Microsoft usually recommends you to use a SAN (Storage Area Network) or locally attached hard drives to store your MS SQL Server database (MDF or Master Database File) because it optimizes the reliability and performance of Microsoft SQL Server. Use of the network database files (the files stored on NAS [Network Attached Storage] or networked server) isn't enabled for MS SQL Server. However, this configuration may damage your SQL Server database in some cases of system failure. In such situations, you must have an absolute backup of your significant database to extract inaccessible data from it. In the other case, you need to go for master database file recovery solutions to get your valuable data back.
Although, network file support is not enabled by default in Microsoft SQL Server, you can manually configure MS SQL Server to store all your database files on NAS storage server or networked server. The servers, which you employ for this configuration, must fulfill MS SQL Server requirements for write-through guarantees and data write ordering.
When you try to store SQL Server database on UNC or mapped network location can result into any of the below mentioned error messages:
5105 “
Device Activation Error.”
5110 “
File 'file_name' is on a network device not supported for database files.”
This behavior of Microsoft SQL Server is expected. The Trace file 1807 go around the check and enables you to configure MS SQL Server to store databases on network-based storage devices. Microsoft SQL Server uses the transaction location and related recovery logic to insure transaction database consistency in case of an improper system shutdown or system failure.
SQL Server recovery protocols are based on the capability to write data directly to hard drive so that when database manager receives operating system I/O (Input/Output) write request, recovery system can guarantee that write operation is successful. But, any failure due to hardware or software reasons can cause in total or partial data loss and severe database corruption in case of system failure.
In the event of database corruption, you must employ
MDF recovery solutions to repair and restore the corrupt Microsoft SQL Server database.
You can easily, quickly, and successfully recover MDF file using commercial recovery tools, known as
SQL recovery software. They offer absolute recovery in all database corruption scenarios, using high-end scanning techniques.
Stellar Phoenix SQL Recovery is the most advanced and efficient utility to repair and restore corrupt MDF and NDF files of MS SQL Server database. The software works well with Microsoft SQL Server 2008, 2005, 2000, and 7.0. It restores all database objects like tables, reports, macros, triggers, stored procedures, and constraints.
