SQL backups fail with error: Database Validation failed


Describes how to fix a SQL backup that fails with the error: Database Validation failed


If a SQL backup fails with the error Database validation failed, it is usually caused by more than one backup solution backing up the database. If more than one backup solution – including SQL maintenance plans – is being used to back up SQL databases, transactional log chains will be broken resulting in failed backups.





To fix the error:

  • Disable backups with all other backup solutions
  • Disable backups with SQL maintenance plans
  • Run a new master backup of your SQL database.


For more detailed information on backup failures and performance issues see Unitrends KB 5062 - Backup Failures and Performance Issues.
