come in handy when managing an enormous collection of data. Unfortunately, computer damage and other instances can cause the loss of this important data. This article examines the best practices for ensuring fast and efficient recovery of corrupt SQL server MSDB databases.
Recovering corrupted SQL Server MSDB databases can be a daunting task, especially if there is no backup. In such a scenario, the chances of data loss are very high. While there may be remedies for salvaging MSDB files, they do not guarantee full recovery of your information. So, what are your options?
1. Align Your Database Model with Your Business Requirements
The best way to protect your business against data loss caused by corrupt databases is by keeping up-to-date backups of your information. In SQ Server, there are three ways in which you can back up your MSDB database. They include the Simple, Full, and Bulk-logged backup options.
When you use the simple option to back up your MSDB database, only transaction logs that are necessary to restart an SQL Server instantly are maintained. This approach stores less information and cannot implement MSDB database backup logs. This makes it difficult to execute point-in-time database recovery operations.
If the nature of your business requires you to back up all transactions, as with financial institutions, then this option would not be appropriate. This is because it may lead to partial data loss. Moreover, it doesn’t meet the threshold to support high availability databases that may require functions such as Always On or mirroring. These functions are best supported by the Full database backup and recovery model. Here, all transaction logs are saved, thus making it possible to perform near real-time point-in-time database recovery operations.
On the other hand, the Bulk-logged model combines both Simple and Full SQL Server MSDB database recovery options. It is most suitable when performing Bulk Import functions. On the downside, this model doesn’t support point-in-time database recovery.
2. Use Database Backup Logs to Restore Your Corrupted Files
When your MSDB file is corrupted, it will be marked as “suspect” and you will not be able to open it. At the point, your database backup will come in handy. When performing a database restoration operation from a backup, make sure that both the source and destination servers are of the same version. You will also require exclusive access to the database for you to execute this operation successfully. Therefore, make sure that the SQL Agent service is not running before attempting the MSDB database recovery procedure.
3. Use Proven SQL Recovery Software
If you cannot restore your MSDB database from backup files, consider using recovery tools such as DataNumen SQL Recovery. Besides increasing efficiency, automated database recovery tools act as a fallback plan when other methods fail. They also simplify the data recovery process so that less experienced experts can perform complicated operations just as seasoned pros would do.
As you shop for an SQL recovery tool, make sure you pick for an application that is affordable and meets your business needs. It should also be compatible with your operating systems and SQL Server version. Similarly, make sure that the application has a proven track record of a high database recovery rate. If you are performing a bulk database recovery operation, go for a tool that can support the restoration of extensive databases.
