Cant create database (.bak) file..

  • we have a system for banking with sql 2014 database.. i really dont know what really happened,, but suddenly we cant generate a backup .bak file of our banking transactions..

    i found out that while the process of generating the backup file.. the .bak file appears.. but when the process is finished.. the .bak file disappears.. help me 🙁

  • We'll need a bit more information than that. Error messages, for example. What SQL are you running to create the backup?

  • What do you see in the SQL Server Error Log?

    😎

    EXEC sp_readerrorlog;

  • failed : 23 data error (cyclic redundancy check)

    failed : 23 data error (cyclic redundancy check)

    Can you please check your IO subsystems log files, Windows Event Logs and any other applicable log files for error entries!

    Further, run this command and post the full and unedited output:

    DBCC CheckDB ('DATABASE_NAME') WITH NO_INFOMSGS, ALL_ERRORMSGS;

  • Do you have a DBA there?

  • Cyclic Redundancy Check (CRC) error is connected to file corruption.

    To fix this

    Take database offline

    Copy .mdf and .ldf files to alternate location

    Than try to repair database using SQL database recovery[/url]

    If there is some data lost, you can restore copied files
