Error Messages while restoring the MS SQL Server database

Restoration of data from an updated database backup allows you to overcome almost all SQL Server database corruption scenarios. It is therefore, always recommended to maintain a systematic database backup on some other storage media as well. While restoration of data is an easy process, it might result into an error message, which prevents you from restoration of the database. In such situations, an easy way is to restore the data from any other updated database backup. However if in case, no other backup is available or backup falls short to restore the data, then you will need to opt for advanced third-party SQL Recovery application.

Consider a practical scenario, where you encounter the underneath error message while restoration of data:

“Msg 8967, Level 16, State 216, Server , Line 2
An internal error occurred in DBCC which prevented further processing. Please contact Customer Support.
DBCC results for ''.
Msg 8921, Level 16, State 1, Server , Line 1
Check terminated. A failure was detected while collecting facts. Possibly tempdb out of space or a system table is inconsistent. Check previous errors.”

On viewing the your SQL Server log, you view another error message:

“2007-05-26 07:13:49.21 spid58 DBCC encountered a page with an LSN greater than the current end of log LSN () for its internal database snapshot. Could not read page (file id:page id), database '), LSN = (), type = 32, isInSparseFile = 1. Please re-run this DBCC command.”

While the restoration process halts, the data stored in the database becomes inaccessible.


The above error message primarily occurs when the DBCC CHECKDB command is unable to serve the required checks that confirm the consistency of your database. These checks could not be performed due to numerous reasons, such as SQL Server database corruption, metadata structure damage, and more.


To resolve the above error message and to access the database records, you will need to use advanced SQL Database Recovery tool that provides comprehensive repair of corrupt database. Such SQL Repair tools are non-destructive in nature as they do overwrite or modify the original records of the database.
