A RESTORE VERIFYONLY (as mentioned by Dinesh) on the backup file should tell you whether the backup is in a consistent state. If not, then I would strongly suggest to run a checkdb on the source database on which the backup was done. If the CHECKDB output comes back clean, then I would suggest that you take a backup again and try restoring it. Additionally, perform a quick health check on the disk on which the backup files are stored. In case CHECKDB doesn't come back clean, then you need to check the level of corruption and take decisions based on that. If the errors cannot be repaired, then I would suggest a point-in-time recov

18, 2013 SQL Database Recovery SQL Database Recovery Software: A Perfect Solution to Fix SQL Errors SQL Server, one of the powerful Relational Database Management System help users to brilliantly organize, manipulates and retrieves data. However, built up with foolproof algorithms, inconsistencies and troubles are faced by administrators that are indicated via error messages. Below given are some of the warning messages that are encountered by SQL Server users and how database corruption leads to SQL Recovery software need. Import & Export Fail Due to SQL Corruption Cause: In Microsoft SQL Server table, primary key defines the identity of a specific record that helps users to create a relation between databases. In a table, there can only be one primary key. If the row in table defining the primary key is orphan, that is it does not exist anymore for the table, two databases cannot be related and thus relational database management cannot be made possible. The reason behind the above error message is the same, i.e. orphan row having primary key. Error 8931 While Trying To Export Results What is the B-Tree Structure of Database? In SQL Server application, B-tree system helps to define database in a systematic order. When the database is stored in a sorted manner, users can easily perform some general activities like records deletion, new records addition, extracting specific data etc. with minimum effort. There is a set of rules that should be utilized for executing all operations. Sometimes compilation of these B-tree nodes fail as a consequence of which the database gets corrupted. Under such situations, MDF file gets inaccessible and need of SQL recovery software to restore database arises. A Practical Scenario: MS SQL 2000 users come across error code 8931 that states: "Table error: Object ID O_ID, index ID I_ID B-tree level mismatch, page P_ID1. Level LEVEL1 does not match level LEVEL2 from parent P_ID2." Cause: This error message is encountered due to b-tree corruption. The child page P_ID1 is not compatible with the rules of b-tree. Unknown Database Corruption: Data Error In Cyclic Redundancy Check SQL Server database holds importance for its administrator. What if while taking backup of your crucial database, you encounter the following mentioned error message: 10 percent processed. 20 percent processed. Msg 3271, Level 16, State 1, Line 1 A nonrecoverable I/O error occurred on file "R:\data\MyDB.mdf:" 23(Data error (cyclic redundancy check).).
