The process of storing and managing unstructured data was poor, prior to SQL Server 2008 release.
Earlier Approaches of Storing Unstructured Data
Before the release of SQL 2008, there were two approaches of storing unstructured data. One approach was of storing data in a VARBINARY or IMAGE column. This had transactional consistency and also reduced data managing complexities, but it was performance wise. The other approach was to store unstructured data as disk files and to store the file location in the table along with some structured data linked to it. This approach was good in terms of performance, but did not ensure transactional consistency.
FILESTREAM Feature – Efficient Storage of Unstructured Data
FILESTREAM feature was introduced with SQL Server 2008 for storing and managing unstructured data efficiently. This feature allows storing of BLOB data (like word documents, music file, image files, videos etc) in the NTFS file system. It ensures transactional consistency between the unstructured data (stored in NTFS) and the structured data (stored in table).
FILESTREAM Corruption – Error 7904
Sometimes, when you try to restore MS SQL 2008 database (MDF files) from transaction log backups, database gets damaged. You fail to perform restoration and thus MDF files become inaccessible resulting in data loss. Under such problem, you might encounter the error: “FILESTREAM corruption – missing files, error 7904.” At that time, if you want to regain access of your mission critical MDF files, you must perform SQL database recovery process using an appropriate MDF File Recovery solution.
Original Database Might Not Be Corrupted
The database corrupted when you tried to restore the database from transaction log backups but the original database, from which the backup of transaction was taken, do not damages in most of the cases. In most of these cases, corruption happens on the database that was restored from a sequence of backup logs. The original database might not corrupt. “7904 16 2 Table error: The FILESTRWEAM file for “FileID” was not found.” You can get back your valuable data using a fine SQL Database Recovery Solution to recover corrupt SQL database contents from corrupt MDF files.
A Phenomenal SQL Database Recovery Solution
SysTools SQL Recovery tool is perhaps the easiest and most efficient SQL database recovery tools available around. This MDF file recovery software performs an extensive scan of damaged databases to recover all database items like tables, reports, forms, triggers, stored procedures, etc. If you choose to repair SQL DB and recover corrupt SQL database using SysTools SQL Recovery tool then you will be gifted with a very simple interface which won’t require you to have any prior technical skills to execute the SQL recovery process. The software also has a read-only nature which helps to regain original contents of SQL database. In short, SysTools SQL Recovery software is a phenomenal SQL Database Recovery Solution.
