Microsoft SQL Server stores all your valuable data in MDF (Master Database File) in the form of tables. The data is organized using database index, which makes it easy to locate and access stored data. Sometimes, the database grows unexpectedly and performance of the database gets decreased dramatically. To control the database growth, you can use native options of Microsoft SQL Server, such as 'Filegroup'. If you do not take any such actions, the database may crash and get damaged. This behavior causes serious data loss and requires
SQL recovery to be sorted out, if there is no backup in place.
Microsoft SQL Server offers various methods to help supporting the database growth. From the database planning point of view, one of the most important topic that must be covered is the 'Filegroup'. It can be considered as a logical data storage unit to hold the SQL Server database objects, which maps to multiple files or file system file.
Every Microsoft SQL Server database contains a filegroup by default, which is known as primary filegroup. It is used to support the user and system objects of the MDF database. You can allocate additional mass storage devices to Microsoft SQL Server to support the assumed performance and needed growth. You can create new files and filegroups on new hard drive. The database objects can be transferred to newly created filegroups for spreading I/O (Input/Output) over the additional hard drives.
Under some circumstances, the filegroups may get damaged and stored database files become inaccessible. In a practical scenario of this problem, you may come across the below error message when you try to access a Microsoft SQL Server database:
Unable to process index I_NAME of table O_NAME because filegroup F_NAME is invalid.
After the above problem, you can not gain access of MS SQL Server database and stored data. It leads to critical data loss situations and you need to recover SQL database to get your mission-critical data back.
A complete backup is the greatest help in such cases. However, if backup is not valid or available, SQL Server recovery software can help you to extract data from the database. The applications are particularly designed to scan whole database effectively and restore it in all corruption scenarios. They offer safe
MDF repair with read-only and non-destructive conduct.
Stellar Phoenix SQL Recovery is the most efficient and powerful utility to ensure easy and absolute recovery of inaccessible database. It restores all MDF file objects, such as tables, reports, forms, macros, triggers, stored procedures, and constraints. The software works well with Microsoft SQL Server 2008, 2005, and 2000.
